DST Tools 5" Rupture Disk (RD) Sampler Drill Stem Testing
product model: 5" Rupture Disk (RD) Sampler
Usage: Drill stem testing
Type: full-open, full bore sleeve sampler
Working condition: High pressure, High temperature(HPHT)
Working pressure: 10000psi ~ 15000psi
The rupture disk sampler is a full-open, full bore sleeve sampler for use on drill stem tests. The sampler is controlled by a rupture disk that is operated by annulus pressure.
Features and Benefits
• Time-delay feature 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 tool has trapped its sample.
• Several samplers can be run on a test to allow sampling at different times.
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.
The 1,200-cc sample chamber allows a sufficient sample for two 500-cc nonmonophasic (bulk) samples.

Xi'an Kingwell Oilfield Machinery Co.,Ltd is a professional supplier for oilfield products according to the API standard.
Our products have exported to USA, Canada, Egypt, India and UEA, etc with 40 FCL containers per month. Now, with high quality and short supply and good service, our products have got good reputation home and abroad .
Here we got some prise as follows
Design & Development
Kingwell has an ongoing relationship with Xi'an Petroleum University and built up long term cooperation with China Aerospace Group for more than 10 years. Design Department is familiar with CAD and Pro-E facilities and has on rolls qualified & experienced engineers. Now, they are engaged in development of new products as required in the market place. Kingwell' products are validated in-house in a Test Well, a Sub-surface Type Test Facility with simulated well conditions up to 15000 psi Differential pressure , 400°F and Max 450°F.
A well-established Quality System from Materials receipt to Products delivery ensures consistent quality at all levels of the activity. QMS Procedures & Measurements are tailored to establish high standards of Quality Assurance in the Operations. The Company maintains the 100% Traceability records as per API requirements &NACE MR 0175-2002 Standards and complies with all the legal, statutory and regulatory requirements.
1\Quality control of the raw material:
1)The selection of the raw material supplier:our raw materials mainly include alloy structural steel, stainless steel, non-ferrous metal alloy and high nickel alloy, etc, in the selection of the raw material suppliers, we would do the comprehensive assessment of the supplier strictly according to technical requirements .Most of our suppliers are the leading enterprises of the steel production in China and the special alloy are usually purchased from abroad to ensure a higher mechanical properties.
2) The acceptance & Inspection of the raw material:
Ultrasonic flaw detection for every piece of the steel.
Chemical composition analysis for every piece of the steel.
Mechanical performance test for every piece of the steel..
2\Quality control of the seals:
1) O Rings: 100% visual and dimensional inspection for every piece of the O-rings, 15% spot check for the size and hardness test of the o rings. As for the sealing and heat resistance properties of the o rings, we designed a special test device which is equipped with heating insulation equipment that can simulate the down hole temperature and pressure. At present, our fluorine can keep a good performance in the condition of 210 ℃, and 105 Mpa work pressure (maximum pressure ever reached 146).
2) Back-up ring: 100% visual and dimensional inspection for every piece of the back-up ring, as for the test of the sealing and heat resistance, we design and manufacture the special test device, equipped with heating insulation equipment to stimulate the down hole temperature and pressure for acceptance. At present, our company's high pressure back-up seal can keep good sealing performance and deformed a little in the condition of 210 ℃, and 105Mpa work pressure (maximum pressure ever reached 146). It can be used for many times.
3. Quality control of the spring: Apart from the conventional test of the raw material and size of the different springs that used in the tools, we specially designed a test device that equipped with heating preservation equipment to stimulate the down hole temperature and condition to test the spring performance.
4. Quality control of the spare parts processing:
1) Spare parts processing control:In strict accordance with the process and traceability requirements, a test, mark and record of dimension, geometric tolerance and for every piece and every procedure will be conduct.
2) Heat treatment quality control: We have two high temperature heat treatment furnaces that are mainly used for stainless steel and other special material heat treatment. For other materials, we entrust Baoji Petroleum Machinery Company Heat Treatment Plant to do the heat treatment. For the inspection of the heat treatment, we are equipped with the special inspection machine such as gantry hardness tester, digital universal tensile tester etc.
5. Quality control of the tool assembly and testing process
1) Test equipment: in addition to the conventional hydraulic test pump, tensile testing machine, we also have a pressure sensor and data acquisition system which can accurate and clear record each step of the test.
2) Technical documents: We have a test acceptance list for every tool test that clearly guides the each step of the test.
3) Assembly test: A special inspector will supervise the whole assembly process.
