Characteristics and Controlling Factors of Second Member of Jialingjiang Formation Reservoir in the Huangcaoxia Structure of East Sichuan
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 the subsection of . The reservoir type is defined as fracture-pore type, and the main reservoir spaces are intergranular denudation pore, intercrystalline pore, intercrystalline denudation pore, tectonic fractures and pressolutional fractures. The reservoir is controlled and influenced by sedimentary facies, diagenesis and tectonic factor. The dolomite flat and Oolite bank microfacies are the best reservoir facies belt. Dolomitization and denudation can help to form many pore spacies, and permeability of the reservoir can be enlarged by tectonic factor. These contribute to form a high quality reservoir.
