Solution

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.

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.

The Surface Safety Valve, together with the Wellhead Control Panel, forms the Wellhead Safety Control System.

Our Surface Safety Valve is a type of linear motion valve driven and controlled by pneumatic or hydraulic, and relied on spring reset. It is applied in oil and natural gas well fields to provide safety protection in critical situations such as oil and gas leakage or fire. It can directly and quickly shut off the wellhead.

This is a comprehensive testing machine specifically designed for testing specimens that use automotive coolant and have small pulse pressures, high pulse frequencies, and large expansibility, using a dynamic composite loading of internal pressure (P), external vibration (V), and (internal and external) temperature (T) to test the reliability of the specimens. It can also perform tests for flow rate (medium) and humidity (environment).
