【摘要】 四川盆地西南部震旦系灯影组、二叠系和下三叠统嘉陵江组储层中次生成因的孔隙、溶洞、裂缝较发育,经历了多期白云石和石英充填;根据不同期次充填矿物或脉体中有机包裹体的特征和组合类型,以及同期盐水包裹体的均一温度,将烃类在储层中的油气演化和运移聚集期次划分为:1印支期石油大量形成阶段的油气运移和聚集;2燕山期凝析油-湿气演化阶段的油气运移和聚集;3燕山期—喜山期干气演化阶段的天然气大规模运移和聚集。更多还原

【Abstract】 In southwest Sichuan Basin, pore spaces are completely dominated by pores,holes and fractures with secondary origination in the Sinian Dengying Formation,the Permian and the Lower Triassic Jialingjiang Formation.The pore spaces were filled by dolomite and quartz of multiphases.According to the kinds, association types and homogenization temperatures of the fluid inclusions in the filled minerals of different phases, the migration and accumulation of oil-gas can be divided into three stages:①the formation of a large amount of crude oil of Indo-China movement stage;②the condensate oil-humidity gas of the Yanshan movement stage;③the large-scale migration and accumulation of natural gas of Yanshan-Himalayan movement stage.更多还原
