Hollow rod closed hot water circulation heating in heavy oil well

1. Air source high temperature heat pump for heavy oil well hollow rod closed hot water circulation heating

Working principle: The circulating pump heated by the hollow rod wellbore pumps high-temperature hot water into the insulated coiled tube in the hollow rod, and then enters the annulus between the hollow rod and the insulated coiled tube to heat the hollow rod and transfer the heat to the wellbore for liquid production. The heated low-temperature hot water flows back to the buffer tank through valves and instruments such as filters and flow meters to complete a wellbore heating cycle.

Applications:

2. Circulating heating device pumps the hollow rod closed hot water circulation heating of heavy oil wells

Working principle:  A hollow rod with an outer diameter of Φ42mm is inserted into the tubing, and a continuous insulation pipe is inserted into the hollow rod. The two form an annular space. The circulating pump is used to drive hot water into the continuous insulation pipe. The hollow rod and the continuous insulation pipe The annular space circulates back to the circulation heating device to achieve the purpose of heating the produced liquid.

Applications:
