Key words:mathematic modeling, thermal conductivity, acid, function distribution.

The study deals with the problem of thermal exposure on the oil reservoir using acidizing of near-wellbore zone. There is a comparison of the oil recovery factor in cases of conventional water flooding, water flooding with the injection of coolant, water flooding with acid exposure and mixed technology. The obtained results show that the joint exposure of heat and acid treatment is the most effective mode of the oil recovery.
