| 摘 要： | 东濮地区第三系基底古潜山风化壳储层，发育有奥陶系的碳酸盐风化壳和石炭二迭系及中生界的碎屑岩风化壳。经多次构造运动和风化作用，这些风化壳储层的储集空间类型丰富，形成了各种成因的缝、洞和各种类型的孔隙。其发育和分布受构造运动和性控制。研究表明，东濮地区油源丰富，生油层和储层有良好的接触关系，断层及不整合面构成了良好的运移通道，为古潜山风化壳储层中天然气的聚集及气藏的形成创造了有利条件。

| Abstract: | Weathering crust reservoir was developed in burried hill in DongpuDepression. The stratum for composing the reservoir included ordovician carbonate rock,carboinferous-permian and erosion which made the crust forming various kinds of reservoirspaces,including fracture vugr, and porosity of various origin. The generation anddistribtion of these spaces are controlled by tectonic movement and lithology. The oil resourceof Dongpu Depression are abudant,and source rock are in good contact with reservoir.Faultand unconformity boundary are good ways for gas migration. The gas was accumulated in theweathering crust reservoir and gas pool was formed. |
