为了研究黔北牛蹄塘组页岩的高压吸附特征,选取了黔北凤参1井牛蹄塘组黑色页岩为实验样品,进行高压等温吸附实验,并利用Langmuir方程和多次函数对实验数据进行拟合,分析试样对甲烷的吸附量和吸附速率与压力之间的关系。
In order to study the high-pressure adsorption characteristics of Niutizang shale in northern Guizhou, black shale of Niutizang Formation in Fengshen-1 well of Guizhou was selected as experimental sample for high-pressure isothermal adsorption experiment. Langmuir equation and multiple function Data were fitted to analyze the sample adsorption of methane and adsorption rate and the relationship between the pressure.
