Size:9 5/8" CHAMPPacker

Standard: NACE MR0175

Operate: ANNULAR PRESSURE OPERATED

Working condition: High pressure high temperature(HPHT)

Type: full bore drill stem testing
Application: Drill Stem Testing
product model:CHAMP Packer ,CHAMP V Packer,CHAMP IV Packer
Service:H2S, CO2

Briefly Introduce:
Based on RTTS packer, Champ packer makes improvement to add a concentric bypass, which can reducethe suction as the tools going into the well. The Champ packer can achieves the circulating below thepacker, and the other functions are the same with RTTS packer.

Working Principle and structure features:
The CHAMP IV Packer is a hookwall-type retrievable packer with concentric bypass. While going in the hole,the bypass is held open until slips are set by the J-Slot that controls the mechanical slips. The bypass isheld closed by a balancing piston, which uses work-string pressure to place a downward force on thebalancing coupling to prevent the bypass from being pumped open.

Each assembled tool includes the following components:

J-Slot mechanism

Mechanical Slips

Packer Element.

Hydraulic slips.

Company Introduction

Xi'an Kingwell Oilfield Machinery Co.,Ltdis an established, financially stable manufacturing company and manufactured products are technically qualified which match the highest quality & reliability standards. We fulfill all the requirements to become a reliable supplier of any National and International majors in this field.

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.

Quality Systems

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.
