In order to improve the understanding of unique state of occurrence of shale gas and gas production law of shale gas, natural gas shale cores and methane were used to carry out gas flow capacity, gas well production dynamics and full life cycle production simulation experiments by using a self-developed simulation experimental device.The experimental results show that the developed experimental equipment and supporting technology have the characteristics of high pressure, long period and multiple measuring points.It can simulate the flow process of shale gas under shale reservoir conditions and preliminarily revealed the shale gas mass transfer mechanism and exhaustion development law.Such as diffusion is the main mass transfer mechanism, the shale matrix pressure propagation is slow, the main production of free gas in the early stage of production, the adsorption gas supply in the late stage and etc.It provides experimental basis for the development of technical policy for shale gas.
