摘要： This invention relates to a method for recovering a tubular structure (3) from a well (1), wherein a so-called free point is defined as the location where the tubular structure is stuck in the well. The method comprising providing a downhole tool string comprising a pipe-severing tool and an upper part of the downhole tool string; lowering the downhole tool string into the tubular structure to release the free pipe. Before the step of triggering the pipe-severing tool to sever the tubular structure, the method includes releasing the pipe-severing tool and subsequent withdrawing the upper part, of the downhole tool string away from the free point towards the surface over at least a predefined distance. The invention relates to a downhole tool string for use in such method.

摘要： The invention relates to a downhole tool (10) for use in a casing or tubing (99) in a well comprising a support (15) and a brush (12). The downhole tool (10) further comprises a lever arm (13) having a first end (13-1) and a second end (13-2) opposite the first end (13-1). The lever arm (13) is pivotably mounted to the support (15) and the brush (12) is mounted at the second end (13-2) of the lever arm (13). A driver means is provided for driving the lever arm (13) outwardly to press the brush against a wall of the casing or tubing (99) in operational use of the downhole tool (10). An advantage of the invention is that one size of the downhole tool may fit all sizes of a casing or tubing. The invention also relates to method of cleaning and honing casings or tubings in a well.

摘要： This invention relates to a method for activating and deactivating a GS-tool (2) having grippers (22), tool housing (32), spindle (22), and main spring (50) arranged to pre-tension the gripper (44) towards a deactivated position as the GS-tool (2) is displaceable in a wellbore (10) in the ground. The method includes the steps of coupling the spindle (22) of the GS-tool (2) to an actuator mandrel (12) of an actuator (4); arranging an activating sleeve between the tool housing (32) and an actuator housing (14); and displacing the actuator mandrel (12) and thereby the spindle (22) relative to the tool housing (32) in a direction from the GS-tool (2) until the grippers (44) have reached activated positions by overcoming the force from the main spring (5). A GS-tool for implementing the method is also described.
