摘要
阐述和回答了有关能量补偿泵的几个核心问题：1．采油过程中油层能量的基本关系；2．油层对动液面作功问题及增产机理；3．抽油机与补偿泵的能量转换问题；4．补偿泵吸入方式问题。指出补偿泵增产的理论基础是油层要对动液面作功，增产方法是不让油层对动液面作功，利用抽油机一段空行程作动力，使一个举升液体的弹簧往复泵工作。
The key problems concerning a subsurface pump with energy compensating device are expounded: the basic relation of the energy supplied by the oil reservoir in the course of oil pumping; work done by the oil reservoir on the working fluid level and the mechanism of productivity increase; energy conversion of the pumping unit and the subsurface pump;suction mode of the subsurface pump. It is pointed out that the theoretical basis of productivity increase by the subsurface pump with energy compensating device is that the oil reservoir does work on the working fluid level, but this work is not required, instead, the idle stroke of the pumping unit is utilized to make a spring reciprocating pump for fluid lifting work.
