凝析气藏在开发过程中,随着地层压力下降,气井表现出不同的见水特征。采用Cl-、含水率、矿化度等资料将气井产水划分为凝析水和地层水两类。通过分析气井的含水、矿化度、水气比、氯根等变化特征,研究不同见水类型对气藏开发的影响,并结合气藏的地质特征,提出气井的控水、治水对策。 During the development of condensate gas reservoirs, the gas wells show different water seepage characteristics as the formation pressure drops. Cl-, moisture content, salinity and other data will be divided into condensate water production wells and formation water two types. By analyzing the characteristics of gas wells such as water content, salinity, water vapor ratio and chloride radical, the influence of different water types on the development of gas reservoirs is studied. Combined with the geological characteristics of gas reservoirs, the control measures of water and water are put forward.
