AbstractNanoscale pores are widely developed in tight oil, and the scale effect significantly affects the dynamic behavior of crude oil molecules at different positions in the nanopores. The molecular dynamics simulation method was used to study the mechanism of threshold pressure of tight oil molecules at different positions in quartz and calcite nanopores and the influence of pore radius on threshold pressure.
