The problem of fluid filtration into a producing well in a reservoir with the properties depending on the stress-strain state is studied. The primary attention is devoted to anisotropy of the strength properties of reservoir rocks and to the influence of fluid pressure on the redistribution of stresses in formation. The problem is solved for two variants of the bottomhole design: an open hole and a hole with two diametrically opposed vertical cuts. The first variant, corresponding to a relatively simple geometry, allows to obtain solution qualified for comparison with analytical one.
