摘要
川西须家河组二段资源量丰富,具有较大的勘探开发潜力.文章以川西中江地区须二气藏特征为基础,结合前人的研究成果,总结出须二气藏的富集规律.古构造高部位是气井高产的前提,裂缝是气井获得中、高产的关键,相对优质储层是气井稳产的基础,断裂是气井高产的重要因素,建立了富集模式,早期近源低效充注,中期远、近源多向充注,致密、构造交互调整,晚期断裂调整富集.
Abstract
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.
