摘要
为了弄清煤层气贮层中地下水溶解煤层气的特征与规律,利用试验方法,在实验室条件下分别研究了温度和压力对水溶解煤层气特征的影响,并以采集到的阜新矿务局王营矿地下水和煤层气样品为例,研究了煤层气在水中溶解度的变化规律,得出了水对甲烷的溶解度与温度成负相关关系﹑与压力成正相关关系的结论,总结了王营矿水溶气的特点。测试结果表明,王营矿区煤层气在水中的溶解度与一般的水溶气的规律是一致的。
This study aims to investigate experimentally the characteristics and regulation of water dissolving coal gas .Based on the test in the lab, the paper studies the influence of temperature and pressure on the characteristics of water dissolving coal gas. With the sample of ground water and coal gas in Fuxin Mining Bureau, the variation regulation of the coal gas solubility in water is found, and the conclusion is then drawn that the methane solubility in water is positive proportional to temperature and negative proportional to pressure. The test results show that the coal gas solubility in water in Wangying mine area is in agreement with the general regulation of gas solubility in water.
