FIELD: interpretation of geophysical surveys of wells.
SUBSTANCE: invention is intended for determination of conditional permeability of reservoirs in conditions of layered anisotropic reservoir. To determine conditional permeability, approximations Reuss (at inclination of the well axis of 180 degrees to the bedding plane) and Voigt are used, as well as averaging along the Hill (at inclination of the well axis of 90 degrees to the bedding plane). Input data for implementation of proposed method are results of determination of porosity and permeability on core samples, continuous curve of porosity, as well as results of section clustering by well logging data.
EFFECT: improving accuracy and reliability of reservoir permeability coefficient determination in conditions of complex layered deposits.
