摘要
本文解剖了酒西盆地烃源岩发育的地质背景及主要烃源岩的性质、分布规律,分析了油气生成期与圈闭发育期的配置关系、油气运移方向与通道、储集岩特征及分布、区域盖层分布与成藏规律,总结了该盆地油气生、储、盖、运、圈、保的基本规律。在此基础上,研究了制约酒西盆地的主要油气成藏条件,并指出了有利的勘探领域及目标。
Abstract
In this paper,the geologic background of source rock development and the properties and distributive rules of source rocks in the Jiuxi Basin are dissected,the disposition relation of petroleum generating period to trap-developing period,the direction and pathway of petroleum migration,the characteristics and distribution of reservoir rocks,regional cover rock distribution and pool-forming rules are analyzed,and the basic regularity for the generation,storage,capping,migration,trapping and preservation of petroleum in the basin are summarized.On this base,the main petroleum pool-forming condtions which restrict the Jiuxi Basin are studied,and the favorable exploration domains and targets are pointed out.
