Detailed Description
The embodiment of the application provides a method and a device for merging seismic data.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method for merging seismic data. The method of seismic data consolidation may provide seismic exploration auxiliary data for a destination work area and at least two seismic data acquired by different types of acquisition systems; the seismic data correspond to the types of the acquisition systems one by one; the seismic exploration auxiliary data is used for representing target shot points and attribute information of a plurality of target detection points related to the target shot points; and the appointed seismic channel data in the seismic data correspond to the appointed shot point and the appointed wave detection point.
In this embodiment, the target work area may be a complex transition zone area. In the complex transition zone area, two different types of acquisition systems respectively including wireless instruments and wired instruments can be adopted to carry out joint acquisition on the seismic data. For example, the acquisition is performed by using an acquisition system including a wireless device for a land area in the complex transition zone area, and the acquisition is performed by using a wired device for a transition zone such as a sea area, a low-lying water area, or a swamp zone in the complex transition zone area. Wherein, in the process of joint acquisition, a plurality of types of detectors are required to be used for different areas. For example, on land, a wireless node type detector can be used for collection, in a transition zone, a single-point swamp detector can be used for collection, and in a sea area, submarine cable double-detection collection can be used.
In this embodiment, the format of the seismic exploration assistance data of the target work area may be SPS (seismic survey format for land 3d survey) format. The seismic survey assistance data may be used to characterize a target shot and attribute information for a plurality of target survey points associated with the target shot. The seismic exploration auxiliary data can comprise a pile number and a shot point code of the target shot point, a pile number and a demodulator probe code of the target demodulator probe, and incidence relation information between the target shot point and the target demodulator probe. The target shot point can be any one shot point in the target work area. The target geophone points may be geophone points arranged around or on a survey line set in a seismic survey observation system of the target work area, which geophone points form an associated geophone combination with the target shot. The pile numbers of the target shot point and the target demodulator probe can be used for representing the line number and the point number of the target shot point and the target demodulator probe. The shot codes may be used to characterize the type of seismic source located at the target shot location. The detector point code may be used to characterize the type of detector located at the target detector point location.
In this embodiment, the at least two seismic data may be acquired by different types of acquisition systems, both by way of seismic exploration and by way of data acquisition. And the seismic data correspond to the types of the acquisition systems one by one. For example, two types of seismic data are acquired by an acquisition system including wireless instruments and an acquisition system including wired instruments, respectively. And aiming at the at least two types of seismic data, the specified seismic channel data in the seismic data correspond to the specified shot point and the specified demodulator probe. For example, during seismic exploration, after a seismic wave is fired at the designated shot point, the seismic wave is launched through the formation, received by receivers at the designated pickup point associated with the designated shot point, and the designated seismic trace data is generated.
FIG. 1 is a flow chart of an embodiment of a method for seismic data consolidation according to the present application. As shown in FIG. 1, the method for merging seismic data comprises the following steps.
Step S101: determining target seismic trace data corresponding to the target shot point and the target demodulation point from the at least two seismic data based on the pile number and the shot point code of the target shot point and the pile number of the target demodulation point in the seismic exploration auxiliary data; wherein the shot code is used to characterize a type of seismic source located at the target shot location.
In this embodiment, determining target seismic channel data corresponding to the target shot point and the target geophone point from the at least two seismic data based on the pile number and the shot point code of the target shot point and the pile number of the target geophone point in the seismic exploration auxiliary data may specifically include determining whether the seismic channel data corresponding to the target shot point and the target geophone point can be queried from the at least two seismic data based on the pile number and the shot point code of the target shot point and the pile number of the target geophone point in the seismic exploration auxiliary data. If the target seismic channel data cannot be inquired, the appointed channel data can be used as the target seismic channel data corresponding to the target shot point and the target wave detection point. And the amplitude value of each sampling point in the specified null channel data is zero. Therefore, the situation that follow-up seismic data processing cannot be normally carried out due to the phenomenon of channel loss in the seismic data acquisition process can be avoided. If the target seismic channel data can be inquired, the inquired seismic channel data can be used as the target seismic channel data corresponding to the target shot point and the target wave detection point. Therefore, the seismic trace data corresponding to the same shot point and the wave detection point associated with the shot point can be screened from the at least two kinds of seismic data, and a data basis is provided for the effective combination of the seismic data under the joint acquisition mode of the same shot point and the multi-type wave detectors in the at least two kinds of seismic data.
In one embodiment, in order to facilitate subsequent determination of whether target seismic channel data determined from the at least two seismic data satisfies a specified condition and to process the target seismic channel data according to the determination result, the target seismic channel data determined from the at least two seismic data may be sorted according to the pile number of the target shot in the seismic exploration auxiliary data and the order of the pile number of the target geophone and the geophone code after the target seismic channel data corresponding to the target shot and the target geophone is determined from the at least two seismic data. For example, the pile number of the target shot point may be used as a first sort, the line number in the pile number of the target geophone point may be used as a second sort, the point number in the pile number of the target geophone point may be used as a third sort, the geophone point code of the target geophone point may be used as a fourth sort, and the target seismic trace data sequentially processed in the order from small to large in each sort may be sorted. In this way, whether the sequenced target seismic channel data determined from the at least two seismic data meets the specified condition can be judged subsequently, and the sequenced target seismic channel data is processed according to the judgment result, so that the processed target seismic channel data meets the specified condition.
Step S102: and judging whether the target seismic channel data determined from the at least two types of seismic data meet a specified condition, and processing the target seismic channel data according to a judgment result so that the processed target seismic channel data meet the specified condition.
In this embodiment, the specific condition may specifically include: the pile numbers and the demodulator probe codes of the target demodulator probes corresponding to the target seismic channel data determined from the at least two types of seismic data are different.
In this embodiment, it may be determined whether or not a plurality of target seismic-trace data determined from the at least two types of seismic data satisfy the specified condition. And if the judgment result is that the specified condition is met, the target seismic channel data can be reserved. If the judgment result is that the specified condition is not met, the target seismic channel data can be processed, so that the processed target seismic channel data meet the specified condition.
In this embodiment, if the determination result indicates that the specified condition is not satisfied, the processing of the target seismic channel data may specifically include, if a plurality of pieces of target seismic channel data determined from the at least two pieces of seismic data include specified seismic channel data in which at least two corresponding target geophone points have the same pile number and same geophone point code, performing superposition processing on each piece of specified seismic channel data to obtain new target seismic channel data corresponding to the target shot point and the target geophone point. Moreover, if the plurality of target seismic channel data determined from the at least two types of seismic data include designated seismic channel data in which at least two corresponding target geophone points have the same pile numbers and geophone point codes, the average amplitude value of each sampling point in each designated seismic channel data can be calculated respectively. The designated seismic channel data corresponding to the maximum average amplitude value may be used as new target seismic channel data corresponding to the target shot point and the target demodulation point.
For example, for a shot point on land, at a geophone position on land, the two acquisition systems are used to control the geophone at the geophone position to acquire seismic trace data, however, an acquisition system comprising wireless instruments typically controls the geophone to acquire real seismic trace data, while an acquisition system comprising wired instruments does not control the geophone to acquire seismic trace data. However, due to the requirements of the survey system design, to ensure record integrity, it is necessary to generate null data corresponding to the geophone at the location of the geophone point. Wherein, the amplitude value of each sampling point in the empty channel data is 0. Thus, two seismic data respectively acquired by an acquisition system comprising a wireless instrument and an acquisition system comprising a wired instrument are caused to have two corresponding seismic channel data with the same geophone code and pile number of the geophone, namely two repeated channels, one is real seismic channel data, and the other is null channel data, namely one is valued channel data and one is null channel data. For this situation, the two seismic channel data may be subjected to stacking processing to obtain new seismic channel data corresponding to the shot point and the geophone point. The average amplitude values of the sampling points in the two seismic channel data can be calculated respectively, and the seismic channel data corresponding to the maximum average amplitude value can be used as new seismic channel data corresponding to the shot point and the demodulator probe. Or, the generated empty track data can be directly removed. For example, fig. 2 and 3 are schematic cross-sectional views of two types of seismic data acquired by an acquisition system including a wireless instrument and an acquisition system including a wired instrument, respectively, in an embodiment of the present application. The abscissa of fig. 2 and 3 is the shot point stake number, the geophone point stake number, and the geophone point code, and the ordinate is the sampling time in milliseconds. Wherein the abscissa in fig. 2 and 3 is the same. As can be seen from fig. 2 and 3, there are both value tracks and zero tracks at the same abscissa positions in fig. 2 and 3.
Step S103: and generating a merged seismic gather corresponding to the at least two types of seismic data and aiming at the target shot point based on the processed target seismic trace data.
In this embodiment, generating, based on the processed target seismic trace data, a merged seismic trace set corresponding to the at least two types of seismic data and corresponding to the target shot point may specifically include sorting the processed target seismic trace data according to a pile number of the target shot point in the seismic exploration auxiliary data and an order of a pile number of the target geophone point and a geophone code, and using a seismic trace set formed by the sorted seismic trace data as the merged seismic trace set corresponding to the at least two types of seismic data and corresponding to the target shot point. For example, the pile number of the target shot point may be used as a first sort, the line number in the pile number of the target geophone point may be used as a second sort, the point number in the pile number of the target geophone point may be used as a third sort, the geophone point code of the target geophone point may be used as a fourth sort, and the target seismic trace data sequentially processed in the order from small to large in each sort may be sorted. After sorting, the channel numbers corresponding to the seismic channel data in the merged seismic channel set can be set according to the sorting order. FIG. 4 is a schematic cross-sectional view of a merged seismic gather derived based on the seismic data of FIGS. 2 and 3 in an embodiment of the present application. The abscissa of fig. 4 is the shot point stake number, the geophone point stake number, and the geophone point code, and the ordinate is the sampling time in milliseconds. As shown in FIG. 4, no clear trace data exists in the merged set of seismic traces.
In the method for merging seismic data, first, target seismic trace data corresponding to the target shot point and the target geophone point may be determined from the at least two types of seismic data based on the pile number and the shot code of the target shot point and the pile number of the target geophone point in the seismic exploration auxiliary data; wherein the shot code is used to characterize a type of seismic source located at the target shot location. Then, it may be determined whether target seismic channel data determined from the at least two types of seismic data satisfies a specified condition, and the target seismic channel data may be processed according to a determination result, so that the processed target seismic channel data satisfies the specified condition. Finally, a merged seismic gather for the target shot corresponding to the at least two types of seismic data may be generated based on the processed target seismic trace data. Therefore, the method for merging the seismic data can realize effective merging of the seismic data under the joint acquisition mode of the same shot point and the multiple types of detectors.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The apparatuses and modules illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.
For convenience of description, the above devices are described as being divided into various modules by functions, and are described separately. Of course, the functionality of the various modules may be implemented in the same one or more software and/or hardware implementations as the present application.

The computer software product may include instructions for causing a computing device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in the various embodiments or portions of embodiments of the present application. The computer software product may be stored in a memory, which may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, computer readable media does not include transitory computer readable media (transient media), such as modulated data signals and carrier waves.
