Round Mandrel Slip Joint Drill Stem Test Tools Cased Hole 5" 15000
PSI
Introudction of DST Slip Joint
The Round Mandrel Slip Joints are designed in full bore type which
are the APR Tools for the well testing operation. The slip joints
are available to move without allowing the movement to disturb
the placement of downhole tools. So when the down hole
temperature and pressure change, resulting in a change in the
string length, it will use the slip joint to finish the
opertion. If required to increase
the travel length, the multiple Slip Joints can be used in the
hole. And the slip joint is hydraulically balanced and
is insensitive to tubing pressure.
Characteristics of the Round Mandrel Slip Joint
* The mandrel slip joint has 4 3/4-in.drill collar profile on top,
that is easy for handling with the rig elevators and slips
* When collapsed and locked, full tensile rating of slip
joint will be maintained
* The slip joint can be locked in the closed position for handling,
taht can reduce the risk of damage to the lifting/sealing
mandrel
* The slip joint can be unlocked before it is run into the hole.
* String can be picked up with the slip joint locked;
• Without unseating the packer, the slip joint provides free
travel in the string to reciprocate tools
Features and Benefits of the Round Mandrel Slip Joint
* The slip joint provides a variable-length joint to allow the pipe
to expand during well testing operation.
* Slip joint keeps vertical movement from disturbing tool placement
* During testing or stimulation, the slip joint provides a constant
weight on the packer
