OSTI ID:6127007
This patent describes an apparatus for locking a packer in a run-in position and preventing premature actuation of the packer in a wellbore. It comprises: a sleeve connectable to an outer portion of the packer; mandrel means disposed in the sleeve for connecting to an actuating mandrel of the packer; a locking member having a portion adjacent to the sleeve. The locking member being longitudinally and rotatably fixed with respect to the mandrel means; a lug extending from one of the sleeve and locking member; lug receiving means on the other of the sleeve and locking member for receiving the lug therein when in a locked position such that relative longitudinal movement between the mandrel means and the sleeve is prevented; and lock disengaging means for disengaging the lug from the lug receiving means at a predetermined position in the wellbore, thereby allowing relative longitudinal movement between the mandrel means and the sleeve.
