摘要
哈得逊油田碳酸盐岩缝洞型油藏地质特征复杂,储集体复杂多样。在油田开发前期,由于钻井密度和井间压力等资料缺少,对油藏的认识有一定的制约,需要尽早判定油藏的类型,为制定开发对策做提前准备。通过静态地震资料、测井资料和动态生产特征、能量驱动类型、压力恢复曲线等资料研究,得出研究区主要有定容型油藏和多缝洞连通性油藏两种类型,并分别分析了两种油藏类型的地震反射特征、生产特点。两种类型油藏差异明显,应采用不同的开发策略。
Fractured vuggy carbonate reservoirs in Hadexun oilfield have complex geological features and the reservoirs are complex and diverse.In early stage of oilfield development,because the data of drilling density and pressure between wells is missing,the understanding of reservoirs have certain restriction,to determine the types of reservoir as soon as possible and prepare for the development of countermeasures in advance.By using static seismic data,well logging,dynamic data of the production characteristics,the type of energy drive,the pressure recovery curve,there are mainly two reservoir types,namely the constant volume reservoirs and multi fracture cave and connectivity reservoir.The characteristics and characteristics of these two kinds of oil reservoirs are separately analyzed.There are obvious differences between the two types,and therefore different development strategies should be adopted.
