Wireline running tool

摘要

A wireline running tool enables a module to be lowered into or removed from a production tubing or pipe line, especially one extending downhole in an oil or gas well. A kickover arm in the tool deflects the module into a side pocket in the tubing or pipe. The power for so deflecting such module comes from a pressurized pneumatic cylinder. If something goes wrong and the tool or module becomes stuck in the tubing or pipe, the gas slowly leaks from the pneumatic cylinder, after which the tool or module becomes unstuck.
