摘要
研究了井口回压对抽油井泵效的影响。计算泵效时考虑了抽油杆-油管的弹性伸缩、抽油泵漏失、抽油泵充满程度等因素，利用编制的抽油井泵效与井口回压关系计算程序，对葡北的11口油井进行了计算。结果表明：葡北地区泵效与井口回压基本成线性关系，井口回压每增加1Mpa，泵效降低1％～2％。
The effect of wellhead back pressure on POWP pump efficiency is studied. The elastica collapsing of pump rod-oil tube, pump leaking, pump fluid level were examined on calculating the pump efficiency. By using the calculator program of pump efficiency and wellhead back pressure, the 11 wells of PU-BEI can be calculated. It was found that the pump efficiency and wellhead back pressure could reach linear relationship, the pump efficiency declines 1% -2% by wellhead back pressure increases 1MPa.
