Study on the Enrichment Law of Xu-2 Gas Reservoir in Zhongjiang Area of Western Sichuan
The second member of Xujiahe formation in western Sichuan is rich in resources and has great potential for exploration and development.Based on the characteristics of Xu-2 gas reservoir in Zhongjiang area of western Sichuan,and combined with previous research results,this paper summarizes the enrichment law of Xu-2 gas reservoir that the high position of ancient structure is the premise of high production of gas wells,fractures are the key to achieving medium and high production of gas wells,relatively high-quality reservoirs are the basis of stable production of gas wells,and fractures are important factors for high production of gas wells.The enrichment model is established that the early near-source low efficiency charging,the middle far and near source multi-direction charging,dense and structural interaction adjustment,and the late fault adjustment enrichment.
