摘要
对传统认为的泵效是由原油中含溶解气和抽油泵沉没度决定的说法进行分析，指出原油中的溶解气并非是影响泵效的主要原因，而原油在泵腔内的气蚀作用是影响泵效提高的主要因素。推导出了泵效计算的有关公式，说明了如何改变抽吸参数提高泵效的方法。
Based on analysis of the traditional view that pumpefficiency is determined by solution gas in crude andsubmergence depth of oil well pump, this paper pointsout that key influential factors of pump efficiency is notsolution gas in crude oil but cavitation of crude in pumpchamber. Pump efficiency calculation formula are deriredand methods are given to improve pump efficiencythrough changing swabbing parameters.
