Abstract

Multiphysical model of productive reservoirs includes the description of the main interconnected and interdependent physical processes in the vicinity of the well and the main parameters of these processes. Only by taking into account all essential factors of mud-filtrate invasion, we can build an effective strategy of logging data interpretation, to reliably estimate the reservoir parameters. Otherwise during data inversion unaccounted features of the invaded zone will transfer on the formation properties, and it will result in incorrect forecast of oilfield characteristics. Coupled electrophysical and geomechanical model of borehole environment involves consideration of geomechanical processes during drilling, changes of filtration-volumetric properties of rocks, filtration processes, salt transfer, growth and destruction of the mud cake, change of the electrical characteristics of medium, calculating of electrical and electromagnetic logging data for realistic medium models. To build models authors used software for simulation of filtration processes of two-phase fluid and salt transport under stress-strain state, computer models of the electrical conductivity of heterogeneous medium and programs for calculating readings of electric (BKZ) and electromagnetic (VIKIZ) logging tools for three-dimensional environments, as well as the data of laboratory petrophysical and geomechanical measurements from PetroMechBD database, created with the participation of the authors.
