Slips |
Wedge-shaped pieces of metal with teeth or other gripping elements that are used
to prevent pipe from slipping down into the hole or to hold pipe in place.
Rotary slips fit around the drill pipe and wedge against the master bushing to
support the pipe. Power slips are pneumatically or hydraulically actuated
devices that allow the crew to dispense with the manual handling of slips when
making a connection. Packers and other down hole equipment are secured in
position by slips that engage the pipe by action directed at the
surface.
