Abstract
In paper model of filtration of drilling agent into fissured and porous medium with extrusion of interstitial water was developed. To solve this problem original numerical algorithm based on implicit finite-difference scheme is proposed. Inverse problem of searching of fissured and porous medium’s parameters is defined as optimization problem. Two methods of problem solution are implemented – method of golden section and method based on genetic algorithm. Results of inverse problem solving for different groups of vary parameters are presented.

Key Words
inverse problem, extrusion, fissured and porous medium, visco-plastic liquid, model of radial filtration
