APPARATUS WITH COIL SPRINGS AND METHOD FOR SUPPORTING A CABLE IN A TUBING

Helically wound coil springs are wrapped around and attached at regular intervals to a cable, which is positioned within tubing. The support springs are attached to the cable to provide support to the cable. The upper section of each support spring is affixed to the cable. A remainder of each spring...

Beschreibung
Zusammenfassung:	Helically wound coil springs are wrapped around and attached at regular intervals to a cable, which is positioned within tubing. The support springs are attached to the cable to provide support to the cable. The upper section of each support spring is affixed to the cable. A remainder of each spring is formed in a long open helix facing downward when the tubing is installed in a well. The open helix portion of the spring is larger than the inside diameter of the coiled tubing. During placement into the coiled tubing, the springs elongate and decrease in diameter. When the coiled tubing is installed vertically within a well, the springs compress due to the weight of the cable and engage the inside surface of the coiled tubing with a substantial portion of their length, thereby supporting the cable.
