| 摘 要： | 东濮凹陷深层(3500m以下)天然气资源丰富。按气藏产状将深层气藏分为构造型、非构造型和复合型气藏。受生气洼陷、区域盖层、深层高压和煤系二次生烃的控制，深层气富集于较大的继承性隆起和岩性砂体发育区。次生孔隙发育带是深层气藏高产的关键。环洼带是寻找下第三系油成气藏的有利区域，中央隆起带为煤成气有利勘探方向。

| Abstract: | Natural gas is abundant in deep layer (under 3500m) of Dongpu Depression. According to its occurrence, the deep gas reservoir would be divided into structural , non-stuctural and composite reservoirs. Under control of gas generating sub-depression; regional cap-rock, deep high pressure, secondary hydrocarbon generation of coal-bearing series, deep-seated gas is concentrated in inherited uplifts and lithologic sandbody growing area. Secondary pore growing zone is the key of high production of deep-seated gas reservoir, ring sub-depression zone is beneficial area for finding lower Tertiary oil formed gas reservoir, central uplift zone is beneficial exploration direction of coal-formed gas . |
