大情字井油田下泵深度及抽油机机型优选

大情字井油田自2000年进行滚动开发以来,对合理下泵深度的确定,一直处于摸索试验过程中,至今没有合理统一的认识。开发过程中存在两种不同的意见,油藏研究认为应该加深泵挂,以最大程度地满足提液要求;采油工程部门认为下泵深度必须合理,以获得最大的提升免修期和系统效率。文章对大情字井油田下泵深度的优选提出了新的研究思路,并经过对油田前期大量生产数据的统计利用,系统地进行数据回归分析,从而优选出合理的泵挂。在优选出合理泵挂的基础上对节能抽油机的选型提出了新的认识,进一步推动了大情字井油田节能抽油机的合理配备,使抽油机载荷利用率长期处于合理水平(60%~85%)。

Optimization of Pump Setting Depth and Pumping Unit in Daqingzijing Oilfield

This paper will present a new research way of the pump setting depth in Daqingzijing oilfield, and utilizing a lot of producing data analyze the disciplinarian between the flow press and daily fluid production rate ,so fix the optimum pump setting depth. Based on selecting the optimum pump setting depth, this paper present a new cognition to chose pumping unit, and promote the rational matching of pumping unit in Daqingzijng oilfield, finally make the load utilization rate on the optimum level(60%-85%)in long-time.
