Understanding the adsorption and transport behavior of shale gas is highly critical for assessing gas-bearing properties reservoirs enhancing recovery. However, underlying mechanism still an open question due to irregularly rough characteristic within nanochannels reservoirs. In this paper, migration in with three-dimensional random roughness studied by using molecular dynamics simulation theoretical analysis. It found that leads intense adsorption, which contributes large reserve phenomenon engineering practice. contrast, significant obstruction gas's transportation observed walls. The exploitation may be improved generating channels/fractures smoother surfaces, increasing pressure gradient, adopting higher temperature. These results should importance our knowledge storage guiding improvement corresponding technologies energy engineering.
