Underground Thermal Compensator

In the process of heavy oil exploitation, using steam injection reduces oil viscosity, increase fluidity, and our company development the K331 - 152 Type Thermal Metal isolation packer is used isolate the Loop space of the tubing and casing , to maintain a low temperature and pressure, thereby protecting casing, to prevent heat diffusion, remove any circular space back, into the reservoir to protect the heat effectively to reduce crude oil viscosity, is essential for heavy oil recovery in the downhole tool.
