To study the shale gas adsorption law under the condition of high temperature and high pressure,adsorption device is designed for the shale gas.The adsorption experiments of rock samples and methane gas from a basin in Sichuan are carried out with this device,in different temperature and under the condition of different pressure.The experimental results show that under the condition of the same pressure,the higher the temperature,shale on methane gas adsorption quantity decreases.When the temperature is high,with the increase of temperature,shale of methane adsorption quantity reduces gradually.When a constant temperature and pressure is less than 5 MPa,with the increase of pressure,shale of methane gas adsorption capacity increases gradually.When pressure is high,shale gas adsorption of methane increases at a slow speed;the effect of shale particle mesh on the absorption of shale is not significant.The adsorption law is fitted with Langmuir equation,and fitting results are good.
