METHOD FOR OBTAINING THREE-DIMENSIONAL DISTRIBUTION OF FORMATION PERMEABILITY Russian patent published in 2013 - IPC E21B47/10 G01N15/00 

FIELD: oil and gas industry.

SUBSTANCE: proposed method involves determination based on results of well hydrodynamic investigations, which uncover the formation, which are averaged as per the section of values of current phase permeability, recalculation of current phase permeability to initial permeability as to oil in presence of residual water considering thermobaric conditions in the formation and information on relative phase permeabilities for each investigated well, calculation of non-homogeneous curve of initial permeability as to the section considering the results of geophysical investigations in an open shaft and profiles of influxes of operating phases, correlation of curves and build-up of three-dimensional distribution of permeability.

EFFECT: obtaining profiles as to depth of reliable permeability values, which are suitable to be used in a flow model.
