In the process of vigorous development of the oil and gas extraction industry, the choke manifold control panel, as a key equipment to ensure the safety and efficiency of operations, has always occupied an indispensable position. Guangzhou Dongsu Petroleum D&E Equipment Co., Ltd. (Dongsu), with its deep accumulation and outstanding contributions in this field, has become an important force in promoting the progress of the industry.
Dongsu has been engaged in the research and development, design and manufacturing of key oil and gas equipment such as ground blowout preventer control systems, pneumatic pressure testing devices, and choke manifold control panels since the early 1980s. The company has an elite technical team of more than 30 senior engineers who are experienced in product technology research and development, design analysis, etc., providing solid intellectual support for the continuous innovation and optimization of the choke manifold control panel.
The choke manifold control panel can operate stably, relying on a set of precise and efficient working mechanisms.
Data acquisition: Sensors are like the "sensing tentacles" of the control panel, distributed at key positions of the wellhead and choke manifold system. Pressure sensors, temperature sensors, flow sensors, etc. each perform their duties, capturing the changes in parameters such as pressure, temperature, and flow in the system in real time, and quickly converting these physical signals into electrical signals or other convenient signal forms for transmission, and transmitting them to the control system.
Data analysis and command generation: The control system is the "smart brain" of the entire device. After receiving the signal from the sensor, it will quickly and accurately analyze and process the data according to the preset program and safety threshold. Once a parameter abnormality is detected, such as the wellhead pressure exceeds the normal range, the control system will immediately calculate the throttle opening that needs to be adjusted and issue precise control instructions to the actuator.
Command execution: The actuator is the "executor" of the control system command, mainly composed of various valves and pumps. After receiving the command, the actuator responds quickly, by adjusting the opening of the throttle valve, changing the flow area of the fluid, thereby achieving precise control of parameters such as wellhead pressure and flow. For example, when it is necessary to reduce the wellhead pressure, the actuator will increase the throttle valve opening to allow more fluid to pass smoothly, thereby reducing the wellhead pressure and maintaining the bottom hole pressure balance.
Relying on Dongsu's strong strength, the throttle manifold control panel stands out in the field of oil and gas extraction with its series of outstanding features.
High reliability and stability: The design and manufacturing strictly follow high standards, with high reliability, can operate stably in complex and harsh working environments, reduce the frequency of failures, and provide strong guarantees for the continuity of oil and gas extraction operations.
