Solution

For wellheads that require high reliability and programmable logic control, FST has developed the PLC-based wellhead control system. The system is designed with advanced fault-tolerant, fail-safe programmable logic controllers, internationally certified safety I/O modules, simplex/redundant configurations, and communication modules for intelligent control of the wellhead.

Power sources: manual hydraulic pumps and electric hydraulic pumps.

Control objects: surface safety valves and subsurface safety valves.

Applicable working conditions: wellheads that require high reliability and programmable logic control.

For areas where power supply is unavailable in desert and remote regions, FST has developed a solar-powered wellhead safety control system that uses solar energy as a power source. For natural gas reservoirs, a gas wellhead safety control system can also be designed to use natural gas as a power source in order to reduce costs.

Considering the difficulty of inspecting wells in person in desert and remote areas, these types of wells are remotely controlled and monitored by RTU.

Power source: solar energy, electric hydraulic pump.

Control objects: subsurface safety valves, surface safety valves, etc.

Applicable working conditions: unmanned areas in remote areas such as deserts, Gobi, mountains, etc.

Highly intelligent and integrated system capable of controlling more than 30 wells.

Widely applicable in various environments, including high-temperature and high-pressure, extreme cold, corrosive salt spray environments on offshore platforms, hydrogen sulfide-enriched environments, etc.

Recognized and widely used in both international and domestic markets.

Control pressure up to 30,000 PSI, with integrated hot standby redundant RTU control system.

Suitable for high-risk harsh environments such as high temperature, high pressure, and hydrogen sulfide riched content, providing guarantee for the development of domestic HPHT H₂S-enriched gas wells.

Received unanimous recognition and long-term stable application in international and domestic markets.

FST has experience in leading the design, construction, and overall solution development of multiple national-level laboratories, and has obtained relevant patents.

FST represents the top tier of the technology in the construction of high-temperature and high-pressure laboratories in China, and is a leader in the construction of hig-temperature and high-pressure laboratories in China's oil and gas industry.

Provided important technical support for the sealing testing of China's fifth-generation fighter jets.

Helped solve the bottleneck technology problem in the testing of alloy zirconium tubes, promoting the localization of key technologies and equipment in the military and nuclear industries.

Promoted the implementation of the National 863 Program.

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.

Based on the characteristic of centralized control of multiple oil/gas wells on the ocean, FST has developed a multi-well wellhead safety control system, which contains multiple wellhead control modules. Each control module controls one well independently without interference, which facilitates maintenance and replacement.

The control system can be designed according to customer requirements as pneumatic-hydraulic, electric-pneumatic, electric-hydraulic systems with remote control interfaces.

Power source: manual hydraulic pump, electric hydraulic pump, pneumatic hydraulic pump.

Control objects: surface safety valve and subsurface safety valve, etc.

Applicable working conditions: oil and gas wellheads on offshore platforms.
