Description

Technical Field

[0001] The utility model relates to the technical field of thermal well optical cable laying, in particular to a thermal well optical cable rapid laying fixture. Background Art

[0002] Traditional downhole temperature measurement is done through the platinum resistance temperature sensor on the drill bit. At each formation depth, the corresponding temperature value is measured. It is not possible to continuously measure the temperature values ​​of all locations downhole, and the data can only be saved in the memory card. The data can only be obtained after the drill bit is out of the well.

[0003] By laying temperature sensing optical cables on the outer surface of the thermal pipe, the temperature values ​​of all points on the pipeline can be continuously demodulated and read. By observing the temperature data of the entire pipeline, it is possible to intuitively find out whether there is a leak at the connection of the pipeline, providing data support for the operation of the pipeline. However, at this stage, laying optical cables on pipelines is not only time-consuming and labor-intensive, but also very difficult to protect the survival of the optical cables. The optical cables at the connection position of the thermal pipeline can easily scratch the well wall and cause damage, resulting in a low survival rate of the optical cables, which in turn increases the cost of use and reduces work efficiency.
