| 摘 要： | 四川盆地是我国南方最大的含油气盆地,也是我国一个主要的叠合盆地,其海相领域油气地质条件具有3个专属性问题:(①叠合盆地,其特征是盆地基底具三层构造和三分性、沉积盖层纵向演化经历了台地(海相)、盆地(陆相)和褶皱隆升改造三大阶段、现今盆地构造特征可分为4大区11小区;②碳酸岩盐储层,其特征表现为储集岩的孔隙度与渗透率较低、裂缝发育、非均质性较强;③天然气,具来源多样化、运移相态多样化、赋存形式多样化的特征。四川盆地海相领域天然气多由原油裂解而来。影响和控制四川盆地现今油气藏分布最直接的因素及其作用是:烃源控区,储层控层,圈闭控位。四川盆地碳酸盐岩油气藏呈现多样性特征,因此其勘探策略也应多样化。

| Abstract: | The Sichuan Basin is the biggest petroliferous basin in southern China and also one of the most impor- tant superimposed basins in China.Its specific petroleum geologic conditions of marine facies can be expounded in the following three aspects:(1) superimposed basin,(2) carbonate reservoir,and(3) natural gas.The Basin is a superimposed basin.Its basement can be divided into three parts.The sedimentary cover had undergone three evolutionary stages,including platform (marine facies) ,basin (continential faci... |
