Abstract EN
The complexity of the gas transport mechanism in microfractures and nanopores is caused by the feature of multiscale and multiphysics.
Figuring out the flow mechanism is of great significance for the efficient development of shale gas.
In this paper, an apparent permeability model which covers continue, slip, transition, and molecular flow and geomechanical effect was presented.
Additionally, a mathematical model comprising multiscale, geomechanics, and adsorption phenomenon was proposed to characterize gas flow in the shale reservoir.
The aim of this paper is to investigate some important impacts in the process of gas transportation, which includes the shale stress sensitivity, adsorption phenomenon, and reservoir porosity.
The results reveal that the performance of the multistage fractured horizontal well is strongly influenced by stress sensitivity coefficient.
The cumulative gas production will decrease sharply when the shale gas reservoir stress sensitivity coefficient increases.
In addition, the adsorption phenomenon has an influence on shale gas seepage and sorption capacity; however, the effect of adsorption is very weak in the early gas transport period, and the impact of later will increase.
Moreover, shale porosity also greatly affects the shale gas transportation.
