PRESSURE FIELD IN THE PROCESS OF RADIAL FILTRATION IN A NONUNIFORM ORTHOTROPIC STRATUM IN THE ASYMPTOTIC APPROXIMATION

Simple analytical formulas for defi nition of the pressure fi eld, formed in the process of continuous withdrawal of a fluid from a nonuniform anisotropic stratum, in the zero and fi rst approximations on the assumption that the fl uid flow in the stratum is one-dimensional and linear were derived on the basis of the modifi ed asymptotic method exact on average. The results of calculations of the pressure fi elds in such stratums by the formulas obtained are presented.
