Abstract: The Jia-2 member is the main reservoir and gas-bearing interval of Jialingjiang formation in the Northeastern Sichuan area. Research on the reservoir has guiding significance to exploration and developing of this area, since Huangcaoxia structure is one of the main favorable areas. Based on the analysis of core, thin section and well logging data, second member of Jialingjiang Formation in Huangcaoxia structures of East Sichuan is identified as different types of dolostone reservoirs, which mainly develop in t
