摘要 |
Disclosed is a side entry sub with tension release wireline cable clamp. The side entry sub includes a tubular member having a port for the passage of the wireline cable into the interior of the tubular member. A cable clamp holder is positioned on the tubular member adjacent the port. The cable clamp holder has an axially extending passage with a cable clamp mounted therein. The cable clamp includes two clamp parts that are adapted to grip the cable therebetween. The cable clamp parts are movable from a gripping position to a releasing position responsive to axial movement with respect to each other in the clamp holder passage.
