Surge immune liner setting tool |
摘要 |
A setting tool for hanging a tubular string includes: a tubular mandrel having an actuation port formed through a wall thereof; a debris barrier for engaging an upper end of the tubular string; and a piston having an upper face in fluid communication with the actuation port. The setting tool further includes: an actuator sleeve extending along the mandrel and connected to the piston; a latch releasably connecting the debris barrier to the actuator sleeve and for releasably connecting the debris barrier to the tubular string; a packoff connected to the mandrel below the piston and operable to seal against an inner surface of the tubular string, thereby forming a buffer chamber between the debris barrier and the packoff; and a passage. The passage: is in fluid communication with a lower face of the piston, is formed in a wall of and along the mandrel, and bypasses the packoff. |

1. A setting tool for hanging a tubular string from a liner string, casing string, or wellhead, comprising:
a tubular mandrel having an actuation port formed through a wall thereof; a debris barrier for engaging an upper end of the tubular string; a piston disposed along the mandrel, having an upper face in fluid communication with the actuation port, and operable to stroke the debris barrier relative to the mandrel, thereby setting a hanger of the tubular string; an actuator sleeve extending along the mandrel and connected to the piston; a latch releasably connecting the debris barrier to the actuator sleeve and for releasably connecting the debris barrier to the tubular string; a packoff connected to the mandrel below the piston and operable to seal against an inner surface of the tubular string, thereby forming a buffer chamber between the debris barrier and the packoff; and a passage in fluid communication with a lower face of the piston, formed in a wall of and along the mandrel, and bypassing the packoff. |
