VR Safety Joint For Drill Stem Testing Service 5" x10000psi
VR Safety joint is a compact, right-hand safety joint used in the
drill stem testing string. It is run immediately above the packer
assembly to ensure that a minimum number of tools are left in the
hole if it becomes necessary to release the safety joint. The
tool’s bypass feature acts as an auxiliary to the Hydrospring
tester bypass to allow fluid to pass though the packer while the
work string is being pulled out of the hole.
A spline and lug arrangement, joining the male and female parts of
the left-hand safety joint thread, lock to prevent unintentional
back-off from the tool during normal manipulation of the drill pipe
during testing. Because of the spline and lug configuration, the
slips must be dropped in place before the drill pipe is lowered
after every stand of pipe is pulled out of the hole.
