【摘要】 针对胜利油田的大多数区块已处于开发中后期的现状,寻求通过对老区进行精细的开发地质研究以达到增储上产的目的研究方法,本次研究通过对永66块的详细解剖,提出了地层等时精细化—构造微型化—储层针对化的开发地质研究方法。首先以小层划分为基础对地层进行细分,对沉积时间单元进行分析,充分对研究区内的地层进行研究;通过开发三维地震的解释,对砂层组顶面构造进行分析,再利用开发井分层数据,对小层顶面微构造进行研究;通过针对沉积微相、隔夹层以及储层非均质性的分析对储层进行研究,并在永66断块取得了良好效果。更多还原

【Abstract】 In this paper,because most of the reservoirs in Shengli oilfield developed in mid-later stage,we want to find a kind of method to increase the reserves and add the produce,by fine researching development geology.And in this research,through the research of the Yong 66 fault-block,we submitted the method of fine stratigraphic classification,microminiaturize structure and oriented research of reservoirs.First,the strata was subdivided on the base of the subzone classification,and analyzed the sedimentary time unit,researched the strata in work area.By the three-dimensional interpretation,we analyzed the structure of the Member superface,and used the individual layer data of development well,researched the microtectonics of the subzone.Last,we researched the reservoir characteristic by analyzing the sedimentary microfacies,barrier bed,and reservoir heterogeneity.And favorable effectiveness was obtained.更多还原
