页岩气吸附综合模型及其应用

页岩气藏中吸附气体占很大比例,吸附气的含量直接关系到页岩的储量计算,因此准确得到页岩的吸附气含量至关重要。通过不同温度下页岩等温吸附实验发现温度升高页岩的吸附能力下降;对不同温度下页岩等温吸附曲线进行一系列计算得到了页岩气吸附综合模型,该模型可以用来计算不同温度和压力条件下等温吸附曲线,该模型为页岩吸附气含量的准确计算提供一种方法和依据。

A comprehensive model for adsorption of methane on gas shale and its application

Adsorption gas directly related to the calculation of reserves accounts for a large proportion of gas content in shale gas reservoir. So it is crucial to accurately calculate the adsorbed gas content. Based on experiment at different temperatures it is found that the adsorption capacity of the shale decreased with the temperature increases; A comprehensive model for the adsorption of methane on gas shale is obtained through series calculations of shale adsorption isotherm curves under different temperatures; the model can be used to calculate the isothermal adsorption curves of the gas under different temperatures and pressures;the comprehensive adsorption model provides a method for the accurate calculation of the content of the adsorbed gas.
