Well pump electrical cable with internal bristle support |
摘要 |
An electrical cable has helically attached bristles for supporting the electrical cable when pulled through a string of coiled tubing to connect to an electrical submersible pump. The electrical cable and helically attached bristles have a circumscribed diameter greater than the inner diameter of the coiled tubing. The bristles deflect in a direction opposite the direction of pulling the electrical cable so that they grip the wall of the coiled tubing. The bristles apply a resistive frictional force to the wall of the coiled tubing, thereby transferring the weight of the electrical cable to the coiled tubing.
