摘要
推导出计算抽油泵充满系数的公式。通过对公式的分析讨论，找出影响抽油泵充满系数的主要因素。提出在生产中采用井下油气分．离器和井口套管定压放气阀配套技术；采用环形阀、抽油泵增压补偿器和锥阀式抽油泵可以消除气体影响，提高抽油泵充满系数。
The equation for calculating the fullness coefficient of a subsurface pump is derived.Through the discussion of the equation,the main factors influencing the fullness coefficient are found out. It is indicated that,by using a downhole gas separator cooperated with a gas relief valve on wellhead casing or by applying annular valve,pump pressure compensator and cone valve type pump,the adverse influence of gas can be eleminated and the fullness coefficient of the subsurface pump can be improved.
