According to the existing problems, the technical personnel develop the superconductive heat transfer wax-removal and prevention sucker rod for wax well wax prevention and thick oil viscosity reduction. For example, in the Chinese patent application 201110254428.5 geothermal superconducting heat transfer wax-removing and-preventing sucker rod, the sucker rod has a double-layer vacuum cavity, two ends of the double-layer vacuum cavity are communicated, after 100 sucker rods are put into a well, a superconducting injection body is filled into the cavity of the sucker rod which is put into the well from the well mouth, and the top end of the sucker rod is sealed after the superconducting liquid is filled. The work is carried out on site, the implementation is difficult, the quality requirement cannot be met necessarily, and the heating effect is poor; another problem with this technique is that the connection of the upper 100 rods needs to be sealed, and if one connection thread is lost, the entire rod string is filled with well fluid and loses its heat transfer function.
Disclosure of Invention
