Investigation of the Rheology of Fluids in Fracture and Pore Channels and Determination of Their Opening

The authors propose a procedure to determine the parameters of a medium on the basis of generalization of results obtained in steady-state motion of viscous and anomalous fluids in a plane-radial fracture. Also, the authors have developed a procedure to investigate the rheology of fluids and to determine the fracture opening and the equivalent permeability coefficient in a fracture system and have shown from these assessments the possibility of fluid inflow from a fractured-porous medium. It has been substantiated that the parameters of fracture and pore channels and rheophysical parameters of fluids in these channels can only be determined on the basis of experimental investigations.
