摘　　要：嘉陵江组是川南地区天然气的主要产层,二里场构造嘉陵江组富有勘探开发潜力。本文结合前人研究成果,依靠岩芯和测井曲线分析,划分认识了研究区嘉陵江组的层序和高频层序特征,建立了层序地层格架;通过岩性、物性、电性、含油气性综合解剖了嘉陵江组储层,编制了高频层序格架内的储层对比图,探讨了储层发育与层序地层的关系,指出区内嘉陵江组溶蚀孔隙型储层发育受三级层序及高频层序控制。Jialingjiang Group is the main natural gas producing area of Southern Sichuan. Erlichang Construction in Jialingjiang Group is full of exploring potential. This paper combining the previous research results and basing on the analysis of rock core and well log,divided the districts of succession of strata and high frequency succession of strata in Jialingjia Group Research District. The sequence stratigraphic framework has been established. According to the lithology, physical property, electrical property and oil-gas possibility, this paper comprehensively dissected the reservoir stratum of Jialingjiang Group. It made the area chart of reservoir stratum in the high frequency sequence stratigraphic framework, and discussed the relation between reservoir stratum development and sequence stratum.Finally, it concluded that the development of dissolved pore type reservoir stratum in Jialingjiang Group are controlled by three-level sequence and high frequency sequence.
