Description
Technical Field
The invention relates to the technical field of oil and gas field drilling, in particular to an intelligent starting method and system for functions of an oil and gas field drilling tool.
Background

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of an intelligent starting method of a drilling tool function of an oil and gas field according to an embodiment of the present invention. The embodiment of the invention provides an intelligent starting method for the functions of an oil-gas field drilling tool, which comprises the following steps:
S100, placing drilling tools according to preset postures by field operators;
s110, measuring and collecting current attitude signals of the drilling tool by a sensor;
S120, the processor calculates a current gesture signal to obtain a current gesture sequence of the drilling tool;
S130, the processor compares the current gesture sequence of the drilling tool with a preset gesture sequence, and when the current gesture sequence of the drilling tool is consistent with the preset gesture sequence, the processor starts the function of the drilling tool.
For example, in the conventional technology, a downhole dynamics acquisition tool powered by a battery can measure and store data such as acceleration, rotation speed, temperature and the like of a triaxial of a drilling tool, but the battery power and the memory capacity are limited, the drilling tool can acquire useless data and information if not performing drilling operation, and the downhole dynamics acquisition tool is in an operating state for a long time, so that the battery power is excessively lost. Therefore, effective management of battery power and memory capacity is a necessary condition to ensure proper operation of the downhole dynamics acquisition tool.
The downhole dynamics acquisition tool has a real-time clock that can track time, and when it begins to acquire and record data, it must be programmed to set an estimated time that is the same as the estimated time of the start of data acquisition. After completing the programming set-up operation, the operator assembles the downhole dynamics acquisition tool into a drilling tool and delivers it to the drilling site. Multiple incidents will lead to delays in drilling operations of hours or even weeks. The downhole dynamics acquisition tool is awakened by programming set by an operator, and after the estimated data acquisition start time is reached, the downhole dynamics acquisition tool records sensor data of drilling operation of the drilling tool at a well site. To prevent this, the operator must disassemble the downhole dynamics acquisition tool, reprogram the data acquisition start time, and then assemble into the drilling tool. In this process, the disassembly and assembly operations use special tools installed at the drilling site and are performed on site by trained operators. It may even be necessary to transport the tool back to the maintenance shop for this operation, which requires additional personnel, expense and time, severely impacting the efficiency of the drilling operation, further increasing production costs.
After the method is adopted, in a drilling site, an operator firstly puts a drilling tool to a preset gesture (such as horizontal-vertical-horizontal) according to drilling requirements, then a measuring sensor is arranged on the drilling tool, gesture signals of the drilling tool are collected by the measuring sensor, noise signals are filtered and amplified through a signal processing circuit, and then the gesture signals are resolved through a main control processor to obtain a real-time gesture sequence of the drilling tool. When the master control processor determines that the real-time pose sequence of the drilling tool corresponds to the pre-set pose sequence, certain functions of the drilling tool are initiated or preprogrammed operations are performed. The process avoids the assembly and disassembly of the drilling dynamics tool on the drilling site, saves key resources and time, improves the production efficiency of drilling operation, and saves the production cost.
After the measuring sensor is mounted on the drilling tool, the three-axis mounting direction of the sensor is shown in fig. 2 (a). A schematic top view of the rotational direction of the field drilling tool is shown in fig. 2 (b).
In embodiments of the present invention, the functions of the drilling tool initiated by the master control processor are not limited to performing certain control operations in the tool, waking up the system, initiating fast data acquisition, initiating power to the functional circuitry, initiating depassivation operations of the battery, adjusting tool parameters, and the like.
In one possible embodiment, the processor further determines whether the maintenance time of each attitude of the drilling tool reaches a predetermined maintenance time after determining that the current attitude sequence of the drilling tool is consistent with the preset attitude sequence, and activates the function of the drilling tool when the maintenance time of the current attitude sequence reaches the predetermined maintenance time.
For example, a maintenance time requirement may be set for each attitude of the drilling tool, for example, when drilling operation is to be started, n attitude positions are set according to a pre-required drilling site, the time required to be maintained for each attitude position is D1, D2...dn, and the time required to be maintained for each preset attitude position is T1, T2..tn. Only when the posture maintaining time D1 of the on-site placement of the drilling tool is greater than or equal to the preset posture maintaining time T1 requirement, the posture maintaining time D2 is greater than or equal to the preset posture maintaining time T2. If the maintenance time of any one of the gestures does not meet the corresponding maintenance time requirement, the measuring sensor continuously collects the gesture signal of the drilling tool.
In one possible embodiment, the attitude data includes triaxial gravitational acceleration, well inclination angle, toolface angle, rotational speed.
Illustratively, attitude signals of the drilling tool such as triaxial gravity acceleration, rotational speed and the like are all acquired by a measuring sensor, and are solved by a main control processor to obtain an attitude sequence of the drilling tool. The well bevel angle and the tool face angle are calculated by the main control processor according to the triaxial gravity acceleration.
The triaxial gravity acceleration is G X、GY、GZ respectively, and the calculated well inclination angle theta and the tool face angle alpha are respectively:
The embodiment of the invention also provides an intelligent starting system for the functions of the drilling tool of the oil-gas field, as shown in fig. 3, the system comprises:
the measuring sensor is arranged on the drilling tool and is used for measuring and collecting current attitude signals of the drilling tool;
the main control microprocessor is used for resolving the current gesture signal to obtain a current gesture sequence of the drilling tool, comparing the current gesture sequence with a preset gesture sequence, and starting the function of the drilling tool when the current gesture sequence is consistent with the preset gesture sequence;
And the data storage module is used for storing the current gesture sequence of the drilling tool, the related information and data of the tool start and reading the recovered data of the tool.
Illustratively, the measuring sensor may employ one triaxial gravitational acceleration sensor or three independent gravitational acceleration sensors.
In addition to the measurement sensor and the master control processor, the system further comprises a power supply circuit, a clock circuit, a signal conditioning circuit and a master control processor circuit, wherein the power supply circuit is used for supplying power to the measurement sensor, the master control microprocessor and the data storage module, and the clock circuit is used for providing clock frequency. The signal conditioning circuit is located between the measuring sensor and the main control processor, and the memory is connected with the main control processor. The measuring sensor is arranged in the drilling dynamics tool and is used for measuring the current gesture of the drilling tool, and the main control processor circuit converts a gesture signal of the current drilling tool from an analog quantity into an electric signal which is easy to process and decode and transmits the electric signal to the signal conditioning circuit. The signal conditioning circuit is mainly used for carrying out filtering, amplifying and other processing on the gesture signals output by the measuring sensor, and is convenient for the main control processor to accurately calculate the gesture signals of the current tool, so that the well inclination angle and the tool face angle of the tool are calculated.
The master processor and the memory may employ hardware circuits with the master microprocessor as a core. The master microprocessor includes, but is not limited to, a DSP (DIGITAL SIGNAL Processing) processor, ARM (Advanced RISC Machine) processor, PLC (Programmable Logic Controller) processor, or FPGA (Field Programmable GateArray) processor.
Downhole drilling tools are in a state of drilling operations that mainly include loading the drilling tool into a conveyance system, assembling the drilling tool into a downhole tool assembly (BHA) system, pumping drilling fluid by the drilling tool, rotating the drilling tool, causing a degree of shock and vibration to the drilling tool, causing a degree of stick-slip to the drilling tool, and causing a change in direction and attitude of the drilling tool.
In an embodiment of the invention, the measurement sensor includes a three-axis acceleration sensor, a three-axis magnetometer, a gyro sensor, and a flow meter.
In the embodiment of the invention, the triaxial acceleration sensor adopts a multi-sensor combination to measure the earth gravity field and perform attitude calculation.
Illustratively, the present invention employs a multi-sensor assembly for attitude measurement due to the large design and resolution difficulties associated with solely using an acceleration sensor to measure the gravitational field due to vibration and noise interference during drilling operations.

It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
