Numerical simulation study of three-dimensional two-phase black oil model in fractured low permeability reservoirs
Online published: 2009-09-16
Alarge number of experimental and field data showthat starting pressure gradient exists in low permeability reservoirs and fracture is more sensitive than the matrix for stress. Based on dual porosity/dual permeability Darcy seepage flow mathematical model, pressure gradient and stress sensitivity are introduced. A seepage flow model in fractured low permeability reservoir is established, and a full-implicit simultaneous solving and examples calculation are carried out.
