油田进入特高含水期开发阶段,油层大部分已水淹,剩余油分布零散,油井措施选井、选层难度加大,效果变差。利用精细地质研究及多学科研究成果,对剩余油沉积分布进行了细致分析,并结合动静态监测资料,根据开发产状,分析评价近年来油井各类措施效果,提出油井压裂优化的方案。对压裂进行了分析,论述了油井压裂的时机,选井选层及工艺优选方法。 When the oilfield enters the development stage of the ultra-high water-cut stage, most of the oil layers have been flooded and the remaining oil is scattered. Selecting oil wells for well selection and layer selection increases the difficulty and the effect becomes worse. Based on the analysis of dynamic and static monitoring data and the analysis of the effects of various measures of oil wells in recent years, a scheme of oil well fracturing optimization is put forward based on the detailed geological research and multidisciplinary research results. The fracturing is analyzed, and the timing of well fracturing, the selection of well layers and the process optimization method are discussed.
