In this paper the method teplopolimernogo impact on viscous oil deposits, determined the effectiveness of this method. This topic is relevant because Russia has about 50 % of residual oil up as reserves from oil increased and high viscosity. The effectiveness of the method teplopolimernogo exposure is a significant increase to 40-45 % recovery and reducing costs in the development of deposits of viscous oil. State of the hydrocarbon resource base in Russia and in the world as a whole is characterized by a significant increase in the share of hard-permeability reservoirs with oil increased and high viscosity. in almost all fields of Russia, regardless of their geological characteristics features continue to be developed with the use of traditional technologies with flooding or natural mode. It is quite obvious that the application of flooding can not be justified in almost all fields with carbonate, fractured porous reservoirs with abnormal oil. If flooding technology traditionally used in carbonate reservoirs with oil increased and high viscosity can provide the ultimate oil recovery is not more than 20-25 %, the new technologies allow increasing the oil recoveryupto 40-45 %. Which have no analogues in the world practice thermopolymer technology stimulation scientifically justified as inventions and patents, tested and widely implemented in production.
