辽河西部凹陷兴隆台高潜山内幕油气藏形成条件和成藏特征
摘要
利用地震、钻井地质和测试资料,结合储层显微镜观察和原油地球化学分析,对辽河西部凹陷兴隆台高潜山的内部结构、储层特点和油气性质进行了研究。结果表明,新发现的兴古7井潜山油气藏不同于以往发现的风化壳型潜山油气藏,它是一种潜山内幕构造裂缝型的混合变质花岗岩基岩油气藏。兴隆台潜山油气藏体系存在分布于潜山顶部附近的不整合遮挡和分布于潜山内幕的构造裂缝型油气藏两种类型。两者油气来源相同、运聚成藏时期相近,但输导体系不同。潜山浅表层油气藏的油气主要通过不整合面输导运移;深层内幕油气藏的油气主要通过裂缝和断层构成的复杂输导体系运移,断层起"大动脉"作用,裂缝起"微循环"作用,油藏间连通较好。兴隆台潜山内幕油气藏的发现揭示了渤海湾盆地潜山内幕是一个具有勘探潜力的新领域。
The structure,reservoir features and petroleum characterization for highly buried-hills of Xinglongtai in west sag of Liaohe depression were studied by the data of the seismic,geological well measuring,DST,microscope measuring of reservoir and analysis of petroleum geochemistry.The results show that the newly found oil pools within the highly buried-hills of Xinglongtai in the west sag of Liaohe depression is different from the conventional oil pools near the top of the buried hills,and the reservoir within the highly buried-hills of Xinglongtai is a kind of fissure reservoir of Archaeozoic hybrid of metagranite,which is developed deeply within the inner of the buried-hills.The reservoir system of the highly buried-hills of Xinglongtai can be divided into two fluid dynamic systems,which are similar in the source and in the maturation of petroleum and different in system of migration passage.Petroleum in the shallow reservoir system near the top of the buried-hills migrates through the unconformity surface,while the petroleum in the reservoir of the inner of the buried-hills migrates through the fault-fissure carrying system.The faults play a very important role in the transporting of the petroleum from the Tertiary source rocks in the sag,and the fissures play a role in petroleum storing and a role in connecting the different reservoirs in microscale.The finding of reservoirs in the inner of the buried-hills foreshows a new potential area to explore in the deep horizons of the Bohai bay Basin.
