[0002] During oil and gas drilling, well control pressure testing is an important device for controlling the high-pressure oil and gas flow in the well, and is an important guarantee for ensuring the safe and smooth implementation of drilling and development operations. After the staff has completed the relevant work in the pressure testing pit, they withdraw from the pressure testing pit and then start the pressure testing work. Obviously, the safety protection device plays an important protective role.
[0003] After searching, the patent number CN215718600U proposed a safety protection device for well control pressure testing. The water leakage detector judges that the water pipe starts to leak through the sound of water leakage. At this time, the electric telescopic rod starts to start, the electric telescopic rod extends to drive the moving block to move up, the moving block push rod 1 moves up, the push rod 1 drives the slider to slide inward, the sliding of the slider drives the two push rods 2 to move inward at the same time, and the two push rods 2 drive the grippers to move inward at the same time, thereby effectively fixing the water pipe to prevent the water pipe from being separated from the blowout preventer due to excessive pressure, causing harm to the staff.
[0004] However, the structure of the fixing device for the water pipe is relatively complex, and the contact area between the gripper and the water pipe is relatively small, resulting in an insufficient support effect on the water pipe; secondly, when there is a sound of water leakage, the leakage may be more serious, and the water leakage detector is not sensitive enough to judge the water pipe leakage through the sound of water. Therefore, a safety protection device for well control pressure test is proposed to improve the above shortcomings. Utility Model Content

[0030] Working principle: When the water pipe starts to leak, the absorbent cotton 211 will absorb the water on the water pipe. When the sensor 212 senses the leakage on the absorbent cotton 211, it will send a signal to the drive motor 111, start the drive motor 111, rotate the first gear 112 and the second gear 113, and rotate the screw rod 130 at the same time, so that the upper clamping plate 140 and the lower clamping plate 150 move toward the water pipe at the same time until the water pipe is fixed to prevent the water pipe from falling off when the water pressure is too high.
