摘要
渤海东部海域发现一个亿吨级花岗岩潜山油藏，根据岩心、岩石薄片、铸体薄片、常规测井、成像测井及分析化验等资料，研究了潜山储集空间类型和物性特征，在纵向上将潜山分为强烈风化溶蚀、次级风化裂缝和微裂缝3个储层发育带，不同发育带的储集空间类型存在差异。利用地震多属性技术综合分析和预测了潜山储层发育展布特征，指导该地区下一步油气勘探，同时也为地质条件相似的其他潜山区块提供借鉴。
Recently, the granite buried hill oil pool was discovered in East Bohai Bay, which reserves are over one hundred million tons. According to the comprehensive studies of the cores, rock slices, casted thin-sections, conventional well logging, imaging logging and testing-analyzing data, the accumulative space （AS } types and the characteristics of physical properties are analyzed ; the buried hill is vertically classified into three belts of well-de- veloped reservoirs： intensively-weathered shattered reservoirs, lightly weathered fractured reservoirs and microfrac- tured belts. There are a certain differences in the space types with various developed belts. With the help of the comprehensive analyses of seismic multi-attributes technique, the developed and expended characteristics of the reservoirs are predicted, thus the further petroleum exploration for the region is guided. At the same time, the a- chievements above have also provided the other buried hill blocks with the similar geological conditions.
