油井检泵周期是描述一口油井正常生产周期长短的一项重要指标。检泵周期的长短直接反映了油井的生产状况和经济效益的好坏。滨南三矿稀油位于单家寺油田的东南部,从构造上看,为一复杂断块油藏。随着油藏开发的逐步深入,由于地层压力的变化、地层亏空、开采措施的影响以及地层流体对地层的浸泡、冲刷,导致岩石骨架应力发生变化,从而使深井泵及其它井下工具的工作条件变得恶劣。因此,如何改善该区块油井的工作状况,对油井躺井原因分析,延长油井检泵周期,成为大家共同关注和探讨的问题。
Oil well inspection pump cycle is an important indicator of the normal production cycle of an oil well. Check the length of the pump cycle directly reflects the production status of the well and the economic benefits of good or bad. Binnan III thin oil is located in the southeast of Shanjiashan Oilfield, from a structural point of view, it is a complex faulted block reservoir. With the deepening of reservoir development, the stress of the rock skeleton changes due to the change of formation pressure, the deficit of strata, the influence of mining measures and the soaking and scouring of formation fluids on the formation, so that the working conditions of deep well pumps and other downhole tools Become bad. Therefore, how to improve the working conditions of oil wells in this block, analyze the reason of well laying in oil wells and extend the period of oil well inspection pumps has become a common concern and discussion.
