乌尔逊凹陷“源、断、势”控藏作用及模式
RESERVOIR CONTROLLING ACTIONS AND MODELS OF “SOURCE ROCKS, FAULTS AND POTENTIAL ENERGIES” IN WUERXUN SAG
摘要
Abstract
The oil reservoirs and their spatial distribution relations with their "source rocks, faults and potential energies" are studied for Wuerxun Sag of Hailar Basin, so are done the distributary controlling actions and models of the oil reservoir formation by "the source rocks, faults and potential energies". The controlling action in the formation size by the source rocks is proven; the potential energies control the locations of oil reservoir formation, the low-potential energy area within the inverted fault tilting uplifts controls the oil accumulation and reservoir formation in Nantun and Tongbomiao Formations; and furthermore the low-potential energy area also controls the oil accumulation and reservoir formation in Damoguaihe Formation, the low-potential energy area in the ancient uplift controls the oil accumulation and reservoir formation in base rock; the "faults" dominate oil migration and accumulation,long-term developed faults chock the migration of the generated oil in Nan Member-1 source rocks to Damoguaihe Formation; early expanded faults regulate the oil accumulation in Nantun and Tongbomiao Formations. Proper spatial matching among the above three factor controls the oil reservoir formation and distribution in Wuerxun Sag. However different horizons are characterized by various features; Nantun and Tongbomiao Formations are mainly displayed on the inverted fault tilting uplift; Damoguaihe Formation is principally shown in the inverted structures; the basement rock is focused on the palaeohigh.关键词
