Method And Device For Activating And Deactivating A GS-Tool

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.

1. Method for activating and deactivating a GS-tool (2) wherein the GS-tool (2) in addition to grippers (44), a tool housing (32) and a spindle (22) comprises a main spring (50) arranged to pre-tension the grippers (44) towards a deactivated position, as the GS-tool (2) is displaceable in a wellbore (10) in the ground, the method comprises the following steps:
coupling the spindle (22) of the GS-tool (2) to an actuator mandrel (12) of an actuator (4); arranging an activating sleeve (16) connected to an actuator housing (14) between the tool housing (32) and the 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) whereby the tool housing (32) is brought to impact with the activation sleeve (16), and displacing the actuator mandrel (12) further until the grippers (44) reached the activated positions by overcoming the a force from the main spring (50).
