Oil Well Donwhole Well Testing Equipment Rupture Disc Sampler 10000psi

Oil Well Donwhole Testing Rupture Disc Sampler / DST RD Sampler

The rupture disk sampler / RD sampler is one of drill stem testing tools, it is designed with a full-open, full bore sleeve type used in downhole testing service.The RD sampler is controlled by a rupture disk that is operated by annulus pressure.

Features

• Time-delay feature of Rupture Disc Sampler allows the sample to be trapped after a preset time. Different metering cartridges can be used to vary the closing time.
• Full-open capabilities are retained after the RD sampler has trapped its sample.
• Several samplers can be run on a test to allow sampling at different times.

Operation

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 nonmonophasic (bulk) samples.

ZZ TOP Oil Tools Co., Ltd located in XI’AN City in China, is in full service on design, production and supply of oilfield downhole tools and Wellhead Equipment from 2010.
