川东龙马溪组页岩解吸滞后现象实验研究
Experimental Study on Desorption Hysteresis of Longmaxi Formation Shale in Eastern Sichuan
摘要
Abstract
The physical property and adsorption-desorption performance of the outcrop samples of Longmaxi Formation shale in eastern Si-chuan were tested in order to understand the desorption hysteresis of shale gas in large pressure range and its influencing factors. The ex-perimental results show that,the adsorption and desorption isotherms of methane to shale do not coincide,and there is desorption hystere-sis. The desorption hysteresis is related to the physical parameters of shale,and the worse the physical property of shale,the more complex the pore structure of the shale,the larger the desorption hysteresis loop. The measured adsorption and desorption data of the shale samples were fitted using three kinds of adsorption models,the fitting results show that,compared with Langmuir equation and Freundlich equation, Langmuir-Freundlich equation can better describe the adsorption-desorption characteristics of the shale gas.关键词
