Description

Technical Field

[0001] The invention relates to the technical field of oil drilling, in particular to a pipeline crossing drilling while drilling gyro shock absorbing device and drilling equipment. Background Art

[0002] There are some special wells that need to be re-entered, such as deep wells, rescue wells, gas storage plugging wells, and abandoned wells. They need to enter the original wellbore for other operations. This type of well requires very precise construction parameters. According to existing technologies, the original well trajectory measured by magnetic instruments such as MWD (measurement while drilling) and magnetic guidance tools is usually interfered by magnetic materials in the wellbore or formation, affecting the measurement results, resulting in a large deviation between the collected data and the actual wellbore trajectory. The gyro inclinometer can sense the angular velocity of the earth's rotation, is not affected by magnetic interference, and accurately measures the well inclination and azimuth in a strong magnetic environment and in oil casing or drill pipe. The gravity high side, the gyro inclinometer automatically seeks north, no north correction is required, and the measured data is the true north azimuth data of the wellbore trajectory. It can be used directly without correction. The integration of the gyroscope and the magnetic probe is the only way to judge the degree of interference of the magnetic tool face angle in a magnetic interference environment. It is a necessary technical means for re-entry into old wells and collision prevention of adjacent wells. The wellbore trajectory is continuously re-measured at multiple points using a high-precision gyroscope, and then a magnetic guidance tool is lowered to compare the two measurement results and continuously adjust subsequent directional trajectory parameters.

[0003] When conducting gyro measurement while drilling, fiber optic gyroscopes, mechanical gyroscopes and solid-state gyroscopes are mostly used. Fiber optic gyroscopes have poor seismic resistance. Gyro devices are large in size, and it is difficult to miniaturize the measuring instrument. The future development trend is to use advanced mechanical gyroscopes and solid-state gyroscopes to replace fiber optic gyroscopes to improve seismic resistance and miniaturize the instrument. At present, when using gyroscopes for measurement, dynamically tuned gyroscopes are used. Dynamically tuned gyroscopes refer to gyroscopes whose rotors are supported by flexible joints composed of two pairs of orthogonal torsion bars and a balance ring frame. The negative elastic torque generated by the dynamic effect is used to offset the positive elastic torque of the elastic torsion bar, so that the rotor is in a free rotor state without torque, which improves the accuracy of the gyroscope. Dynamically tuned gyroscopes are non-liquid floating, dry elastically supported, electromechanical flexible gyroscopes. As a mature rigid rotor gyroscope, its accuracy range is between 0.01° / h and 1° / h. The dynamically tuned gyroscope, also known as the dynamic tuning gyroscope, has the advantages of simple structure, small size, light weight and low cost. It is widely used in military and civilian fields such as aviation, navigation, missiles, spacecraft, guidance and navigation systems, and oil field exploration and development. Compared with the flight field, the application of gyroscopes in the field of drilling has higher technical requirements and stronger product adaptability, because its working conditions are harsh, especially vibration has a great impact on the gyroscope measurement accuracy. The existing technology uses gyroscopes while drilling for drilling measurement. The shock absorption protection effect is insufficient, which is easy to affect the measurement results. In addition, the gyroscope is in vibration for a long time, which is easy to cause the instrument to be damaged by vibration. Summary of the invention

[0047] On the basis of the above scheme, each of the sliding limiting mechanisms includes a rotating plate 7, a connecting plate 14, a telescopic sleeve 9 and a sliding rod 10, the rotating plate 7 is fixed on the outer wall of the module tube 6 or the main shock absorbing sleeve 1, the connecting plate 14 is fixed on the outer wall of the main shock absorbing sleeve 1 or the auxiliary shock absorbing sleeve 3, one end of the telescopic sleeve 9 is rotatably connected to the rotating plate 7, the other end of the telescopic sleeve 9 has a sliding hole, one end of the sliding rod 10 passes through the sliding hole and is slidably arranged in the telescopic sleeve 9, and one end of the sliding rod 10 is provided with a sliding block with a cross-sectional size larger than the cross-sectional size of the sliding hole, and the other end of the sliding rod 10 is detachably connected to the connecting plate 14.

[0048] The telescopic sleeve 9 and the sliding rod 10 can slide relative to each other to achieve telescopic Figure 7 As shown, the slider and the sliding hole are limited, thereby limiting the maximum extension distance of the telescopic sleeve 9 and the sliding rod 10 to prevent them from being disengaged. When assembling the pipeline passing through the drilling gyro shock-absorbing device, the other end of the sliding rod 10 is separated from the connecting plate 14, and the telescopic sleeve 9 and the sliding rod 10 are rotated and lifted around the rotating plate 7.

[0061] The assembly process of the gyro shock-absorbing device for pipeline crossing drilling is as follows: first install the gyro barrel 2 at the bottom of the damping column 17 of the main shock-absorbing sleeve 1, then install the gyro body 22 in the shock-absorbing sponge 21 of the gyro barrel 2, extend the gyro connector 20 out of the gyro barrel 2, and connect it through the free space inside the main shock-absorbing sleeve 1, then connect and fix the top of the damping column 17 of the auxiliary shock-absorbing sleeve 3 to the gyro barrel 2, and slide the auxiliary shock-absorbing sleeve 3 to the lower end of the gyro barrel 2. Then install the module barrel 6 on the top of the main shock-absorbing sleeve 1 through the mounting block 18 (the mounting block 18 and the connecting block 5 are tightened by threads), and connect the internal equipment of the module barrel 6 to the power connector 19, and finally lower each telescopic sleeve 9 and the sliding rod 10, and fix the sliding rod 10 on the connecting plate 14 through the fixing bolt 12 and the fixing nut 13.

The gyroscope tube 2 slides up and down in the main shock-absorbing sleeve 1 as the damping column 17 expands and contracts. At the same time, the internal shock-absorbing sponge 21 absorbs the remaining vibration, reduces the vibration transmitted to the gyroscope body 22, and protects the gyroscope body 22.
