本文验阐述出:1)盆地沉降中心由西向东迁移中,形成了金湖、溱潼等持续快速沉降型凹陷,其烃源岩厚度大,有机质品质好,热演化程度高;2)处于盆地西部大型河流入湖区的金湖凹陷西部,形成了与阜二段优质烃源岩配套的阜宁组有利储集相带。3)在吴堡运动的残留坳陷区——金湖、溱潼凹陷,烃源岩整体埋藏深度大,热演化程度高,油气资源丰度高.次生油气藏发育。 The paper expounds that: 1) the basin subsidence center migrates from west to east, forming continuous rapid subsidence sags such as Jinhu and Qintong with thick source rocks, high quality of organic matter and high degree of thermal evolution; 2) The western large-scale rivers flow into the lake in the west of Jinhu depression, forming favorable accumulation facies of the Funing Formation which is matched with the high-quality source rocks of Fu-2 Member. 3) In the remaining depression areas of Wubao movement - Jinhu and Qintong sags, the source rocks have large buried depth, high degree of thermal evolution and high oil and gas resource abundance. Secondary oil and gas reservoirs develop.
