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. The SLG450T's injector head, tubing reel, control system, and other key components are all independently designed and manufactured by SJ. We don’t just assemble—we engineer.

🎯 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. We continue to advance automation and network control in coiled tubing equipment.

🔇 Silent-Tech Innovation – Quiet Operations, Happy Crews

SJ has successfully developed and applied 静音隔噪技术 (silent noise-reduction technology) to SLG450T units exported to Africa, achieving effective noise reduction in the operator cabin and significantly improving the working environment.

🌍 Proven Global Track Record

SLG450 units have been deployed across China's major oilfields (Fuling, Weiyuan, Shengli, Puguang) and exported to Saudi Arabia, Africa, Russia, and other regions. In Saudi Arabia’s Udlia block, the SLG450 successfully completed its first induced injection production operation, earning positive feedback from the user, particularly Saudi Aramco.

📊 Field-Proven Performance – 120+ Jobs, 3.6 Million Meters

In 2024 alone, a single SLG450 unit in the Shengli Oilfield completed over 120 well intervention jobs with a maximum depth of 4,965.3 meters and cumulative operation mileage of 3.6 million meters. The SLG450 has also successfully completed plug drilling operations at 6,121 meters in the Puguang Gas Field.

Frequently Asked Questions (FAQ)

Q1: What does the "T” in SLG450T stand for?

A: The "T” stands for "拖挂” (trailer-mounted) , indicating that this is a trailer-mounted integrated configuration. Unlike truck-mounted units, the SLG450T is designed to be towed to location and requires no on-site pipe threading or cable connections.

Q2: What's the pulling and snubbing capacity of the SLG450T?

A: The SLG450T delivers 450 kN (100,000 lbs) of continuous pulling force and 225 kN (50,000 lbs) of continuous snubbing force. These are continuous ratings, not peak—you can rely on these numbers for sustained operations.

Q3: What tubing sizes does the SLG450T handle?

A: The SLG450T handles tubing from 50.8 to 73.0 mm (2″ to 2-7/8″) . Reel capacity is customized per your depth requirements.

Q4: How fast can the SLG450T be rigged up?

A: Because the SLG450T requires no on-site pipe threading or cable connections, wellhead installation is achieved within 1 hour. This is significantly faster than conventional coiled tubing units that require extensive on-site assembly.

Q5: What does "one-key” automation mean?

A: The SLG450T supports "一键式” ("one-key”) automation—China's first automated coiled tubing unit. Operators can achieve automatic pipe running and retrieval, automatic pipe spooling, and automatic lubrication by simply setting input parameters. The system includes three automatic drilling modes that reduce drilling time from 2–4 hours to 0.5–1 hour—a 50% efficiency improvement.

Q6: Is a silent-tech option available?

A: Yes. SJ has successfully developed and applied 静音隔噪技术 (silent noise-reduction technology) to SLG450T units, achieving effective noise reduction in the operator cabin. This is particularly valuable for operations in noise-sensitive areas or residential proximity.

Q7: Has the SLG450T been proven in the field?

A: Yes. SLG450 units have been deployed across China's major oilfields and exported to Saudi Arabia, Africa, and Russia. In 2024 alone, a single SLG450 unit in the Shengli Oilfield completed over 120 well intervention jobs with cumulative operation mileage of 3.6 million meters. The unit has also successfully completed plug drilling operations at 6,121 meters in the Puguang Gas Field.

Q8: Are the core components independently manufactured?

A: Yes. The SLG450T's injector head, tubing reel, control system, and other key components are 100% independently designed and built by SJ.

Q9: What’s the typical lead time for an SLG450T?

A: Standard lead time is 90 to 150 days from order confirmation to shipment, depending on configuration and customization level. Contact our sales team for current availability.

Q10: How do I get a quote for an SLG450T?

A: Send us your well parameters: target depth, tubing diameter, expected wellhead pressure, operating environment, and any specific requirements (silent-tech, data acquisition, etc.). We'll respond with a technical proposal and commercial quote within 7–10 business days.
