摘要
通过对柿庄南区块2口煤层气井产出水300 d的连续采样分析,运用统计和对比方法对产出水的地球化学特征进行研究。根据产出水的地球化学动态变化规律,将煤层气井排采过程划分为排污阶段和稳定阶段。
Through collecting water samples of 300 days produced from two CBM wells in south Shizhuang area, used statistics and contrast methods to research the geochemical characteristics of water produced in CBM wells. According to geochemical dynamic evolution of water produced in CBM wells,divided CBM wells drainage process into variation phase and stable phase.
