黔北页岩对CH_4、N_2、CO_2的吸附分析

Adsorption Analysis of CH_4, N_2 and CO_2 in Northern Guizhou Shale

页岩气主要成分为CH_4和N_2,驱替CH_4的首选气体为CO_2。为了获取黔北页岩对CH_4、N_2和CO_2的吸附特性数据,选取凤参1井样品在不同温度与压力下进行吸附实验,并进行吸附力计算。研究黔北页岩对CH_4、N_2和CO_2的吸附特性对页岩气资源评价与开发具有指导意义。

The main components of shale gas are CH4 and N2,the preferred gas is CO2 for the displacementof CH4. In order to obtain data on the adsorption characteristics of shale in northern Guizhou to CH4,N2and CO2,a sample of Fengcan 1 was selected for adsorption at different temperatures and pressures,theadsorption force also is calculated. The research has a guiding significance of evaluation and developmentof shale gas resources that is the adsorption characteristics of shale in northern Guizhou to CH4,N2 and CO2.
