从储层的微观特征出发,通过铸体薄片、阴极发光等资料分析认为；普光地区飞仙关组储层的岩性以晶粒云岩、颗粒云岩为主；储集空间主要为孔隙(溶孔、溶洞等),裂缝整体不发育.沉积环境控制储层的发育和分布,是普光地区储层形成的重要条件.成岩改造是储层形成的关键,多期次的构造运动导致储层的成岩作用呈多期次、多类型的特征,其结果将地层内的滩相沉积体由原生孔隙为主改造成以次生孔隙占优势的储层,加之储层孔隙较好的保存条件,从而形成了目前储层展布特征.%Start with microscopic characters of reservoir, through various experimental analysis, the following conclusions can be drawn:The rock in Pei xianguan formation of Pu guang area is mainly grain and granule dolomite;The reservoir space is mainly pore(dissolved pore,cave,etc. ) ,The fracture doesn't develop on the whole[1]. The sedimentary environment of the reservoir of this area is innate condition for its formation. The sedimentary environment dominate development and distribution of the reservoir jdiagenetic reconstruction is crucial for reservoir formation,Large-scale tectonic movements lead to a kind of long-term diagesis and change with multiphse and multitype, which transform the previously primary pore dominated shoal facies deposit into secondary pore dominated reservoir, meanwhile, with these preferable preservation conditions,the current distributional features were formed.
