摘　　要：白垩系卡普沙良群是塔里木盆地北部重要的油气储集层位之一 ,包括亚格列木组层、舒善河组和巴西盖组储集层 (有称为卡普沙良群中上部储集层 )。从储层岩石学、储层物性、储层孔隙结构及储集性控制因素等方面对储层特征进行了系统分析 ,总结储层的储集特征。研究结果表明 ,该储层为砂岩储集岩 ,储层物性及孔隙结构较好 ,储集性纵横向上分别受沉积韵律与沉积相带展布的控制 ,同时还受压实作用、溶蚀作用和胶结作用等成岩作用的控制 ;并认为亚格列木组储集性较好 ,横向上以跨越阿克库勒沙雅西的储集砂体为最好 。Kapushaliang Group of Cretaceous composed of Yagelemu Formation, Shushanhe Formation and Baxiga Formation is one of the important oil gas reservoir horizons in the Northern Tarim basin.In this papper, the characteristics of the reservoir strata is summarized on the basis of petrological and physical features,the texture of porosity and the controlling features of reservoir strata.It was shown that the reservoir strata consist of sandstone with favourable physical features and hole texture.The reservoir is controlled by sedimentary rhythm in profile,by distribution of sedimentary facies in plane, and by such diagenesis as compaction, solution and cementation. Yagelemu Formation is a favourable reservoir in which the sandstone from Akekule to the west of Shaya is the most favourable reservoir.
