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

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.
