摘　　要：砾岩油藏的非均质性特征决定了砾岩油藏总体开发效果较差,尤其是油藏进入中高含水期后常常出现"两快"、"两低"现象,即含水上升快,产量递减快,注水利用率低,剖面动用程度低。剩余油分布认识不清,剩余储量难以调动,油藏开发后期挖潜调整难度较大。根据砾岩油藏中高含水期特点,对克拉玛依油田八区克上组油藏进行了油藏数值模拟研究,量化了剩余油分布,并对影响开发效果的关键因素进行了指标预测和优选,提出油藏合理开发方式及开采技术界限。根据数值模拟跟踪研究成果实施二次开发调整,新井初期产能及剩余油与数模剩余油研究及预测结果符合率达90%,表明油藏数值模拟技术在砾岩油藏中高含水期控制含水上升、提高采收率、制定高效科学合理开发政策等方面具有重要的应用价值。The conglomerate reservoir with heterogeneity characteristics results in the overall poor development of conglomerate reservoir,Especially the reservoir into the high water perlod is often with a 'two-speed' and 'two-low' phenomenon: water rises rapidly;production declines rapidly;utilization ratio of water is low;low profile is used.It is uncertaion of the distribution of remaining oil,so remaining reserves are difficult to be activated,and reservoir development is difficult to be adjusted later.Based on conglomerate reservoir characteristics of high water cut,the Higher Karamay reservoir in District 8 is studied with reservoir simulation,and the remaining oil distribution is quantified.The key factors affecting the development were predcted and optimized so as to propose reservoir development methods and reasonable limits of technology Based on the simulation results of tracking the implementation of secondary development of adjustment,the results of initial production capacity of new wells and the remaining oil are 90% match with prediction,which shows its significance in oil development.
