Rupture Disk Sampler RD Sampler For Drill Stem Testing Service
The Rupture Disk Sampler is a full-open, full bore sleeve sampler
for use on drill stem tests. The RD sampler isused for trapping
formation fluid under pressure in downhole. The sampler is
controlled by a pressure-operated rupture disk and has a sample
mandrel with a built-in differential area. To catch a sample,
annulus pressure is increased to a predetermined level, the rupture
disk in the sampler breaks, and the mandrel traps the sample.
When the rupture disk breaks, the differential area of the sample
mandrel is exposed to an air chamber on one side and hydrostatic
pressure and applied annulus pressure on the other. This condition
results in the sample mandrel moving up and trapping the sample.
When the sample mandrel reaches the top of its stroke, it is locked
in place by a set of locking dogs
