摘要： Providing hydraulic fluid from a hydraulic pump to a tool connected to respective first and second ends of a wellbore linear actuator and such an actuator. The actuator has a double acting cylinder with a cylinder head, a cylinder cap opposite the cylinder head, a piston head, and a piston rod. The piston head separates the cylinder into a first chamber and a second chamber, and the piston rod extends out of the second chamber through the cylinder cap. The double acting cylinder has first and second ends, and the double acting cylinder further includes a feed fluid passage between the first and second ends, wherein the feed fluid passage includes a first fluid line through the piston head and the piston rod, the first chamber, and a second fluid line through the cylinder head. The double acting cylinder is configured for preventing said piston rod from rotating relative said cylinder bore.

摘要： A drum unit for an intervention string for a well includes a drum with a drum axis and with a radius, arranged in a structural frame and rotatable by a motor and a tension compensator. The tension compensator includes a guide arch displaceable in a direction generally along the intervention string, orthogonal to the drum axis, using a first force device connected to the structural frame for keeping the intervention string in tension. At least a first end of the guide arch is laterally displaceable in a direction generally orthogonal to the intervention string, parallel with the drum axis. The intervention string runs between the guide arch to or from the first end to the drum. The intervention string runs via a second, opposite end of the guide arch via a second, fixed guide at the structural frame, directly or indirectly to or from the well.
