| 摘 要： | 吐哈盆地台北富油凹陷胜北构造带的原油为水西沟煤系源岩及七克台组湖相源岩所生,天然气为煤型气。油源对比结果表明:七克台组以上含油气层的原油主要为湖相油,天然气主要为煤型气;七克台组以下含油气层的原油主要为煤型油,主要成藏期为晚第三纪末。胜北构造带成藏要素的配置关系,控制了本区不同类型油气的分布规律。晚第三纪七克台组湖相原油通过断裂运移时,优先聚集在物性较好的白垩系储层中;晚第三纪末—第四纪,在煤型气向上运移过程中,可以进入稠油堵塞、储集层物性较差的侏罗系喀拉扎组砂岩,形成凝析气藏。由于喀拉扎组中上部厚层泥岩封堵性好,天然气只有一部分继续向上运移到白垩系连木沁组油藏,形成了现今胜北构造带纵向上上油下气的分布特点。

| Abstract: | The oil in Shengbei structure belt of rich hydrocarbon Taibei sag in Tuha basin is sourced from Shuixigou Group and Qiketai Formation lacustrine facies rock resources,and the gas is coal-related gas.Above the hydrocarbon bearing interval of Qiketai Formation,the oil is mainly lacustrine facies oil and the gas is mainly coal-related gas.Below the hydrocarbon bearing interval of Qiketai Formation,the oil is mainly coal-related oil and the main accumulation stage is on Late Tertiary.Allocation relationship on ... |
