摘要
吐哈盆地台南石炭系-下二叠统已见到了油气异常显示,揭示盆地下组合具有较好的勘探前景。钻井、地震、地质露头及磁力异常资料显示台南火山岩储层发育,碳酸盐岩储层也广泛分布。盆地石炭系源岩提供良好的油源条件,并且对上覆地层中油气的贡献不容忽视。台南位于南部下组合潜在生烃凹陷,构造发育,是下组合油气运聚的有利区带,也是鲁克沁古油藏后期调整运移的有利方向。综合分析认为台南地区可能形成构造-火山岩-碳酸盐岩复合型油气藏。
Unconventional activity of oil and gas occurs in the Tainan area of Tuha basin and surrounding Carboniferous-Lower Permian,which indicated a preferable prospecting in lower combination.The data of drilling,seismic information,geological outcrops and magnetic anomaly show that igneous reservoir is developed in Tainan area.Carbonate reservoir is also widely distributed.The source rocks of Carboniferous has a good source conditions in Tuha Basin,whose contribution to oil and gas in the overlying strata can not be ignored.Tainan area is located on the southern region of the lower combination hydrocarbon potential depression and the favorable zone of the migration and accumulation of the lower combination,as well as for the late adjustment migration of Lukeqing paleo-reservoir.It is concluded that it is likely to form the complex hydrocarbon reservoir of structure-igneous rock-carbonate rock style in Tainan area through comprehensively researching.
