摘　　要：塔里木盆地古近系卡拉塔尔组碳酸盐岩是喜马拉雅造山运动过程中残余的海相沉积,也是柯克亚气田深部构造的主要储层和油气产出段。较为强烈的成岩改造是控制储层类型发育的主要因素,溶蚀(岩溶)作用、压溶作用、破裂作用和白云石化作用形成次生孔隙,产生的溶孔、溶洞和裂缝是天然气的主要储集空间和运移通道;胶结作用和压实作用可破坏原生孔隙和部分次生孔隙。The Kataer formation of the Tertiary is the remained marine carbonate facies during the Himalaya orogenic movement, and of the major unit ofoil reservoir. The intensive diagenesis is remarkably considered as the key role controlling the formation of reservoir types. Nevertheless, Karst dissolution, dissolution by compression, breakage and dolomisification are respectively of the primary and some secondary poresities and resulting of the crakes, porosities and sutures, which are significant for the reservoir and transportation of the hydrocarbon matters. Moreover, cementation and compression are negative facts of the primary and part of the secondary porosities decline.
