摘　　要：本文对塔中１井储层段进行了岩芯、薄片、阴极发光等观察和分析，划分出了角砾白云岩、残余颗粒白云岩和晶粒白云岩３种岩石类型，识别出了白云石化、硅化、方解石化、重晶石化、萤石化、黄铁矿化、自生粘土矿物化以及溶解、压溶等成岩作用类型；归纳出塔中１井储层段经历了３个成岩阶段、４种成岩环境的改造和叠加，并在物性测定的基础上给出３个岩性段的储集条件．The reservoir rocks in Tazhong 1 well are studied based on analysis of cores,thin sections,cathodoluminescenc etc.The dolostones are divided into three types:conglomera ic dolostones,grain dolostones,andcrystalline dolostones.The recognized diagenesis includes dolomitication,silicification dedolomitization,baritization,pyritication,precipitation of clay minerals. dissolution and pressure solution.The reservoir rocks werereformed during three periods fo diagenesis and in four types of diagenetic environments.
