Liner Hanger Running Tool and Method |
摘要 |
A liner hanger running tool (10) and method are provided for positioning a liner in a well bore. A tool mandrel (24) is supported from a running string, and a housing (44) surrounds the tool mandrel. A flow annulus between the mandrel and the housing allows fluid to pass upward through the running tool to a position above the liner. A hydraulic release mechanism (78, 79) is activated by fluid pressure within the mandrel to axially move a piston (50) positioned radially outward of the mandrel to release the running tool from the liner.
