考虑多组分吸附的页岩气储量计算方法
Calculation Method of Shale Gas Reserves by Considering Multi-component Adsorption
摘要
Abstract
Aiming at the characteristics and existing state of shale gas reservoir,based on the principle of adsorption gas desorption,using material balance theory,Bangham deformation theory and extended Langmuir adsorption model,the material balance equation of the multi-component adsorption of shale gas reservoir is derived.Linearizing the material balance equation,the dynamic reserve calculation method based on the material balance equation is obtained.The calculation results show that the multi-component and the adsorbed phase volume have a great influence on shale gas in-place calculation.Considering their influence,the calculation model is more practical and the results are more accurate.关键词
