Cased Hole 5" 10000 PSI Rupture Disk Sampler Drill Stem Testing DST Tool
Introduction of the RD sampler
The rupture disk (RD) sampler is a sort of full bore sleeve sampler that is applied for drill stem testing service in oilfield. The RD sampler is controlled by a rupture disk that is operated by annulus pressure, used for trapping formation fluid under pressure in downhole.
Features and Benefits
* The operation pressure in the RD smapler is fixed and steady, that is controlled by high precise rupture disks.
* Full-open capabilities are retained after the tool has trapped its sample.
* Several samplers can be run on during the well testing service
* A test to allow sampling at different times.
* A piston pushing device is available, the trapped sample can be transported to other vessels to process PVT analysis under high pressure condition.
* One time operation, once the RD sampler is closed can not be open again, several samplers can be
run on if different testings needed.
