Multi shot activation system

摘要

An activation assembly for a wellbore tool positionable in a wellbore includes a housing, a wellbore tool coupled to the housing, and a tool activator operatively coupled to the wellbore tool. The tool activator includes first and second fixedly connected circular disks, each of which includes a plurality of radially projecting teeth disposed around an outer circumferential surface of the disk. The disks are rotatably mounted about a longitudinal axis of the housing. The tool activator further includes a key member having a head portion engageable with the teeth of the first and second disks. The key member is located within the housing such that the disks rotate through a limited angular distance in response to movement of the key member.

1. An activation assembly for a wellbore tool positionable in a wellbore, said assembly comprising:
a housing including an internal flow passage; a wellbore tool coupled to the housing; and a tool activator operatively coupled to the wellbore tool and located within the internal flow passage of the housing, the tool activator including:
first and second fixedly connected circular disks, each disk including a plurality of radially projecting teeth disposed around an outer circumferential surface of the disk, said disks rotatably mounted about a longitudinal axis of the housing; anda key member including a head portion, the key member located within the internal flow passage such that the disks rotate through a limited angular distance in response to movement by the key member between a first position, where the head portion of the key member is engageable with the teeth of the first disk, and a second position, where the head portion of the key member is engageable with the teeth of the second disk.
