以露头剖面测量、岩心观察和室内薄片鉴定为依据，探讨了土库曼斯坦萨曼杰佩气田碳酸盐岩储层成岩作用与孔隙演化规律，其中对储层起破坏作用的为胶结、压实一压溶、硅化、硬石膏化及天青石化和次生矿物充填等，而对储层贡献最大的建设性成岩作用主要为白云岩化、重结晶、溶蚀和破裂等，形成了以生物体腔孔、粒间溶孔、粒内溶孔、铸模孔、晶间溶孔和溶裂缝等多种原生与次生孔隙组合的储层基本特征。通过再造成岩序列和恢复孔隙演化历史．可知该气田分别经历了以原生孔隙为主→ 剩余原生孔隙为主→剩余原生孔隙为主叠加次生孔隙→ 次生孔隙为主叠加原生孔隙的组合阶段。

Based on field section measurement，we1l core observation and thin section identification，the diagenesis and porosity evolution of carbonate reservoirs in Samandepe Gas Field，Turkmenistan are synthetically studied．The destructive diageneses are mainly cementation，compaction-pressure solution，silication，anhydritization，sicilianitization and secondary mineral filling,while the constructive diageneses aYe mainly dolomitization，reerystallization，dissolution and fracturing，which results in the basic characteristics of the reservoir that has the combination of a variety of primary secondary porosity types such as organicvisceral pores，intergranular pores，intragranular pores，moldic pores， intercrystal pores，superlarge dissolved pores，dissolved caverns and fractures．On the basis of the reconstruction of diagenetic sequence，the restoration of porosity evolution respectively experienced the following phases：primary pores， residually primary pores，residually primary pores overlapping secondary pores，secondary pores overlapping primary pores·
