Round Mandrel Slip Joint For DST service Fracturing Service
The Round Mandrel Slip Joint is the part of drill stem testing tool string, the slip joint accepts the movement associated with ocean heave or temperature change without allowing the movement to disturb the placement of downhole tools.
The round mandrel slip joint has the following characteristics:
• Top of the mandrel slip joint has 4 3/4-in. (120.65-mm) drill collar profile for easy handling with the rig elevators and slips
• Maintains its full tensile rating when collapsed and locked
• Can be locked in the closed position for handling, reducing the risk of damage to the lifting/sealing mandrel
• Internally pressure and volume balanced
• String can be picked up with the slip joint locked; the slip joint can then be unlocked before it is run into the hole
• Provides free travel in the string to reciprocate tools without unseating the packer
