MODELING AND INVESTIGATION OF NONSTATIONARY PRESSURE AND TEMPERATURE FIELDS IN A DEFORMABLE FORMATION DURING THE FILTRATION OF A GAS–CONDENSATE MIXTURE

A procedure and an algorithm have been proposed that allow modeling the problem of identifi cation of parameters of a deformable formation during the fi ltration of a gas–condensate mixture in a gas regime with account taken of the change in the temperature fi eld. In fi nding the parameters involved in the permeability and porosity functions, the author takes minimization of the functional of the quadratic error of calculated and actual pressures at the wellbore as the optimization criterion
