Annotation:
The article discusses the thermal effect on an oil formation using downhole steam and gas generating devices, planned for installation in a well with a dual system of wellbores. The results of a laboratory experiment to determine the rheological properties of high-viscous oil, which determine the optimal temperature of a formation heating, are presented. The results of calculating the radius of the formation heating up to the target temperature, which allows optimization of oil production, are discussed. A variant of thermo-physical calculation using the data of the laboratory experiment is proposed, which facilitates the choice of technology parameters and the position of the production well bottom hole in relation to the heating source during design.
