摘　　要：苏西区是苏里格气田近年来投入开发的重要区块,随着开发规模的不断扩大,部分生产井出现了含水较高的现象。为进一步提高气井综合开发水平,通过水质分析方法对产出水进行部分阴、阳离子质量浓度分析,利用产出水总体化学特征,矿化度与各离子的关系,结合化学特征系数(变质系数、脱硫系数、成因系数)确定了该区的产水类型(正常地层水、淡化地层水、凝析水),并对单井产水类型进行了识别,从而系统地总结了苏西区气田产水规律。最后,简述了产水规律在油气勘探中的应用。The west district in Sulige Gasfield has been a major zone that has been brought into development in recent years. As the proportion is continuously expanded in great extent,the phenomenon of higher water pro-duction exists to some degree in some local producing gas-wells. For raising the comprehensive efficiency of gas exploration further and the method of analysis of water quality was done to the produced water to analyze the con-tent of some Anion and cation, the types of the produced water（normal formation water, desalinized formation wa-ter, condensate water） were definited with the overall chemical characteristics, the relationship between salinity and the content of anion and cation, chemical characteristic data （metamorphic coefficient, desulfurization coeffi-cient, genetic coefficient）, and futher every producing gas-well was distinguished. All in all, the systematic analy-ses were made to the regularities of the produced water in western Sulige Gasfield.Lastly the regularities of the produced water applied to production of oil and gas exploration was showed simply.
