| Abstract: |
| Unconventional oil and gas resources are abundant and have broad development prospects.Reservoirs in China with low-permeability/ultra-low-permeability are mainly continental deposit.Reservoir characteristics are quite different,with many narrow pore-throats and low porosity.A large amount of recoverable crude oil and gas is residual in sub-micron pores,which is technically difficult to extract,leading to a rather low recovery efficiency.The key scientific problems in this realm include the microscopic mechanical interactions of rock/oil interface and the underlying mechanism of confined molecular transport.In recent years,molecular simulation has become an important research tool in the field of unconventional oil and gas exploitation.This short review starts with an introduction to the principle of molecular simulations,then shows the molecular models of components of unconventional oil and gas reservoirs,and discusses the applications of molecular simulation in unconventional oil and gas development and the related research progress. |
