RTTS Circulating Valve Downhole Oil Tools Drill Stem Test Tools 9
5/8"
Introudction of RTTS Circulating Valve
The 9 5/8" RTTS Circulating valve is the retrievable circulating
valve designed with full bore feature. The RTTS circulating valve
is a part of the drill stem testing string used for well testing
service and flow operation. The circulating valve is with
ocked-open/locked-closed valve, so the circulating valve serves as
both a circulating valve and bypass.
Features and Benefits of the RTTS Circulating Valve
* With the feature of full bore, the tubing-type guns and wire line
equipment can be passed through the
RTTS circulating valve.
* To reduce the effect of fluid-swabbing action when the RTTS
circulating valve is run in
* The circulating valve can serve as the bypass.
Operation of RTTS Circulating Valve
The Multifunctional circulating valve is automatically locked in
the closed position when the packer is set. During testing and
squeezing operations, the lock helps prevent the valve from being
pumped open. A straight J-slot in the locked-open position can be
used with the straight J-slot(optional) in the packer body. This
combination eliminates the need to turn the tubing to close the
circulating valve or reset the packer after the tubing has been
displaced with cement.
The Multifunctional circulating valve can be run directly above the
packer body or further up the work string.
