Annotation:
The permeability modeling problems are considered with account for the revealed hysteresis effect. It was determined that when the permeability coefficient becomes close to 1 mD with a slight drop of the effective rock pressure, the reservoirs of the Achimov stratum can significantly lose their filtration characteristics. Test calculations performed on synthetic hydrodynamic models showed a decrease in fluid flow rate of more than 10 % only due to taking into account the phenomenon of hysteresis.
