| 摘 要： | 以准噶尔盆地陆东—五彩湾地区石炭系火山岩油气藏为研究对象,利用烃源岩地球化学参数、储层物性和钻井等资料,对其生烃条件、储层特征及演化、油气运移方式和储盖组合进行了系统分析.研究认为：陆东—五彩湾地区主要发育滴水泉组和巴塔玛依内山组共2套烃源岩,有机质成熟度较高;储层物性较好,非均质性较强,不同类型储层物性差别较大;形成英安岩-凝灰岩、火山角砾岩-凝灰岩、玄武岩-泥岩和花岗岩-泥岩等4种储盖组合;油气主要以断裂和不整合面作为运移通道,储集于距石炭系顶面较近的风化壳储层中.

| Abstract: | By use of the geochemical parameters of hydrocarbon source rocks, reservoir properties and drilling data, this paper analyzed the hydrocarbon generation conditions, reservoir characteristics and evolution, hydrocarbon migration pattern and reservoir-eaprock assemblage of Carboniferous volcanic reservoir in Ludong-Wucaiwan area. The result shows that there mainly developed two sets of hydrocarbon source rocks within the Dishuiquan Formation and Batamayi- neishan Formation in Ludong-Wucaiwan area, and the rocks have high organic matter maturity. The reservoirs possess the characteristic of good properties, strong heterogeneity and a greater physical properties difference between different types of reservoir. Faults and unconformity surfaces are the main hydrocarbon migration channel. As the oil and gas enter into the reservoir along these channels, they formed four reservoir-caprock assemblages： dacitetuff, volcanic breccias-tuff, basalt-mudstone and granite-mudstone. Oil and gas reservoirs mainly enrich in the weathering crust reservoir which is close to the top of the Carboniferous. |
