Abstract
A downhole tool assembly has a sleeve with a continuous j-slot, a lug rotator ring configured to move axially relative to the sleeve and having a lug configured to move within the continuous j-slot, and a rupture disk configured to prevent the lug from moving within the continuous j-slot during run-in. A method of activating the downhole tool assembly includes lowering the downhole tool assembly into a well bore on a tool string, rupturing the rupture disk, allowing the lug to move within the continuous j-slot, and setting the downhole tool assembly by lifting upward and pushing downward on the tool string.
Claims7
A method of activating a downhole tool assembly comprising a sleeve having a continuous j-slot, a lug rotator ring configured to move axially relative to the sleeve and having a lug configured to move within the continuous j-slot, and lock comprising a shear pin and a locking portion configured to move separately from the lug between a locked position and an unlocked position, where the locking portion is in the locked position to block the lug from moving within the continuous j-slot during run-in, the method comprising:
- lowering the downhole tool assembly into a well bore on a tool string;
- shearing the shear pin, moving the locking portion separately from the lug to the unlocked position to unblock the lug and allow the lug to move within the continuous j-slot, wherein the locking portion is biased in the unlocked position by a biasing member;
- and
- setting the downhole tool assembly by lifting upward and pushing downward on the tool string.
