Background

At present, in the optical fiber logging outside each casing pipe in the petroleum industry, optical fibers need to be lowered to a downhole target layer along with the casing pipe, and due to the fact that downhole working conditions are complex, related tools are needed to fix an optical cable on the outer wall of the casing pipe, so that the optical cable and the casing pipe are integrally conveyed into a well, and the tools adopted at present mainly comprise body rings. The existing body ring has small friction after contacting with the sleeve, can not effectively fix the optical cable and can cause the body ring to slide up and down on the sleeve. The structure is possibly applicable to a horizontal well with a smaller length, and if the horizontal well is overlong; for example, a horizontal well with a complicated well bore structure is not suitable for horizontal wells with a horizontal length of more than 2000 m. When the casing pipe is in the process of descending downwards in a well, the longer the horizontal section is, the larger the impact force applied to the body ring is, when the friction force between the body ring and the casing pipe is smaller than the impact force, the body ring can slide on the casing pipe, the optical cable is not completely attached to the casing pipe and has extra length, when the body ring slides to the position of a casing pipe coupling, the optical cable can be broken due to the extra length, and finally, the failure of the optical fiber monitoring well body structure is ended.
