摘要
侏罗系成藏组合是中亚地区阿姆河盆地最重要的成藏组合。通过对岩相古地理、烃源岩、储层、盖层和油气成藏过程以及模式的分析,认为该成藏组合的成藏主控因素主要包括以下几个方面:①广泛分布、已经大范围进入生气窗的优质侏罗系烃源岩为该成藏组合内油气聚集提供了雄厚的物质基础;②优质的上侏罗统储层为油气资源的聚集提供了良好的空间,尤其是生物礁建造,其储集性能优越;③厚层Gaurdak组蒸发岩盖层充当了该成藏组合的优质盖层,除基底断裂分布带外,油气不能穿越它发生垂向运移作用。该成藏组合内油气散失的原因主要是Gaurdak组蒸发岩盖层尖灭或受基底断层破坏而引起油气侧向运移和垂向运移。结论认为:未来的主要勘探潜力在该盆地深部现今由于地震资料品质问题而未能识别出的生物礁和位于油气运移路径上的深部构造,平面上的有利区为大型基底断裂的不发育带。
