Molecular dynamics simulation of three-phase flow in rough quartz nanopores of underground gas storage
摘要
Abstract
Depleted oil reservoirs can be converted to underground gas storages,and multiple rounds of water and gas injection cause three-phase flow in this process.In this paper,molecular dynamics simulation was used to analyze the flow characteristics in rough quartz nanopores in depleted oil reservoirs from a microscopic perspective and to investigate different flow and adsorption phenomena.It was shown that in three-phase flow,intermolecular interactions significantly affected the adsorption distribution,and the gas molecules led to the desorption of oil molecules on the rough wall,which promoted the flow of oil molecules and improved crude oil recovery.关键词
