Through the above analysis, the problems and defects of the prior art are as follows:

1. the shrinkage volume of the heating underground petroleum casing pipe is shortened and the heating underground petroleum casing pipe is cracked due to the fact that the heating underground petroleum casing pipe is cooled in winter.

2. In summer, the heat is accumulated, so that the underground petroleum casing pipe cannot be dissipated when being heated, the volume of the underground petroleum casing pipe expands outwards, and the underground petroleum casing pipe is cracked.

In the prior art, the length of the heated oil casing pipe is increased and the length of the heated oil casing pipe is shortened after the heated oil casing pipe is cooled, the local part of the oil casing pipe can be pulled or burst, the water diversion and heat exchange are blocked, and the effect is poor.

The difficulty in solving the above problems and defects is:

1. the internal stress calculation data is complex;

2. the material has good ductility and toughness and high corrosion resistance at high temperature and low temperature.

The significance of solving the problems and the defects is as follows:

1. the ductility of thermal expansion can be effectively solved, and the expansion is free and flexible like a spring;

2. the problem of normal supply of a heat source during heating can be effectively solved, and the stability, reliability and economy are greatly improved.
