构成资阳地区震旦系灯影组储层的岩性主要为具或不具残余颗粒结构的粉-细晶白云岩和白云质岩溶角砾岩,储集空间以次生成因的晶间溶孔、溶洞、角砾间洞和葡萄花边洞为主。现今储层是在长达近六亿年的各种地质作用过程中,经过5个演化阶段后的最终产物,其中沉积相控制着晶粒白云岩储层的展布趋势,所属微相是后期成岩作用的基础;后期埋藏重结晶作用、岩溶作用和构造作用决定着储层内储集空间的具体分布形式。
The lithology of the Dengying Formation of the Sinian Dengying Formation in Ziyang is mainly composed of fine-grained dolomite and dolomitic karst breccia with or without residual grain structure, intergranular dissolved pores with secondary genesis in the reservoir space, , Between the gravel holes and grape lace hole-based. Nowadays, the reservoirs are the final product after five evolution stages in various geological processes of nearly 600 million years. Sedimentary facies controls the distribution trend of the crystalline dolomite reservoirs. The corresponding microfacies are later The basis of diagenesis; post-burial recrystallization, karstification and tectonism determine the specific distribution of reservoir space.
