Method includes installation of a production pump with pipes routing and well reservoir treatment, with heated fluid and depression. Heat the fluid in a dib hole, with it supply from a wellhead via tubes into the dib hole. Create depression by pumping fluid calculated part via jet pumps, installed over the reservoir, pumping the fluid form a bottom hole for depression creation. Execute calculation of the fluid volume, which pumped via jet pumps, according to condition to provide pumping capacity, which is equal of greater to volume of fluid leaving the bottom hole. When necessary to increase well's oil recovery rate, create in it two horizontal areas: in the reservoir and in the dib hole. Use dib well soil heat to heat up the fluid.
