摘要：Shale gas mainly exists in shale pores in adsorbed and free states, and adsorbed state is difficult to be exploited. Therefore, it is of great significance to explore the factors affecting shale adsorption capacity for shale gas exploration and development in China. The current study of molecular dynamics simulation technology in the wettability of shale reservoirs and porosity and permeability of shale adsorption capacity and mechanism research is not deep enough, and need to be further improved. Three main methods of studying shale adsorption capacity and their advantages and disadvantages were introduced. The parameters and characterization methods of shale adsorption capacity studied by predecessors by means of molecular dynamics simulation were analyzed, and the micro mechanism of different influencing factors on shale adsorption capacity were revealed. Among them, temperature, pressure and fluid characteristics are external factors, while pore structure, organic matter type, organic matter maturity and clay mineral type are internal factors. Organic matter type, maturity and clay minerals type can be reflected on the surface of different shale matrix in molecular simulation. This paper mainly expounds the use of molecular simulation technology to study the characterization means and influencing factors of shale adsorption capacity from the molecular scale, and reveals its adsorption mechanism. It overcomes the shortcomings of other research methods, and provides an important theoretical basis for shale dessert optimization and improves the efficiency of future oil and gas exploration in China. ? 2022 Central South University of Technology.
