[0002] The wireless logging-while-drilling inclinometer is an essential measuring instrument in the construction of directional wells and horizontal wells. It measures parameters such as the well inclination angle, azimuth angle, and tool face angle at the bottom of the well through sensors, and uses a wireless transmission method to transmit the measurement data to the ground in real time. By adjusting the wellbore trajectory in a timely manner, it ensures that the drill bit drills in the designed direction of the wellbore trajectory and reaches the target formation smoothly. However, during use, in the long-term use of the wireless logging-while-drilling inclinometer, the performance of the devices and electronic circuits in the instrument will change, resulting in a deterioration of the measurement accuracy of the wireless logging-while-drilling inclinometer, thereby affecting the construction quality of directional construction.

[0003] The overall structure of the existing wireless logging-while-drilling inclinometer calibration device is relatively large, resulting in extremely inconvenient carrying. At the same time, the calibration work has high requirements for accuracy. If it is frequently disassembled for carrying, not only will the work efficiency be affected, but also the calibration quality cannot be guaranteed.

[0004] Therefore, aiming at the problem that the overall structure of the existing wireless logging-while-drilling inclinometer calibration device is relatively large, resulting in extremely inconvenient carrying, a wireless logging-while-drilling inclinometer calibration device that is convenient to carry can be designed to store the calibration device for convenient carrying.

Specific embodiments

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figures 1 - 4 , the present utility model provides an embodiment: a portable wireless MWD inclinometer calibration device, including a base 1, and further including a mounting seat 4. A turntable 2 is provided at the upper end of the base 1. A rotating groove is opened on the upper end surface of the base 1. The rotating groove and the turntable 2 are sleeved. The lower end of the turntable 2 is rotationally connected to the bottom of the rotating groove through a connecting shaft. A connecting seat 3 is fixedly connected to the upper end surface of the turntable 2. Support frames 5 are rotationally connected to both the left and right ends of the connecting seat 3 through connecting shafts. Rotating shafts 6 are fixedly installed at both the left and right ends of the mounting seat 4. One end of each of the two rotating shafts 6 away from the mounting seat 4 is rotationally connected to the upper end of the support frame 5 through a bearing seat. A positioning sleeve 7 is fixedly connected to the upper end of the mounting seat 4. An adjusting pipe 71 is provided at the lower end of the mounting seat 4. A locking seat 8 is fixedly installed at one end of the positioning sleeve 7 away from the mounting seat 4. A locking seat 8 of the same kind is fixedly installed at one end of the adjusting pipe 71 away from the mounting seat 4. One end of the rotating shaft 6 away from the mounting seat 4 extends to the outside of the support frame 5 and is fixedly installed with an adjusting disk 9. An mounting plate 10 is fixedly installed at the upper end of the surface of the support frame 5. Positioning plates 11 are fixedly connected to both the left and right sides of the upper end of the turntable 2. By using the rotational connection between the support frame 5 and the connecting seat 3, the mounting seat 4 can be flipped onto the base 1 to achieve storage and facilitate carrying.

[0022] Please refer to Figure 1 and Figure 2, in this embodiment, a limit bolt 41 is threadedly mounted on the surface of the mounting base 4. There are two limit bolts 41 symmetrically arranged on the front and rear sides of the mounting base 4. The ends of the two limit bolts 41 are in fitting connection with the surface of the adjusting pipe 71. The upper end of the adjusting pipe 71 is sleeved with the mounting base 4, and the upper end of the adjusting pipe 71 extends into the inner side of the positioning sleeve 7 and is slidably connected to the positioning sleeve 7. Locking bolts are threadedly mounted at both the front and rear ends of the surface of the locking seat 8. A through hole is formed on the surface of the locking seat 8, which penetrates the locking seat 8 from top to bottom, and the inner diameter of the through hole is adapted to the adjusting pipe 71. The adjusting pipe 71 can move in the positioning sleeve 7 to adjust the overall length between the adjusting pipe 71 and the positioning sleeve 7, improving flexibility. At the same time, when storing, the adjusting pipe 71 is retracted into the positioning sleeve 7, which is convenient for storage.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4 , in this embodiment, a scale is provided on the surface of the adjusting disc 9. The mounting plate 10 is designed in an L-shaped structure. A positioning bolt 101 is threadedly mounted at the upper end of the mounting plate 10, and the end of the positioning bolt 101 is in fitting connection with the adjusting disc 9. During calibration, the operator can rotate the adjusting disc 9 to drive the mounting base 4 to rotate, adjust the inclination during calibration, and use the positioning bolt 101 to limit the adjusting disc 9 to increase the stability during calibration.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, a plug rod 111 is slidably mounted at the upper end of the positioning plate 11. One end of the plug rod 111 extends outside the positioning plate 11 and is fixedly connected to a movable handle 112. A connecting spring 113 is sleeved on the outside of the plug rod 111, and both ends of the connecting spring 113 are fixedly connected to the positioning plate 11 and the movable handle 112 respectively. A plug hole 114 is formed at the lower end of the surface of the support frame 5, and the other end of the plug rod 111 is inserted into the plug hole 114. By inserting the plug rod 111 into the plug hole 114, the support frame 5 can be limited. Thus, when storing, the operator moves the movable handle 112 to move the plug rod 111 outside the plug hole 114, and the support frame 5 can be flipped to fit the mounting base 4 to the base 1, which is convenient for the storage and carrying of the whole device. When in use, the support frame 5 is flipped up, the mounting base 4 is in a vertical state, and the plug rod 111 enters the plug hole 114 to achieve limit fixation.

[0025] When working, the wireless measurement-while-drilling inclinometer with verification is installed and fixed through the mounting base 4. The locking seats 8 on both sides facilitate the fixation of both ends of the wireless measurement-while-drilling inclinometer. The adjusting tube 71 moves within the positioning sleeve 7. By adjusting the position of the adjusting tube 71, the overall length is changed, improving flexibility and facilitating the verification work. During verification, the operator can rotate the adjusting disc 9 to drive the mounting base 4 to rotate, adjust the inclination during verification, and use the positioning bolt 101 to limit the adjusting disc 9 to increase the stability during verification. When not in use, the operator moves the movable handle 112 to move the pin rod 111 to the outside of the pin hole 114, and the support frame 5 can be flipped to fit the mounting base 4 to the base 1, facilitating the storage and carrying of the overall device. When in use, the support frame 5 is flipped up, the mounting base 4 is vertical, and the pin rod 111 enters the pin hole 114 to achieve limit fixation.

[0026] Through the above steps, during carrying, it can be folded and stored without disassembly, which is convenient for carrying, ensures work efficiency and verification accuracy, and improves practicality to solve the problem that the overall structure of the existing wireless measurement-while-drilling inclinometer verification device is relatively large, resulting in extremely inconvenient carrying.
