Description

Integrated Blade Hydraulic-Magnetic Transmission Wellbore Cleaning Tool

technical field

The invention relates to a wellbore cleaning tool used in order to effectively suppress the formation of cuttings beds and improve the wellbore cleaning efficiency during the drilling process of oil and gas wells, in particular to an integrated blade hydraulic-magnetic transmission wellbore cleaning tool.

Background technique

At present, well types such as high-inclination wells, horizontal wells, and extended-reach wells are often used in the exploitation of offshore oil, natural gas, and shale gas to increase the drainage area of the wellbore and maximize the production of a single well. Due to the existence of the build-up section (the curved well section whose inclination angle increases from 0° to 90°) and the horizontal well section in these well types, the cuttings are not easily carried out of the wellbore by the drilling fluid under the action of the gravity component, and cuttings appear. The accumulation phenomenon forms the cuttings bed. Both field experience and indoor theoretical experiments show that the cuttings bed is easy to be found in highly deviated well sections (generally refer to the build-up section between 45° and 90°) and horizontal well sections (with an inclination angle of 90° °) formed between. If the sedimentary cuttings bed thickness in the well is too high, it will lead to a series of serious downhole problems, such as increased frictional resistance and torque of the drilling tool, and even serious downhole accidents such as pipe sticking and twisting of the drilling tool. Dealing with these downhole accidents will Significantly reduce ROP, greatly increase non-production time and operating costs. This requires that during the drilling process of this type of well, a high cuttings cleaning efficiency should be maintained, and necessary methods should be adopted in well sections where cuttings beds are easy to form to prevent the formation of cuttings beds and ensure that the drilling tools and the well eye safe.

In view of the difficulty in cutting cuttings cleaning in high-inclination and horizontal sections, the following five methods are generally used to clean cuttings in the drilling site, including: increasing the drilling fluid return rate, improving the rheological properties of the drilling fluid, and shortening the drilling tool length. , increase the drill pipe rotation speed, and use the wellbore cleaning tool to transmit torque through the drill pipe.

1. Improve drilling fluid return speed

The higher the average return velocity of the drilling fluid in the borehole annulus, the more favorable it is to remove cuttings. However, high return speed has high requirements on drilling equipment, and the corresponding power cost is also high. At the same time, for some soft formations, high return velocity may cause serious wellbore collapse accidents. Therefore, due to the limitation of equipment and formation, increasing the return rate cannot completely solve the problem of wellbore cleaning.

2. Improve rheological properties of drilling fluid

The method reduces the fluidity index of the mud, increases the dynamic-plastic ratio, improves the rock-carrying performance of the drilling fluid, and enhances its suspension carrying capacity. The disadvantage of this method is that to improve the performance of drilling fluid, additional drilling fluid admixture needs to be added, which increases the cost. At the same time, the higher dynamic-plastic ratio will also bring a greater burden to surface equipment such as pumps and increase power consumption. This method alone often has limited effect and must be combined with other methods.

3. Short tripping and tripping drilling tools

Under the existing conditions, in addition to improving the rock-carrying capacity by increasing the mud return velocity and improving the mud performance, it is necessary to cooperate with short-range tripping, segmented circulation, and back reaming in actual drilling to destroy and remove the rock. crumb bed. Therefore, for the well section where the debris bed deposition is not serious, the method of short tripping can be adopted. For the well type and well section where the cuttings bed is easy to form, during the short tripping process, the drilling tool below the kickoff point moves along the lower hole wall, which can destroy the cuttings bed. For the severe cuttings bed, the cuttings bed can be destroyed by back reaming for wells where the effect of short tripping is not obvious. Although adopting the short tripping and cleaning method can play the effect of clearing debris, it will take a lot of time to trip and trip, which has a strong impact on the efficiency of drilling.

4. Increase the drill pipe speed

Increasing the drill pipe speed during drilling can increase the peripheral velocity of the drilling fluid near the surface of the drill pipe, so that cuttings can be better suspended to the high side of the wellbore, and the cleaning efficiency of cuttings can be improved to a certain extent. However, in the deflection section (inclination angle 0-90°) where drilling cuttings is difficult to clean, downhole power drilling tools (screw drills and turbine The angle remains unchanged, the drill pipe and the housing including the downhole drilling tool do not rotate, and only the drill bit rotates to break the rock. However, since the drill pipe as a whole does not rotate, it is not possible to remove the cuttings bed by increasing the speed of the drill pipe.

5. Wellbore cleaning tool using drill pipe to transmit torque

Another way to suppress the formation of cuttings beds in highly deviated and horizontal wells is to use a bladed cuttings cleaning tool that is threaded to the drillpipe, which rotates while transmitting torque to the well Eye cleaning tools and cuttings cleaning tools suppress the cuttings bed with the rotation of the drill pipe, but the disadvantage is that the rotational power of the tool comes from the drill pipe. When creating inclined sections, downhole power drilling tools (turbo drilling tools, screw drilling tools) should be used for sliding drilling When drilling, this type of tool cannot rotate because the drill pipe does not rotate, and basically has no effect on inhibiting the formation of cuttings beds.

Contents of the invention

The purpose of the present invention is to provide an integrated blade hydraulic-magnetic transmission wellbore cleaning tool, which is used to solve the current problems in wells such as highly deviated wells, horizontal wells, and extended-reach wells.

1. The present invention is driven by hydraulic-magnetic coupling and is not limited by whether the drill pipe is rotating or not.
