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，为油气的勘探与开采提供了依据
The secondary dolomite and paleokarst in the Lower Permian in the Sichuan Basin are one of the major non-structural trap reservoirs in the Lower Permian. Based on the study on the geochemistry and paleokarst features of dolomite, the paper discusses the relationship between the formation and distribution of dolomite and paleokarst with the ecliptic movement of Emei and the relationship between the large and medium-sized fracture traps and the Emei earth- , Provided the basis for oil and gas exploration and exploitation
