摘要

凝析气藏在开发过程中，随着地层压力下降，边底水侵入，气井表现出不同的见水特征。采用Cl-、含水率资料将气井产水划分为3类：凝析水、束缚水和边底水。通过分析见凝析水、束缚水、边底水气井的含水、水气比、氯根及米采气指数变化特征，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。

Abstract

In the development process of condensate gas reservoir, with the decline of formation pressure and the invasion of formation water, gas wells present different characteristics. Combining data of Cl- and moisture ratio, water type can be divided into three categories: condensate water, bound water and formation water. Through the analysis of moisture ratio, water-gas ratio, Cl- and gas productivity index per meter of condensate water, bound water and formation water, the influences of different water types on gas reservoir development are studied. Combined with the geological characteristics of gas reservoir, the water controlling measures for different types of gas well are put forward.
