CABLE SUPPORT SYSTEM AND METHOD

摘要

A method is described for supporting a bundle of cables in a well or in a length of coiled tubing deployed in a vertical or deviated well during a process for assembly of a well heater which includes steps of injecting the cables from respective spools into the coiled tubing. The method includes the steps of: attaching an open-ended cable support adapter to the up-hole end of the coiled tubing, attaching a cable bundle clamp to the bundle of cables above the cable support adapter; cutting the cables from their respective spools above the cable bundle clamp; clamping a wedging tube carrier to the cable bundle above the cable bundle clamp; raising the cable bundle; removing the cable bundle clamp from the cable bundle; lowering the cables to insert the wedging tube into the adapter; and removing the wedging tube carrier from the bundle of cables.

1. A method for supporting a bundle of cables in a well or in a length of coiled tubing deployed in a vertical or deviated well during a process for assembly of a well heater which includes steps of injecting the cables from respective spools into the coiled tubing, the method comprising:
a) attaching an open-ended cable support adapter to the up-hole end of the coiled tubing, the adapter having an upper flat surface extending laterally outward from the outer diameter of the coiled tubing; b) attaching a cable bundle clamp having a lower flat surface to the bundle of cables above the cable support adapter; c) injecting the cables further downward into the coiled tubing so that the lower flat surface of the cable bundle clamp rests upon the upper flat surface of the cable support adapter; d) cutting the cables from their respective spools above the cable bundle clamp, thereby transferring the support of the weight of the deployed cables from the spools to the cable bundle clamp and the adapter; e) clamping a wedging tube carrier to the cable bundle above the cable bundle clamp, the wedging tube carrier having a wedging tube reversibly attached to its lower end, the wedging tube having an inner surface shaped to conform to the shape of one or more of the cables and an outer surface configured for weight bearing frictional contact with the inner sidewall of the cable support adapter; f) connecting a lifter to the wedging tube carrier and raising the cable bundle using the lifter; g) removing the cable bundle clamp from the cable bundle; h) lowering the cables using the lifter to insert the wedging tube into the adapter to bring them into substantive weight bearing frictional contact with the inner sidewall of the adapter; and i) removing the wedging tube carrier from the bundle of cables.
