Rod-pumped well stop-free pumping and pump collision device

Abstract

The invention relates to a rod-pumped well stop-free pumping and pump collision device. The device comprises a supporting body, a beam hanger can be fixedly and slidably arranged on the supporting body in a sleeving mode, and when the beam hanger is fixedly arranged on the supporting body in a sleeving mode, the bottom end of the supporting body is lower than the bottom end of the beam hanger; a clamping structure capable of locking and unlocking the supporting body is arranged on the beam hanger; the device further comprises a top cylinder structure, the supporting body can move downwards along with the beam hanger, the bottom of the supporting body 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 clamping structure so as to unlock or reset and lock the clamping structure; and a first step part is arranged at the top of the supporting body, and when the beam hanger is fixedly arranged on the supporting body in a sleeving mode, the distance between the top face of the beam hanger and the first step part is larger than the anti-impact distance of an oil well pump. The device realizes stop-free pumping and pump collision of a rod-pumped well, shortens the pump collision operation time, improves the working efficiency, eliminates the damage of pump collision measures to a polish rod, avoids the safety risk in the operation process, and better serves oil field production.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a non-stop pumping device for pumping wells. 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 wells, the pumps are affected by substances such as sand and wax, and the pumps often fail due to the failure of the pump valve to close tightly, which affects the production of the oil wells. . [0003] The most simple and effective solution on site is to take the measure of "touching the pump" to restore the normal operation of the oil well pump, that is, to reduce the downward anti-shock distance of the oil well pump by lifting the clamp (lower light rod) and bumping the valve cover with the plunger of the oil well pump. The generated vibration makes the sand and wax adhered to the valve ball and seat fall off. The operation process of "touchi...

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
