【摘要】 针对抽油机井间抽制度难于确定、不便于执行的缺点,从分析油井间开机理入手,阐述了抽油机间抽控制的工作原理．结合低渗透油藏渗流规律,系统研究了抽油机在间抽过程中泵抽产量、沉没度以及液面恢复时沉没度随时间变化特点．通过数学建模、分析与论证,摸索出油井间开规律,为有效执行抽油机井间抽制度、提高泵效、节约电量、延长机杆使用寿命提供了一条新思路．更多还原

【Abstract】 This paper introduces the working principle and application effect of the inter-drilling control of the pumping unit. The method is given to calculate the on-off period according to the ma thematic model and analysis. Engineering practice indicates that the system is up to specifications with stable operation, reliable safety and convenient installation, solves such problems as empty drilling and low efficiency and approaches the purpose of reducing mechanical abrasion, saving electricity and prolonging facility life.更多还原
