摘要:
A multi-position tool for use at a downhole end of a conveyance string for operation in a casing string is provided. The tool comprises a mandrel connected to the conveyance string; an actuation housing slidably shiftable axially along the mandrel between an uphole position, at least one intermediate position and a downhole position; an uphole device operable between an activated position when the actuation housing is in the uphole position, and a deactivated position; and a downhole device operable between an activated position when the actuation housing is in the downhole position, and a deactivated position. Both the uphole and downhole devices are in their deactivated positions when the actuation housing is in the at least one intermediate position. The tool has a J-slot mechanism operable between the actuator housing and the mandrel for shifting the actuator housing between the uphole, at least one intermediate, and downhole positions.
