FILTRATION OF A GAS-CONDENSATE MIXTURE NEAR THE HYDRAULIC FRACTURE
O. Yu. Dinariev and N. V. Evseev UDC 532.546 The problem of filtration of a gas-condensate mixture near the operating well with a hydraulic fracture has been investigated. It was assumed that flow is three-dimensional in the matrix and two-dimensional on the fracture. It has been shown that for steady-state flow, the problem is split into a purely physicochemical problem on phase transitions and a nonlinear partial boundary-value problem for the pressure field. An example of numerical solution for the fracture with a prescribed conductivity field has been given. O. Yu. Schmidt Institute of the Physics of the Earth, Russian Academy of Sciences, 10, Ul. B.
