分层采油抽油泵
简 介：
分层采油抽油泵上、下泵同时工作，上泵利用上下两柱塞直径之差所形成的环形空间工作。上层油经偏心阀进入环形空间，然后经分流阀排出。下层油经下泵进油阀进入下泵筒，然后从下泵出油阀排出，经分流阀与上层油混合后一起排出地面。该泵用于多油层井中抽汲原油，可大幅度提高单井产量和 原油的采收率，降低生产成本，具有较高的综合经济效益。
The upper and lower pump will work at the same time, the upper pump will work using the annular space formed by the diameter difference between upper plunger and lower plunger. The upper oil enter into the annular space via eccentric valve, and then exhaust by the diverter valve. The lower oil, which enter into the pump barrel through the inlet valve of lower pump, and then exhaust through outlet valve of the lower pump, will discharge to the ground after the diverter valve mixed with the upper oil.
The pump is widely used for swabbing crude oil from multiple zone, which can greatly improve the single well production and oil recovery efficiency and reduce the production cost, has high comprehensive economic benefits.
