Background

At present, in oil well operation, a power supply cable, a control pipeline and a chemical agent injection pipeline of an electric submersible pump are connected with a working face power supply and a well bottom electric submersible pump through a well head along an oil extraction oil pipe. In order to ensure that the weight of the cable and the pipeline is evenly attached to each section of the oil pipe, prevent the cable and the pipeline from being pulled apart due to the excessive concentration of the weight at a certain point, and simultaneously avoid the damage to the cable and the pipeline caused by the impact, collision and extrusion of the protruding part at the position of a tubing coupling with a casing joint and an inner wall when a pump is put down or lifted or oil is produced, a protection device is needed to fix the cable and the pipeline on the oil pipe.

In addition, because of the requirement of geological design and the like, the oil well can be in a deviated well and a bent well state, when the well inclination angle is larger, the electric submersible pump cable is not centered in the process of lifting and lowering the oil pipe column, and when the oil pipe cable and the pipeline pass through, the cable pipeline can be extruded, rubbed and damaged, and even underground accidents that the cable is blocked, wound and pulled off are caused. The main reason is that when the well inclination angle of a single-connection and duplex cable protector applied on site is large, the cable protector fails to work due to the lateral acting force of an oil pipe string, so that accidents are caused; the power supply cables and pipes are very easily damaged and worn out to cause serious danger during the actual operation.
