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.
