世界上许多石油公司、科研单位都在研究、试验更先进的采油方法，特别是注水驱油油田．中期注水机械采油是主要研究项目之一。本文介绍螺杆泵在高含水条件下试采三年的结果。解决试采中出现的问题，最后与游渠泵、潜油电泵比较机械效率，结果是螺杆泵比上述二泵效率分别高13％、50％。 Many oil companies and research institutes all over the world are researching and testing more advanced oil recovery methods, especially waterflooding oilfields. Medium-term water injection machinery oil production is one of the major research projects. This article describes the screw pump in high water conditions trial mining three years results. Solve the problem occurred in the trial mining, and finally the drainage pump, submersible pump compared to mechanical efficiency, the result is screw pump than the two pump efficiency were 13% higher, 50%.
