| 摘要 | A shifting tool can include an inner mandrel, engagement members engageable with a well tool component, and a detent device that prevents relative displacement between the inner mandrel and the engagement members, but permits such relative displacement in response to a predetermined longitudinal force. A method of operating a shifting tool can include engaging engagement members with a component of a well tool, and disengaging the engagement members from the component by applying a predetermined longitudinal force, thereby causing the engagement members to retract out of engagement with the component and then extend in the well. Another shifting tool can include a retraction sleeve, engagement members that engage a well tool component, and a detent device that prevents relative displacement between the retraction sleeve and the engagement members, but permits such relative displacement in response to a predetermined longitudinal force. | ||||||
