Nonlinear seepage flow of ultralow permeability reservoirs
Nonlinear seepage flow is chiefly caused by medium deformation and threshold pressure gradient (TPG) in low and ultralow permeability reservoirs. According to laboratory experiment on medium deformation and TPG, a novel stress sensitive coefficient is defined, and the variation rules of the coeffici...
