The problem on the steady fluid filtration to the central well in the deformable formation in regard to the permeability value change in the well bottom zone due to the rock deformation, change of the temperature and fluid viscosity due to the temperature based on heat treatment of the well bottom zone (WBZ) are solved. Simple analytical formulas for determining production rate change dynamics depending on the thermal effect radius of the formation considering the reservoir deformability are obtained.
