摘要
本文以沁水盆地的潘庄地区煤层气井产出水的测试数据为依据,利用统计对比方法,以排采时间为主线,对多口井的水质及水型的动态变化规律加以研究分析,得出煤层气井排采112天以后至排采383天之间的产出水水质变化规律:矿化度及各离子浓度大体上呈现下降或者基本稳定的规律,水型在Na-HCO3-Cl型之后并有逐渐向稳定的Na-HCO3型变化的趋势,稳定的产出水的水质水型基本接近该区的地层水水质情况。
Based on the analysis of water produced from the coalbed methane（CBM） wells of Panzhuang district in Qinshui basin,the variation of chemical composition of the water,which was produced from 112 days to 382 days,was studied by the statistical and antithesis method.It is argued that TDS and different ions concentration presented slowly drop or stable,and that the water type changed from Na-HCO3-Cl to Na-HCO3 then kept stable,which was similar to the chemical composition of water in that district.
