摘　　要：以勘探程度较低的海外河潜山为研究对象,分析了区域构造特征,并利用岩心分析、测井、地层倾角等多种资料,综合研究了海外河变质岩潜山的储层特征。系统分析了潜山岩石类型和特征、岩性的测井响应特征、储集空间类型及油水关系等多种因素。取得了海外河潜山存在多种岩性组合、地层呈层状分布、可形成储隔层交互分布、油气沿深大断裂向潜山内幕运移并在裂缝高密集带聚集成藏的认识,揭露了潜山内幕油藏发育情况,对深化海外河潜山勘探具有重要意义。Starting with the study of Haiwaihe buried hill which has low exploration degree, this article analyzes the area tectonic characteristics and reservoir characteristics of metamorphic buried hill reservoir in Haiwaihe Area based on the data such as core analysis, logging and stratigraphic dip. It also systematically analyzes the rock type and characteristics, lithologic logging response characteristics, reservoir space type and oil and water relationships. It concludes that the existence of various lithologic combinations in metamorphic buried hill of Haiwaihe Area and samdwich characteristics of stratum make it possible for alternate distribution of reservoirs and barriers and the oil and gas accumulation in high-dense zone of interior reservoirs migrating along with great fault. These understandings disclose the development of buried hill interior reservoir, which has important significance for deepening the exploration of buried hills in Haiwaihe Area.
