AI Technical Summary
Well blowouts are prone to occur when there is pressure at the wellhead, leading to engineering accidents. At the same time, the clearance of the oil pump affects the pump efficiency. Existing measures such as increasing the pump hanger depth or well control operations are not effective, increasing costs and risks.
The design incorporates a blowout-proof, gapless oil pump with a single-flow valve structure and sealing device to ensure that fluid can only flow from bottom to top. High-density heavy oil is injected through the storage pipe and plug joint to eliminate gaps and prevent blowouts and gas from affecting pump efficiency.
It achieves blowout-free operation when pumping down a high-pressure oil well, avoiding oil layer contamination, improving pump efficiency, reducing safety risks and production costs, and meeting environmental protection requirements.
