Technical Field

[0002] Casing deformation is a common problem in the oil drilling process and may cause serious damage to downhole operations. Casing deformation is usually caused by unbalanced downhole pressure, formation movement, well wall collapse and other reasons. When the casing is deformed, the passage of the drill bit is hindered, resulting in the inability to smoothly carry out drilling or other downhole operations. At the same time, casing deformation may destroy the sealing of the wellbore, causing oil and gas leakage, increasing the risk of blowout, and threatening on-site safety. In addition, casing deformation will also affect the subsequent oil production process and reduce the service life of the oil well. Summary of the invention

[0031] In a specific embodiment, the tool is lowered into the well through the drill string, and low-flow drilling fluid is introduced. The drilling fluid first passes through the guide ring 3 for diversion. The drilling fluid changes its trajectory through the guide wheel 5, drives the turbine 7 to rotate, generates power, and the turntable 15 starts to rotate at a speed of 15r / min. At this time, the centrifugal force generated by the centrifugal block 17 is not enough to overcome the pulling force of the centrifugal spring 16. The centrifugal spring 16 is at its original length, the centrifugal block 17 does not cooperate with the centrifugal block buckle 1901, and the power cannot be transmitted to the spline sleeve 20.

When the casing is found to be deformed, the ground staff increases the drilling fluid flow rate. At this time, the speed of the turbine 7 increases, the speed of the turntable 15 increases, and the speed is 60r / min. The centrifugal force generated by the centrifugal block 17 overcomes the pulling force of the centrifugal spring 16. The centrifugal block 17 cooperates with the centrifugal block buckle 1901 to transmit the power of the turntable 15 to the spline sleeve 20. The roller 23 is initially located at point A of the cam. The impact spring 37 is in a compressed state. The power of the spline sleeve 20 is transmitted to the cam 24, and the cam 24 rotates to point B. The impact spring 37 is released, and the impact hammer 36 hits the repair push block 38, so that the repair push block 38 extends and hits the deformed part of the pipe wall. The cam 24 rotates, and the impact hammer 36 reciprocates to hit the repair push block 38 to perform casing repair work. The camera detects the shape of the pipe wall in real time, and the control unit 32 transmits the information to the ground. If the ground personnel believe that the pipe wall shape meets the requirements, they can choose to reduce the drilling fluid flow rate, find the next deformation position, or lift the drill string recovery tool.

The intelligent impact casing shaping tool according to claim 1 is characterized in that: Lubricating oil is applied between the guide wheel string bearing (6) and the guide tube string bearing (10), a sealing ring is placed on the upper end of the guide wheel string bearing (6), and a sealing ring is placed between the bearing end cover (9) and the guide tube (12) to ensure a lubricated environment inside the bearing.

3. The intelligent impact casing shaping tool according to claim 1 is characterized in that: The maximum extension distance of the repair push block (38) should be 2-3 mm greater than the pipe diameter, so as to improve the repair effect of casing deformation.

4. The intelligent impact casing shaping tool according to claim 1 is characterized in that: The MCU selected is STM32H743ZI with a temperature tolerance range of -40℃~+105℃. The camera selected is TCM8230. An 8-bit parallel DVP interface is used to transfer image data to STM32H743ZI. STM32 configures GPIO and DMA to store image data in SRAM in frames, minimizing CPU participation to achieve efficient collection. The wireless transmission chip selected is SX1278. Its low power consumption characteristics can ensure a long working time. It is connected to the MCU through an SPI interface, and the fill light uses LED.

5. The intelligent impact casing shaping tool according to claim 1 is characterized in that: The centrifugal block (17) is provided with a centrifugal block limiter (1702), and the rotating disk (15) is provided with a hinge seat limiter (1501). When a large flow of drilling fluid is introduced, the rotating disk (15) rotates at a high speed, and the centrifugal block limiter (1702) cooperates with the hinge seat limiter (1501) during the movement to prevent the centrifugal spring (16) from being over-stretched and damaged. Under the action of the hinge seat limiter (1501), the maximum distance of movement of the centrifugal block (17) just cooperates with the centrifugal block buckle (1901) to achieve power transmission.
