摘要： 准噶尔盆地南缘下组合发育3套主要储集层，即上侏罗统喀拉扎组、齐古组和下白垩统清水河组。储集层岩石类型主要为长石岩屑砂岩和岩屑长石砂岩，总体上表现为较低成分成熟度、中等-较好结构成熟度。成岩作用较弱，处在早成岩的A期和B期。孔隙类型以剩余原生粒间孔为主，少量溶蚀孔，储集层物性较好。3套储集层的累计厚度普遍大于100 m，部分地区250~300 m，大部分地区具有2套和3套的叠合，具有区域性分布的特点。

Abstract: In the lower combination in southern margin of Jungar basin mainly developed three sets of major reservoirs: the Kalaza formation and the Qigu formation of Upper Jurassic and the Qingshuihe formation of Lower Cretaceous, with the main rock types of feldspar lithic sandstone and lithic arkose, and the overall properties of low compositional maturity and medium-high textural maturity as well as weak diagenesis (in the early diagenetic stage of A and B). The pore types are dominated by residual original intergranular pores and fewer dissolved pores. The whole reservoir is characterized by the deep-burial and high quality. The cumulative thickness of the three sets of reservoirs with the characteristics of regional distribution generally exceeds 100 m, some area up to 250~300 m, and most of the area has two and three sets of overlapping
