Individual skids can be lifted separately, reducing the required crane capacity at each lift
Modules can be positioned independently around the wellhead for optimal layout—critical on space-constrained offshore platforms
Maintenance or replacement of one module doesn’t require dismantling the entire system
Transport is simplified—each skid fits standard shipping containers and transport vessels

The SLG450Q skid-mounted coiled tubing unit is purpose-built for ultra-deep wells and deep unconventional oil & gas development. Here's where it delivers the best return:
| Application | Description |
|---|---|
| Offshore Platforms | Space-constrained environments requiring crane-in/crane-out installation |
| Remote Onshore Locations | Areas without road access—fly-in, crane-in, operate |
| FPSO / FLNG Vessels | Marine applications requiring compact, liftable modules |
| Ultra-Deep Well Workovers | Interventions in wells beyond 5,000 meters requiring maximum pulling power |
| Deep Unconventional Oil & Gas Development | Shale gas, tight oil, and other deep unconventional resources |
| High-Sulfur / High-Corrosion Wells | Proven in Puguang Gas Field high-sulfur environments |
| Long Horizontal Well Interventions | Extended-reach laterals requiring substantial tubing length |
| Well Cleanout & Sand Flushing | Remove sand plugs and debris without killing the well |
| Acidizing & Stimulation | Precisely place acid across target zones |
| Nitrogen Lift & Gas Lift | Unload wells and kickstart production |
| Fishing & Milling Operations | Remove plugs, packers, or cement with automated drilling modes |
| Velocity String Installation | Run smaller-diameter tubing to address liquid loading |
| Configuration | Best For | Key Advantage |
|---|---|---|
| Standard Skid-Mounted (Modular) | Offshore platforms, remote onshore locations | Individual skids for each component; crane-in/crane-out simplicity |
| ATEX Zone II Skid-Mounted | Hazardous area operations | Explosion-proof components; certified for offshore and refinery environments |
| Combination Configurations | Operations needing mix of mobility and skid-mounted components | Truck or trailer for some modules, skids for others |
The modular "skid-in-skid” design means each functional component is on its own skid. This allows for flexible positioning around the wellhead, easier maintenance (one skid can be swapped without disturbing others), and transport optimization (each skid fits standard shipping dimensions).

🏭 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 don't just assemble—we engineer. Our SLG450 project was recognized as reaching international advanced level by Sinopec’s Science and Technology Department and received Sinopec Group's Science and Technology Progress Second Prize.
🎯 Automation Pioneer – "One-Key” Operation
We developed "一键式” operation ("one-key” operation) 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
SLG450 units have been deployed across China's major oilfields (Fuling, Weiyuan, Shengli, Puguang) and exported to Saudi Arabia, Africa, 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. In the Puguang Gas Field, SLG450 equipment successfully completed plug drilling operations at 6,121 meters, with cumulative operation mileage reaching 3.8 million meters.
📊 Field-Proven Performance – 3× Faster, 3.8 Million Meters
The SLG450 achieves 无节箍、不间断的连续起下作业 (no-collar, uninterrupted continuous pipe running and retrieval) with operating efficiency more than 3 times that of conventional equipment. Cumulative operation mileage has reached 3.8 million meters.
📋 Certified to International Standards
API Q1, ISO 9001, and HSE management system certified. Our manufacturing processes are audited annually.
🔄 One-Stop Service Commitment
Commissioning support, operator training, spare parts logistics, and technical troubleshooting—we stay with you after the sale. Our export team understands the logistics of international shipping and can arrange delivery to your location.
💰 Competitive Pricing, No Quality Compromise
Chinese manufacturing doesn't mean cutting corners. We deliver professional-grade coiled tubing equipment at prices that make sense for your capital budget—full transparency on materials, components, and workmanship.
Q1: What does the "Q” in SLG450Q stand for?
A: The "Q” stands for "橇” (skid) , indicating that this is a skid-mounted configuration. Unlike truck-mounted or trailer-mounted units, the SLG450Q consists of individual modules (injector, reel, power pack, control cabin) each mounted on its own skid, designed to be lifted by crane and placed on offshore platforms or remote onshore locations.
Q2: What's the pulling and snubbing capacity of the SLG450Q?
A: The SLG450Q 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 in ultra-deep wells.
Q3: What does "skid-in-skid” modular design mean?
A: "Skid-in-skid” refers to our modular approach where each major component is mounted on its own individual skid. This allows each module to be lifted separately (reducing crane capacity requirements), positioned independently around the wellhead, and maintained or replaced without dismantling the entire system.
Q4: Can the SLG450Q be used offshore?
A: Absolutely. Skid-mounted CTUs are the preferred configuration for offshore operations. The SLG450Q is available with ATEX Zone II explosion-proof certification for hazardous area operations.
Q5: What tubing sizes does the SLG450Q handle?
A: The unit handles tubing from 2″ up to 2-7/8″ as standard. Reel capacity is customized per your depth requirements.
Q6: What’s the operating temperature range?
A: The SLG450Q operates across a wide temperature range from −45°C to +55°C, making it suitable for polar, temperate, and desert environments. It has been field-proven in Saudi Arabia's extreme heat.
Q7: Does the SLG450Q support automation?
A: Yes. The SLG450Q supports "一键式”操作 ("one-key” automation) features including automatic pipe running and retrieval, automatic pipe spooling, and automatic lubrication—improving efficiency by 30%. The system also features three automatic drilling modes that reduce drilling time from 2–4 hours to 0.5–1 hour, a 50% efficiency improvement.
Q8: Has the SLG450Q been field-proven?
A: Yes. The SLG450 has been deployed across China's major oilfields and exported to Saudi Arabia and Africa. In the Puguang Gas Field, SLG450 equipment successfully completed plug drilling operations at 6,121 meters with cumulative operation mileage reaching 3.8 million meters. The SLG450 project has been recognized as reaching international advanced level.
Q9: What’s the typical lead time for an SLG450Q?
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 SLG450Q?
A: Send us your well parameters: target depth, tubing diameter, expected wellhead pressure, operating environment (offshore/onshore, temperature range), and any specific certification requirements (ATEX, etc.). We'll respond with a technical proposal and commercial quote within 7–10 business days.
