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. We don't just assemble – we engineer. The SLG630 project has been recognized as China’s first automated SLG630 coiled tubing unit.
🎯 Automation Pioneer – China's First "One-Key” CTU
We developed China’s first "一键式” ("one-key”) automated coiled tubing unit. Our fully electro-hydraulic control system with integrated network control represents the cutting edge of coiled tubing automation.
🌍 Proven Global Track Record – Exporting Worldwide
After nearly 20 years of continuous development, SJ's coiled tubing units have been exported to the Middle East, South America, Africa, Russia, Indonesia, and other international markets. The SLG630 has been field-proven in the Puguang Gas Field at 6,121 meters and has successfully completed 侧钻水平井 (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.

Frequently Asked Questions (FAQ)
Q1: What does the "T” in SLG630T stand for?
A: The "T” stands for trailer-skid hybrid – a configuration that combines the road-towable mobility of a trailer with the modular, crane-friendly nature of skid-mounted components. This allows the unit to carry massive tubing reels while maintaining transportability across challenging terrain.
Q2: What’s the pulling capacity of the SLG630T?
A: The SLG630T delivers 620 kN (140,000 lbs / 62 tonnes) of continuous pulling force. This is the highest-capacity coiled tubing unit in the SLG series and the largest-capacity unit in domestic use in China.
Q3: What tubing capacity does the SLG630T handle?
A: The SLG630T is equipped with a large-capacity tubing reel that holds 2″ tubing to 8,000 meters. For long horizontal wells and high-flow-rate operations, the unit can be configured with 2-3/8″ tubing to 7,000 meters.
Q4: What does "trailer-skid hybrid” transport mean?
A: The SLG630T uses a "车+拖”组合移运方式 ("car + trailer” combo transport) that achieves efficient site-to-site transfer and rapid installation. The system is designed for modular transport that adapts to different road conditions. Whether you're moving across paved highways or unpaved wellsite roads, the SLG630T gets there – and gets to work fast.
Q5: Does the SLG630T support automation?
A: Yes. The SLG630T supports "一键式” ("one-key”) automation with three automatic drilling modes that reduce drilling time from 2–4 hours to 0.5–1 hour – a 50% efficiency improvement. The system also features adaptive control pressure adjustment that intelligently identifies and intervenes in slip drilling situations.
Q6: Has the SLG630T been proven in the field?
A: Yes. The SLG630 has been field-proven in the Puguang Gas Field at 6,121 meters and has successfully completed 侧钻水平井 (side-tracking horizontal well) operations. In the Shengli Oilfield, SLG630 equipment has demonstrated cumulative operation mileage reaching millions of meters.
Q7: Is an all-electric version available?
A: Yes. SJ has developed the 全电驱 SLG630 (all-electric drive SLG630) which features automatic running, automatic drilling, and emergency handling functions. The electric version offers 30% lower energy cost and 10% noise reduction compared to diesel-hydraulic equivalents.
Q8: What's the typical lead time for an SLG630T?
A: Standard lead time is 120 to 180 days from order confirmation to shipment, depending on configuration and customization level. Contact our sales team for current availability.
Q9: Do you provide training and after-sales support?
A: Absolutely. Each SLG630T sale includes commissioning assistance and operator/maintainer training – either at your facility or ours. Spare parts are stocked for global shipment, and our technicians are available for field support.
Q10: How do I get a quote for an SLG630T?
A: Send us your well parameters: target depth, tubing diameter, expected wellhead pressure, operating environment, and preferred configuration (trailer-skid, truck-mounted, skid-mounted, or all-electric). We'll respond with a technical proposal and commercial quote within 7–10 business days.
