Oil & Gas Equipment Solution

The MPD system mainly consists of a choke manifold control system, backpressure compensation system, remote monitoring system, and software system. The system integrates pressure monitoring and micro-flow monitoring functions. Through self-developed automatic control software, it can accurately control the downhole pressure, achieving managed pressure drilling.

The MPD system treats the wellbore as a closed pressure system and sets the control objective for the annular pressure at the bottom of the well according to the upper and lower limits of the safe pressure interval. By using drilling fluid density smaller than the formation pore pressure and applying automatic throttling backpressure control technology, the system manages the pressure throughout the wellbore in a closed loop, counteracting the pressure fluctuations generated by drilling, stopping pumping, adding or removing drill pipes, and other drilling operations, thereby effectively addressing complex drilling problems such as density window, pressure-sensitive formation leak-off, same-layer formation drilling, and borehole collapse.

Application objects/scenarios: oil and gas drilling operations.

The PR2 system consists of a high and low temperature environmental chamber, valve driving device (torque testing tool), water/gas pressurizing equipment, measuring and control system, and monitoring system. It can automatically conduct test for the pressure, temperature, and torque combined cycle tests specified by the PR2 standard. It meets the requirements of standards such as API 6A, ISO 10423, GB 10592.

Application objects/scenarios: The strength and sealing test of ram BOP, annular BOP, valve, hanger, Christmas tree and other wellhead products, the dynamic test of valve opening and closing at maximum/minimum temperatures, valve pressure/temperature cycling tests, torque tests, etc.

The BOP Testing System consists of the following components:

The BOP pressure testing unit： is used in conjuction with other systems to perform pressure fatigue test, hydrostatic test, ram closing test, tripping test. Also conduct the tests for hangers, packers,shears, seals, and control units.

The BOP leak testing unit: pressurizes the test target, and observes the pressure decline. it opens or closes the device by controlling different output circuits.

The seals temperature testing unit: verifies the performance of non metallic seals used as pressure-controlling and/or pressure containing during the exposure to low and high temperatures.

The data collection and monitoring system: monitors and controls the entire testing process and achieve fully automation control.

The 11D1 HPHT Validation Test System mainly consists of a high-pressure/ultra-high-pressure testing well for downhole tools, an intelligent high-pressure/ultra-high-pressure oil, gas, and water boosting system, a force loading testing device, a circulation heating and insulation device, and a remote central measurement and control system.

Application objects/scenarios:

It is mainly used to simulate the high-temperature and high-pressure environment of downhole tools such as packers and bridge plugs in actual working conditions. According to API 11D1 standard, V0 level verification tests are carried out, including gas tests, axial load tests, temperature cycle tests, and zero gas bubble acceptance standards for performance testing of packers and bridge plugs. It includes envelope curve verification tests for downhole tools, as well as pressure and temperature resistance tests for other instruments and tools that require high-temperature and high-pressure environment testing. At the same time, it provides testing means for the development of new downhole tools.

The control system that manages the manifold valves at the wellhead uses pneumatic-hydraulic/electro-hydraulic logic. It can meet the working requirements of various sizes of manifolds, maintain stable wellhead pressure, ensure the safety of wellhead production, protect wellhead equipment and pipelines, protect oil and gas resources and the environment, prevent pollution, and is easy to operate with stable performance, saving labor and reducing the labor intensity of outdoor operations.

It can remotely control the opening and closing of the hydraulic choke valve, and display the standpipe pressure, casing pressure, and valve position of the hydraulic choke valve on the control box to maintain the bottom hole pressure. It is necessary equipment for successfully controlling well kicks and blowouts, and implementing oil and gas well pressure control technology.

Application object/scenatios: control of various valves on the choke manifold.

This refers to a device used to test the gas-tightness of the threaded connection of an oil casing. After the connection is made, a high-pressure booster is used to pressurize a mixture of high-purity helium and hydrogen to the testing pressure. The upper and lower parts of the thread of the isolation tool form a closed space inside the oil casing, and the gas-tightness of the oil casing thread is tested using the characteristics of the small molecular weight and easy leakage of helium.

Application object/scenarios: gas-tight joint detection of oil casings.
