从南翼山E32 凝析气藏地质特征、措施作业及试采特征分析入手 ,提出了南翼山E32 凝析气藏气水关系模型 ,分析了气藏水淹原因 ,总结了该凝析气藏开发的一些经验及教训 ,指出人工巨型水力压裂是该凝析气藏水淹的潜在原因 ,不合理配产采气是气井水淹的诱导因素 ,不合理井位部署是缩短气藏无水采气期的主要原因。指出层状气水层间互气藏或气水层邻近的气藏 ,特别是层状裂缝型气藏 ,不宜压裂增产采气 ,同时提出该类气藏开发井位部署应远离人工裂缝 ,明确指出控制采气速度特别是人工裂缝附近井的采气速度有利于该类气藏的高效开发。该气藏后期生产特征表明 ,本文分析方法正确 ,结果可靠 ,对同类型气藏的科学开发具有一定的指导和借鉴意义
Based on the analysis of geologic characteristics, operation and characteristics of trial mining of E32 condensate gas reservoir in Nanyishan, a gas-water relationship model was proposed for E32 gas condensate reservoir in Nanyishan. The reason of water flooding in gas reservoir was analyzed. Some experiences and lessons of reservoir development are pointed out. It is pointed out that artificial giant hydraulic fracturing is the potential cause of flooding of condensate gas reservoir. Irrational gas production is an inducing factor of gas flooding. Unreasonable well location is shortening gas reservoir The main reason for the water gas period. It is pointed out that the gas reservoirs in laminar gas-water reservoirs or gas reservoirs adjacent to gas-water reservoirs, especially stratified fractured gas reservoirs, should not be fractured to increase gas production. Meanwhile, it is proposed that the well positions for such gas reservoirs be deployed away from artificial fractures, It is clearly pointed out that controlling the gas production rate, especially the gas production rate near wells near the artificial fractures, is conducive to the efficient development of such gas reservoirs. The later production characteristics of the gas reservoir show that the method of analysis in this paper is correct and the result is reliable. It has some guidance and reference significance for the scientific development of gas reservoirs of the same type
