| description | The invention relates to an oil recovery method of closed circulation and viscosity breakback of hot oil in a viscous oil well and a device; the method comprises the following steps of: putting the crude oil into a heating system of a special device, adopting two sets of systems with burning of coal or gas or a single system with burning of coal or gas, being capable of adopting one well with one system or a plurality of wells with one system, and heating and injecting the crude oil into the well for closed circulation. The device comprises a heating system, a buffering tank, an injecting circulating system and an oil pumping system; the circulating system comprises a telescoped central pipe and a telescoped outer sleeve; the telescoped central pipe is sleeved into the telescoped outer pipe, an opening of the lower end thereof is a free end and the upper end thereof is connected with a circulating valve, an injecting pipe, a surface flow pipe, a boosting pump, the buffering tank and the outlet of the heating |
