摘　　要：普光气田是近年来在川东北发现的大型气田,气田富含硫化氢,其中飞仙关组是气田的主要产气层位之一,主要发育白云岩。飞仙关组储层经历了复杂的成岩作用,主要的成岩事件有压实压溶作用、方解石胶结作用、多期溶蚀作用、重结晶、白云石化作用及破裂作用成岩现象等。根据对孔隙形成、发展的影响分为建设性和破坏性的成岩作用,对储层起建设作用的有溶蚀、白云石化、重结晶以及破裂等作用。这些起建设作用的成岩作用是飞仙关成为一套重要的碳酸盐岩储层。Puguang field is a big one which is rich in hydrogen sulphide in northeastern Sichuan recently. Feixianguan formation is gas producing formation of most important and growth dolomite rock. The Feixianguang reservoir experienced complicated diagenesis such as compaction solution, cementation of calcite, dissolution effect, dolomitization and cataclasm. The diagenesis can be into two type of contribute and destructive according to contribute to porosity formation and evolution. The constructive diagenesis is an important reason for Feixianguan formation.
