Abstract

The article addresses viscous and high-viscosity oil production methods that are also relevant to Tazovskoye oil-gas condensate field. Heat-affected zones have been identified to assure the most effective development of the viscous and high-viscosity oil field. Study and patent research results have been used to determine four most effective thermal methods of high-viscosity oil rheological properties con-trol: local heating, cocurrent heating, local stage heating, and local cocurrent heating. Existing thermal systems for the implementation of these thermal methods have been analyzed and electrothermal systems based on induction technology have been chosen. The efficiency of induction technology is due to a high range of the thermal flow formed and implementation of two modes: temperature maintenance and emergency heating. Local heating may be ensured by an induction downhole heater of the face area or an induction electric steam generator for the thermal action not only on the face area, but the entire producing formation. A heating device has been proposed based on results of the patent research of induction heating systems for high-viscosity oil. A versatile magnet-operated component has been proposed as a heating body of the induction heating system.
