摘　　要：用离子色谱、GC-MS、ICP等分析手段分析西南某页岩气田采出水水质特性,了解页岩气采出水的基本物化性质。结果表明:对页岩气采出水构成污染的主要指标有COD、SS、氨氮、石油类及氯化物等,且随时间的波动范围大,污染物含量随区域变化呈现一定规律;页岩气采出水中的有机物多为烷烃类有机物,还有少量的环己醇、苯胺及萘,微量的挥发性及半挥发性有机物,如单环芳烃类、苯酚类、多环芳烃类及酞酸酯类有机物。The characteristics of shale gas produced water were analyzed by ion chromatography,GC-MS,ICP and other analysis methods and the basic physico-chemical properties were studied.COD,SS,ammonia nitrogen,petroleum and chloride were the main pollutants,their concentrations varied greatly with time and changed with lo-cation in some rule.The most of organic compounds in the shale gas produced water were alkanes,while cyclohex-anol,aniline,naphthalene,volatile organic compounds and semi-volatile organic compounds such as monocyclic aromatic hydrocarbons,phenols,polycyclic aromatic hydrocarbons and phthalates were in small amount.
