A sliding sleeve assembly for opening the setting port of a hydraulically set well packer which may be positioned for actuation in either an upwardly or downwardly direction. A shearable plug initially blocking the setting port and positioned in an elongate recess in the packer which extends equal distances on either side of the setting port with a shoulder at each end of the recess and a sliding sleeve telescopically positioned in the recess and in engagement with the plug whereby when the sleeve is longitudinally moved the plug is sheared. The sleeve including two actuation shoulders facing in opposite directions for moving the sleeve in either direction. The shoulders at the ends of the recess being tapered for retracting a setting tool after the sleeve is shifted in the recess.
