VISCOUS OIL DEVELOPMENT METHOD AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2016 - IPC E21B36/00 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: viscous oil development method includes generation of high pore pressure zone in the formation by supply of preheated water into injecting well and product export from the production casing installed in the developed deposit. At that water is heated up to critical temperature. Device intended for viscous oil development comprises production string, water tank, water pump, water heated connected to the pump output. At that output of the heater is connected to discharge line with the injecting well. At that the discharge line is connected to casing string of the injecting well or to flexible coil tubing and the water heater comprises a nozzle. The production casing is connected by a pipeline to input of the separator having three outputs - the first one for oil, the second one for water and the third one for gas; at that the third separator output is connected to the nozzle.

EFFECT: simplified circuit and design of the device, improved efficiency factor of the process and ensured safety.
