Oil Well Testing RD Sampler for High Pressure Drill Stem Testing Service
Overview of the Rupture Disk Sampler
The rupture disk sampler is short of RD sample, is a kind of full-open dst tools applied for downhole testing service.The RD sampler with the full bore sleeve sampler is controlled by a rupture disk that is operated by annulus pressure, used for trapping formation fluid under pressure in downhole.The Rupture Disc Sampler provide the method to captureg a well fl uid sample for retrieval and analysis on surface.When run with the Infl ate or Mechanically Operated string the sample will be caught at the end of the fi nal fl ow at fl owing pressure.When run with the Compression string the sample will be caught at the end of the final shut in at shut in pressure.
