Breaking Barriers: China’s Wellhead Equipment Technology Leads the Global Frontier of Energy Development
Recently Beijing — Deep in the heart of the Taklamakan Desert, China National Petroleum Corporation’s Tarim Oilfield has announced an encouraging breakthrough: its independently developed 175-megapascal ultra-high-pressure wellhead equipment series has successfully completed operations on six ultra-deep wells, setting a domestic record for wellhead pressure at 154.68 megapascals. This milestone marks China’s transition from “catching up” to “leading” in the development of equipment for oil and gas extraction under extreme operating conditions.
Technological Breakthrough: Breaking the Monopoly of Foreign Standards
For a long time, ultra-deep, high-pressure wellhead equipment has relied on imports, leaving core technologies subject to foreign control. Faced with the daunting challenges of “zero standards, zero technology, and zero experience,” Tarim Oilfield, in collaboration with industry partners such as Baoshi Machinery, spent three years overcoming key technical hurdles in material selection, sealing, and manufacturing for ultra-high-pressure wellheads. This series of equipment features a dual‑disc design, with critical components made from hydrogen‑embrittlement‑resistant alloy steel, capable of withstanding temperatures up to 380°C and extreme pressures. Its valve‑opening/closing life exceeds 100,000 cycles, representing a 40% improvement over imported products. In May 2025, the first domestically developed 175‑MPa gas‑production wellhead assembly was put into operation at the Tarim Oilfield, breaking the foreign technology monopoly and being selected for inclusion in the Zhongguancun Forum’s exhibition of achievements addressing major national needs.
Application Expansion: Comprehensive Coverage Across All Scenarios, from the Deep Sea to Hydrogen Energy
Technological breakthroughs are accelerating the expansion of application scenarios for wellhead equipment. In the South China Sea, China’s independently developed integrated subsea wellhead system has completed sea trials in the Wenchang area, reducing the construction cycle for deepwater drilling by 30%. In Pingdingshan, Henan, Asia’s first million-cubic-meter‑scale salt‑cavern hydrogen storage demonstration project employs domestically produced, highly sealed wellhead equipment, achieving 100% domestic sourcing of core components in the hydrogen‑storage sector. Meanwhile, at the Daqing Oilfield, an innovatively developed “spiral‑lift wellhead system,” leveraging wireless remote‑control technology, has boosted injection‑well testing efficiency by 60% and attained a 100% zero‑discharge rate for wastewater.
Industrial Upgrading: Building an Independent and Controllable Ecosystem
According to industry reports, China’s wellhead equipment market is projected to exceed RMB 20 billion by 2026, with the domestic substitution rate rising to 85%. Companies such as Xinjiang Jinshi Drilling & Production have achieved end-to-end independent control across the entire industrial chain, establishing five digital production lines; the CNC adoption rate for key components has reached 100%, and product precision meets API standards. Experts from the China Petroleum Exploration & Development Research Institute note that, as the “dual carbon” goals advance, specialized wellhead equipment with CO₂ corrosion‑resistance will emerge as a new growth driver, with the market size expected to surpass RMB 1.5 billion by 2030.
From the ten-thousand-meter-deep wells of the Tarim Basin to the azure waves of the South China Sea, China’s wellhead equipment, driven by independent innovation, is strengthening the nation’s energy security and contributing a Chinese solution to global energy development.
