资阳灯影组二、三段储层的形成与岩石微相和微相组合密切相关。该段主要由１２种岩石微相及５种微相组合叠加而成，其中浅色的微晶白云岩、亮晶砂屑白云岩、微亮晶鲕粒白云岩及部分藻叠层白云岩是最有利于储层形成的岩石微相，它们多分布于各微相组合的中上部。岩石微相及微相组合在垂向上的频繁叠加导致储层在纵向上具有层数多、单层厚度不大的特点；平面上，以资３、７井为中心的区块１和以资４井为中心的区块２是有利于储层形成的岩石微相及微相组合地区。
The formation of the second and third member reservoirs in Ziyang Dengying Formation is closely related to the combination of rock microfacies and microfacies. This section is mainly composed of 12 kinds of rock microfacies and 5 kinds of micro-phase combination of superposition, which light-colored microcrystalline dolomite, bright crystalline sand dolomite, micro-spoduolite oolitic dolomite and part of the algae laminated dolomite is Most conducive to the formation of reservoir rock microfacies, which are distributed in the middle of each micro-phase combination. The frequent superimposition of rock microfacies and microfacies in the vertical direction leads to the fact that the reservoirs have many layers in the vertical direction and the thickness of single layer is not large. On the plane, Block 4 centered on well 4 is a combination of microfacies and microfacies that are favorable to reservoir formation.
