摘要
四川盆地下二叠统中次生白云岩及古岩溶是下二叠统主要的非构造圈闭储层之一。该文通过对白云岩的地球化学特征和古岩溶特征的研究,论述了白云岩和古岩溶的形成与分布规律同峨眉地裂运动的关系,以及大中型裂缝圈闭与峨眉地裂运动的关系。
The secondary dolomite and paleokarst of the Lower Permian Series in Sichuan Basin is one of the important atectonic reserviors in the basin. Based on the study of characteristics of the dolomite geochemistry and paleokarst, this paper expounds the relation between the formation of the dolomite or the paleokarst and Taphrogenesis, the relation between the formation of the middle large scaled fissure trap and Emei Taphrogenesis is also discussed, and new hydrocarbon potential areas are suggested in the paper.
