Geothermal well head clean out and shut off assembly

摘要

An assembly for cleaning deposited minerals from the interior passages of first and second axially aligned tubular laterals that extend outwardly in opposite directions from a geothermal well head and removably support first and second gate valves from the free ends thereof. The cleaning of the passages in the tubular laterals as well as passages in the first and second gate valves may be conducted with the assembly without killing the well. The assembly also permits a third vertically disposed gate valve on the well head to be removed for repair and maintenance purposes without killing the well, and this is also possible with the first and second gate valves.
