摘要
为了加深对渤海KL油田储层连通性的认识并改善开发效果,针对油田2号砂体与3号砂体动态测试连通而静态测试不连通的矛盾问题,运用油井监测资料分析法、井间动态连通性分析法和数值模拟分析法等方法开展了储层连通性研究。研究结果表明2号砂体和3号砂体的地层压力处于同一水平,注水井A14与采油井A18动态数据变化存在很高的关联度,砂体连通情况下的数值拟合效果更佳,因此2号砂体和3号砂体具有很好的连通关系。据此认识,该砂体部署调整井3口,新增探明石油技术可采储量25×104 m3,年均日增油102 m3,取得了较好的增储上产效果,为渤海类似河流相油田储层连通关系的研究及挖潜提供了借鉴。
In order to improve the development effect of 3-1483 sand in KL oilfield of the Bohai Sea,aiming at the contradiction between dynamic and static knowledge of No.2 sand body and No.3 sand body,reservoir connectivity was studied by means of well monitoring data analysis,dynamic connectivity analysis between wells and numerical simulation analysis.The results show that the formation pressure of No.2 sand body and No.3 sand body is at the same level.There is a high correlation between the dynamic data of injection well A14 and production well A18.The numerical simulation fitting effect is better when the sand body is connected.Therefore,No.2 sand body and No.3 sand body have a good connection.Accordingly,three adjustment wells were deployed,with 25×104 m3 of recoverable reserves.The annual average daily increase of oil is 102 m3/d,which has achieved a good effect of increasing reserves and production.It provides reference and ideas for the study of reservoir connectivity in similar fluvial oilfields in the Bohai Sea.
