Why Choose SJ Petroleum Machinery?

🏭 Sinopec Manufacturing Heritage

We're not a trading company – we’re a manufacturer with roots in Sinopec's engineering ecosystem. Founded in 1941, we’ve been building oilfield equipment for over eight decades. As a China Critical Technological Equipment Nationalization Base and National Hi-tech Enterprise, our quality systems, supply chains, and engineering standards meet the highest benchmarks.

🔧 Full-Spectrum Engineering Capability – 100% Independent

From injector head to control cabin, we design and build every major component in-house. We have mastered heavy-load injector heads, large-capacity quick-change reels, automated control systems, and integrated modular designs. The SLG630D has been recognized as the world's first all-electric drive automated coiled tubing unit.

🎯 Automation Pioneer – China’s First "One-Key” CTU

We developed "一键式” ("one-key”) automation for coiled tubing units, achieving automatic pipe running and retrieval, automatic pipe spooling, and automatic lubrication with a 30% efficiency improvement. The system features three automatic drilling modes that reduce drilling time by 50%.

🌍 Proven Global Track Record

After nearly 20 years of continuous development, SJ's coiled tubing units have been exported to the Middle East, South America, Africa, Russia, and other international markets. The SLG630 has been field-proven in the Puguang Gas Field at 6,121 meters and has successfully completed side-tracking horizontal well operations.

⚡ Field-Proven Performance – The Largest in Domestic Use

The SLG630 is currently the largest-capacity coiled tubing unit in domestic use in China, with a maximum pulling force of 62 tonnes and maximum tubing capacity of 2″ × 8,000 meters. The SLG630D (all-electric) offers 30% lower energy cost and 10% noise reduction compared to diesel-hydraulic equivalents.
