Law Of Shale Gas Desorption

The world's energy for the development of a country is becoming increasingly important,while traditional energy prices continue to rise,increasing pollution,in this environment of shale gas as a clean,with great potential resources into view.US shale gas exploration and development success stories led to the development of shale gas resources worldwide.Our shale gas development started late,the current development is only in its infancy,long way to go.Based on the shale gas desorption isothermal experiments,first carried out sample preparation,the physical properties of water balance analysis of experimental samples,and then use this group self-developed set of high temperature and pressure shale gas adsorption and desorption experiment apparatus were storage under conditions of shale gas layer adsorption and desorption experiments,a number of samples obtained isothermal adsorption-desorption curve.And the experimental data were analyzed using different mathematical models were fitted to the data,select fitting variant high accuracy langmuir model as shale gas desorption model.Finally,we study the organic matter content of the sample,mineral composition,temperature,pressure and moisture on shale gas desorption,and the effect of desorption hysteresis on production.
