Non-stop pumping device for pumping rig well

Abstract

The invention relates to a pumping device for pumping rigs without stopping and touching the pump. The end is lower than the bottom end of the hanger; the hanger is provided with a locking structure that can lock and unlock the support body; the device also includes a top cylinder structure, the support body can move down with the hanger and the bottom of the support body It can abut against the top of the top cylinder structure, and the top of the top cylinder structure can abut against the bottom of the locking structure to unlock or reset the locking structure; the top of the support body is provided with a first step part, and the rope hanger is fixedly sleeved When on the support body, the distance between the top surface of the rope hanger and the first step portion is greater than the anti-shock distance of the oil well pump. The device realizes the pumping well without stopping the pumping, shortens the operating time of the pumping, improves the work efficiency, eliminates the damage to the polished rod caused by the pumping measures, avoids the safety risks in the operation process, and better serves the oilfield production.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas exploitation, in particular to a stop-free pumping device for a pumping unit well. Background technique [0002] At present, more than 95% of the oil wells in the oil field use pumping units to produce oil. During the production process of the pumping unit, the oil wells are affected by substances such as sand and wax, and the oil wells are often leaked due to the failure of the pump valve to close tightly, which affects the output of the oil wells. . [0003] The most simple and effective solution at the scene is to take the measures of "touching the pump" to restore the oil well pump to normal operation, that is, reduce the downward anti-shock distance of the oil well pump by lifting the square clip (lowering the polished rod), and use the oil well pump plunger to collide to fix the valve cover, The resulting vibration causes the sand and wax adhering to the valve ball and valve sea...

AI Technical Summary

Problems solved by technology

When "touching the pump", two experienced employees need to work together for more than 30 minutes. The clamping teeth of the square clip will cause damage to the polished rod, which will increase the failure of the polished rod and the oil leakage of the packing, which will affect the production rate of the oil well. There are also certain safety risks in the operation process, and hand clamping accidents between square clips and rope hangers often occur
