Abstract:
A pipe setting tool includes a tool shaft, a coupler mounted on a first end of the tool shaft, and a tool sleeve affixed to the tool shaft defining a space therebetween. An outside diameter of the tool sleeve ensures close conformity to a borehole to position a geothermal pipe mounted thereto in close proximity to the outside diameter of the borehole. A moveable seal cap may be mounted on the tool shaft, moveable between a first position spaced-apart from the tool sleeve during down-hole movement of the tool to permit fluid flow through the space and a second position against the tool sleeve during up-hole movement of the tool to establish a seal with the tool sleeve to prevent fluid flow through the space. A second end of the tool shaft may receive a pipe hook to attach a geothermal pipe to the pipe setting tool.
