Annotation:

In the article, based on data on the Botuobinskiy horizon of the Chayandinskiy oil and gas condensate field, the results of modeling the filtration of reservoir fluids and deviations from the field data of geophysical studies of wells (GIS) of the flow rate and specific productivity coefficients of a group of wells, taking into account the heterogeneity of the bottom-hole zone of the formation, are presented. By means of the developed complex mathematical model of mass transfer and multicomponent filtration of reservoir fluids, the specific coefficients of productivity and flow rate of a certain group of wells for homogeneous, layered-heterogeneous and zonal-heterogeneous formations in the bottom-hole zone are calculated.
