Abstract
The reservoir properties (reservoir properties) of reservoir rocks depend not only on the petrophysical characteristics of the formation, but also on the stresses acting in the rock mass. The redistribution of the latter during drilling causes the occurrence of permeability anisotropy in the near-wellbore zone, which affects not only the flow characteristics of the wells, but also the process of penetration of the drilling mud filtrate into the formation. This should be taken into account when building a geomechanical-electrohydrodynamic model of the near-wellbore space. The results of filtration tests of regularly inhomogeneous cylindrical samples made of artificial geomaterial are presented and a method for synthesizing the dependence of the effective permeability on the polar angle based on the solution of the coefficient inverse problem is proposed. The obtained dependencies added to the database of reservoir properties of rocks used for inversion of GIS data for quantitative assessment of reservoir properties, an example of which is presented in this article.
