摘要

为解决文南油田高油气比井泵效低的问题,引进了二级采油技术。该技术采用特殊的二级采油工具,充分利用油井高油气比的特点,从而达到提高泵效的目的。文南油田30 口井的现场试验表明,该技术应用后,平均单井泵效提高6 %以上,平均单井视动液面下降739 m ,累积增油7 560 t 。

Abstract

In order to solve the problems of slow pump efficiency on high oil-gas ratio well in Wennan Oilfield. We import the secondary oil recovery technique which is made of particular tools to increase the pump efficiency ,and making use of the high oil-gas ratio of well. Having been tested in 30 wells in Wennan Oilfield ,it has shown the average pump efficiency of single well raise 6 % ,the average apparent working fluid level lower 739 m and the accumulative oil production add 7 560 t .
