摘　　要：针对国内有人提出的带能量补偿装置的深井抽油泵（简称“补偿泵”）可以不需要动液面进油的观点，在对常规抽油泵和补偿泵结构及工作原理比较后认为，这两种泵抽油时都要动液面作功，都需要有沉没度。指出采用采油指数概念计算补偿泵的增产量，把机械能量与油层天然能量相提并论是不正确的。采用单相流状态的产量和压力服从直线性ＩＰＲ曲线关系的理论，分析了国内使用补偿泵的油井生产数据的真伪性。对采用抽油泵的抽油井动态分析具有借鉴意义。A comparison between the design feature and working principle of a conventional subside pump and those of a subsurface pump with enemy-compensator shows that,while in operation,both the pumps require the work of working fluid level and a certain submergence.It is pointed out that the mechanical energy and the formation energy cannot be mentioned in the same breath,and it is incorrect to adopt the concept of productivity index for calculating incremental oil production by the compensator.The truthful ness of the production data stemming from some oil wells using subsurface pump with enemy-compensator is analyzed by the IPR curves.
