Description

Position detection device for snubbing machine

technical field

The utility model relates to a position detection device for a snubbing operation machine.

Background technique

At present, facing the depletion of oil and gas resources, it is more and more urgent to tap the potential of oilfield production and treat abandoned wells, engineering accident wells, and stop production wells to tap the potential to resume production or increase production. The market demand for snubbing equipment is increasing year by year.

The currently used snubbing operation machine is mainly controlled by manual multi-way valves to control the lifting of the tubing and the slip switch. There are two operating processes, one is to lower the tubing operation, and the other is to lift the tubing. The tubing is made of multiple The oil pipes are connected in series, and there is a coupling in the middle. When lifting and lowering the oil pipes, the oil pipe couplings must be passed. As shown in Figure 1, take the following oil pipe discharge operation process as an example: the floating slip 101 is raised to the position, the oil pipe 102 is installed, the floating slip 101 clamps the oil pipe 102, and then the lower gate 110 is closed, and the discharge is lifted shortly. The pressure in the joint 107 opens the upper ram 109, the floating slip 101 clamps the oil pipe 102 and moves downward, and when the oil pipe coupling 103 reaches the middle position of the rising nipple 107, closes the upper ram BOP 105, Open the balance valve 106 to replenish pressure, then open the lower ram BOP 108, the floating slip 101 clamps the oil pipe 102 and lowers it to the right position, so that the oil pipe coupling 103 passes through the lower ram BOP 108 smoothly, and then fixes the slip 104 clamp Tighten the oil pipe 102, open the traveling slips 101, and the traveling slips 101 are raised to the right position, completing a cycle. Lifting tubing operations are similar. As mentioned above, there is a process of passing the coupling during the lifting and lowering of the tubing, and the position of the coupling is judged manually in this process, so there is a long section of the raised sub-joint in the middle to ensure , there will be no misoperation and oil pipe couplings colliding with the upper and lower ram BOPs to cause premature damage to the BOP seals, and there is a process of pressure relief between the upper and lower ram BOPs (when passing through the couplings), if the middle If the raising nipple is too long, the time to complete this process will also increase, reducing the speed of operation. The traditional visual method has high requirements on the operator and high concentration, the operator is prone to fatigue, and the distance between the upper and lower ram BOPs is large, and the amount of discharge and replenishment fluid is large, resulting in waste of resources.
