通过对野外露头剖面、岩心和镜下薄片分析,探讨了普光气田飞仙关组成岩作用对滩相储层的影响。根据飞仙关组各种成岩环境中不同成岩作用过程与储集空间之间的相互关系,可将普光气田飞仙关组的主要成岩作用划分为：①破坏性成岩作用,如胶结作用等;②建设性成岩作用,如白云石化作用和溶解作用等。区内研究层段中的滩相储层在经过多期胶结作用的改造后,原生孔隙和部分次生孔隙基本消失;混合水白云石化作用和埋藏溶解作用可形成以粒内溶孔、粒间溶孔及晶间溶孔为主的储集空间,对滩相储层中次生孔隙的产生具有重要的影响作用。

Based on field crop,core and thin section analysis,the influence of diagenesis on the beach reservoirs in Feixianguan Formation,PuguangGas Field was synthetically studied.Bymeans of studying the relationship of reservoir space and diageneses in a variety of diagenetic environments,the diageneses can be divided into destructive diagenesis(cementation) and constructive diagenesis(dolomitization and dissolution).The primary pores and part of the secondary pores in beach reservoirs disappeared after cementation.While mixing water dolomitization and burial dissolution which play a significant influence on the development of secondary pores in beach reservoirs,can form reservoir spaces such as intragranular pores,intergranular pores and intercrystal pores.
