Vacuum heat insulating tubing is an important wellbore heat insulating facility for heavy oil thermal recovery at present. Its heat insulating performance directly affects the thermal recovery efficiency. The research on the heat insulating system of vacuum heat insulating tubing is of great significance to improve and improve the heat insulating performance and enhance the thermal recovery of heavy oil. This paper summarizes and analyses the current research status of vacuum insulated tubing insulation system. It elaborates the insulation structure, insulation materials, annular air charging and vacuum pumping, insulation coating and so on. It provides reference and reference for the future research of vacuum insulated tubing.
Key words: vacuum insulated tubing / thermal insulation; review
