It is known that as a result of a nonhomogeneity of petroleum bearing strata, the nature of fluid flow in them varies. In solving the hydrodynamic problem, it becomes necessary to take into account the nonuniformity with respect to permeability from point to point in the stratum. Many papers deal with the determination of the pressure functions in the presence of groups of wells in nonhomogeneous strata. In one reference, this problem is considered for a ribbon-type deposit whose permeability varies according to a power law and which contains N wells. When the change in permeability of the stratum is described by a harmonic function, this problem has been solved (in the cited references), where the value of the permeability on the feed contour does not appear in the formula for the end-face pressure. In this discussion, expressions are derived for the pressure distribution in a circular strata which is nonuniform with respect to permeability, and which contains N wells in one circular group, together with an expression for the movement of liquid particles.
