| 摘 要： | 根据源-盖控藏理论,结合油源对比结果,对吐哈盆地西部弧形带油气分布规律和油气藏形成的主控因素进行研究.结果表明:西部弧形带油气主要有煤系油、湖相油和二者的混合油3种类型,主力油层原油以煤系油为主,混有少量湖相油,其他含油层位为煤系油;油气远距离运聚成藏主要受4个因素控制,侏罗系水西沟群煤系烃源岩和七克台组湖相烃源岩油气供给充足是油气藏形成的基础;烃源岩大量排烃期由东向西持续隆升的构造脊严格约束油气运移指向和油气藏分布;由不整合面和砂体组成的侧向输导网络是油气远距离运移的关键;白垩系和第三系良好的区域性盖层有效地阻止了油气在长距离运移路径中的散失.

| Abstract: | Based on theory of source and seal controlling hydrocarbon accumulation,associating the newest results of oil and source rock correlation,the distribution of hydrocarbon and dominant control factors of oil and gas field were researched in western arc-like zone of Turpan-hami Basin.The results indicate that there are three kinds of hydrocarbon including hydrocarbon derived from coal,claystone and the mixture.The hydrocarbon of the main layer is derived from coal mixing handful hydrocarbon derived from clayst... |
