Abstract
A method and method of using a cable that includes a cable core. The cable core has an inner armor wire layer disposed thereabout. The inner armor wire layer has an outer armor wire layer disposed thereabout. The inner armor wire layer and outer armor wire layer have torque removed therefrom during manufacturing.
Claims17
A method of manufacturing a cable, wherein the method comprises:
- disposing an inner armor wire layer about a cable core;
- disposing an outer armor wire layer about the inner armor wire layer, forming the cable, wherein the cable is stretched and then has tension therein reduced as the cable is spooled onto a stretched cable drum, and wherein torque in the armor wire layers is removed during manufacturing by placing the stretched cable drum on a twister, and wherein the stretched cable passes from the stretched cable drum to a swivel sheave, from the swivel sheave to an intermediate sheave, and wherein twister twists the cable until the swivel sheave aligns with the intermediate sheaves, and then additional cable is spooled from the stretched cable drum, and wherein the foregoing is repeated until the residual torque is removed from the cable.
A method of running a tool into a wellbore, wherein the method comprises:
- connecting a downhole tool with a cable, wherein the cable is manufactured by:
- disposing an inner armor wire layer about a cable core;
- locking the inner armor wire layer in place using a polymer located about the cable core;
- disposing an outer armor wire layer about the inner armor wire layer, forming the cable;
- stretching the cable;
- reducing tension in the cable;
- and
- removing torque from the cable.
