DST Tools Rupture Disc Sampler Full Bore Sleeve Sampler For Oil Well Testing
The Rupture Disk sampler is one of Drill stem testing tool string, the rupture disk sampler is a full-open, full bore sleeve sampler and controlled by the annulas pressure. The RD sampler featured with full-open capabilities which are retained after the tool has trapped its sample. And Several samplers can be run on during the well testing operaion. In one time operation, once the RD sampler is closed can not be open again, several samplers can be run on if different testings needed.
Operation of RD sampler
The RD 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.The 1,200-cc sample chamber allows a sufficient sample for two 500-cc non- monophasic (bulk) samples.
