礁灰岩油藏隔夹层控制的剩余油分布规律研究
|
摘要
珠江口盆地流花11-1油田是底水驱动的块状生物礁油藏,已处于油田开发中期,礁灰岩油藏内部的隔夹层是影响开发效果的因素之一,也是剩余油分布的主要控制因素。根据岩心、测井、地震、开发动态等资料,将该油田生物礁储集体中隔夹层划分为4类,分析隔夹层的成因及分布特征,揭示了隔夹层对剩余油分布的控制作用。在综合分析油藏动、静态因素的基础上,主要根据隔夹层的研究成果,指出了剩余油潜力区,并在潜力区部署了侧钻井位,实际生产与研究结果一致,取得了明显效果。图6表1参17
The Liuhua 11-1 Oilfield,Zhujiangkou Basin,is bottom water driving massive reef reservoir in the middle development stage,and the intercalations in the reservoir are the main factors affecting the development efficiency and controlling the remaining oil distribution.The genesis and distribution of the intercalations are analyzed on the basis of core,well log,seismic and production data of Liuhua 11-1 Oilfield.Based on the comprehensive analysis of dynamic and static data and the study of intercalations,the remaining oil distributed areas are identified and new sidetrack wells are deployed in the enrichment regions of remaining oil.
