气体在水中的溶解机理及溶解度方程

提出气体在水中的两种溶解机理——间隙填充和水合作用。推导出气体溶解度方程的一般形式。讨论了Henry常数与温度、压力、气体的水合平衡常数和气体的分子体积的关系。用甲烷溶解度的实验数据验证了上述理论,结果表明,在20～160℃和小于60MPa条件下,甲烷溶解度的理论计算值与实验值基本一致。     

Mechanisms and solubility equations of gas dissolving in water

The two mechanisms of gas dissolving in water, interstice filling and aquation, are proposed. General equations of gas solubility have been deduced from the mechanisms and experimental observations. Dependence of Henry's coefficient on temperature, pressure, aquation equilibrium constant and gas molecular wlume is discussed. The theoretical equations were verified by experimental data, which shows that the theoretical results of the solubility of methane are in good agreement with the experimental data in the range of 20 -160℃ and under a pressure of less than 60 MPa.     

多层次模糊综合判别法在煤层气资源丰度潜力评价中的应用

我国煤层气勘探开发尚处初级阶段,煤层气资源丰度潜力评价体系尚不健全.研究应用多层次模糊数学方法,通过对煤层气成藏条件分析探讨,建立多层次模糊判别模式,并根据国内外煤层气勘探开发经验,给出评价函数及函数拐点值.并将方法应用到选取的靶区盆地,定量计算煤层气资源丰度潜力,估算资源量,为靶区提供煤层气勘探决策依据.
