| Skid-mounted CTU | Modular skid units, crane-transported | Offshore platforms, desert operations, permanent wellsite installations |
| Dual-Power CTU | Grid electric + diesel generator hybrid | High-utilization sites with grid access – lower energy cost and emissions |
| Quiet Diesel CTU | Diesel-driven with multi-layer acoustic insulation | Night operations, urban-adjacent drill sites, environmentally sensitive areas |
Why Choose SJ Petroleum Machinery as Your CTU Supplier?
1. Sinopec-Backed Manufacturing Power
We’re not a small workshop — we’re a Sinopec subsidiary with over 2,000 employees, a national‑level enterprise technology center, and over 200 national patents. Our 663,000 m² facility operates ISO 9001, API Q1, and HSE management systems. When you buy from us, you’re buying decades of state-owned enterprise engineering discipline.
2. Full API Certification & Global Compliance
Our CTUs are designed and manufactured to API standards — the international "passport” for oilfield equipment. This means your procurement team won’t face compliance hurdles, and your field supervisors can trust the equipment’s safety and interchangeability.
3. One-Stop Engineering Support
We don’t just ship a machine. Our team provides full on-site installation guidance, operator training, remote diagnostics, and spare parts logistics. We’ve supplied SLG270, SLG360, SLG450 series CTUs to Russia, South America, the Middle East, Africa, and Southeast Asia.
4. Factory-Direct Pricing Model
By eliminating middlemen and multi-tier distribution, we offer competitive CTU pricing without cutting corners on quality. For our fully electric SLG630, the price is roughly 20% lower than equivalent foreign models — with better after-sales response times for Asian and Middle Eastern clients.
5. Proven Field Performance
In 2024, our SLG450 CTU logged over 2,800 hours of operation, completed 120+ well interventions, and accumulated over 3 million meters of coiled tubing run — with maximum operating depth reaching 4,965 meters. Operational efficiency exceeded the same period benchmark by 20%. That’s not marketing hype; that’s field-verified data.
FAQ – Coiled Tubing Unit Pricing & Selection
Q1: What factors affect coiled tubing unit price?
Several variables directly impact CTU pricing: lifting capacity (50kN to 900kN), tubing diameter compatibility (3/8″ to 4.5″), power configuration (diesel, grid electric, or hybrid), mobility type (truck, trailer, or skid-mount), level of automation (manual vs one-key auto), and optional features like remote monitoring or dual-power systems. In general, larger capacity and higher automation command higher initial cost but significantly lower long-term operational expenditure.
Q2: How does your pricing compare to European or North American suppliers?
For comparable technical specifications, our CTUs are typically 15–25% lower in initial purchase price than equivalent Western brands. More importantly, our factory-direct support and proximity to major oil regions (Middle East, SE Asia, Africa) mean shorter lead times and lower spare parts shipping costs.
Q3: What is the typical lead time for a coiled tubing unit?
Standard configurations: 90–150 days from order confirmation to delivery. Custom-engineered units with non-standard specifications: 150–180 days, depending on complexity and production schedule.
Q4: Do you provide OEM or custom design services?
Absolutely. We offer full OEM services for clients who require specific modifications — customized reel capacities, specialized injector designs, climate adaptations (arctic or high-temperature packages), and unique control system integrations.
Q5: What after-sales support do you offer?
Remote diagnostics via our data transmission platform, field technician dispatch for major commissioning, 24/7 technical hotline, and a comprehensive spare parts inventory with global shipping capability.
Q6: Can your CTUs operate in offshore environments?
Yes. Our skid-mounted CTU series is specifically designed for offshore platforms — corrosion-resistant materials, modular crane-liftable components, and compact footprint to maximize limited deck space.
Q7: What’s the difference between SLG270, SLG450, and SLG630?
SLG270 is our truck-mounted "one-truck” solution for mature oilfields requiring rapid, small-scale repairs. SLG450 is our mid-range workhorse — available in truck, trailer, or skid configuration — suitable for most conventional well interventions. SLG630 is our heavy-duty electric-driven unit designed for deep shale gas and large-tonnage operations. Choose based on your average well depth and required lifting capacity.
Q8: What certifications do your CTUs carry?
API Q1 (Quality Management System), ISO 9001, ISO 14001, OHSAS 18001/HSE. Product-level API monogram certification available upon request for specific components and complete units.
Q9: How do I request a coiled tubing unit price quote for my specific well conditions?
Contact our sales team through the form below or email us directly. Please provide: target well depth, required lifting capacity (kN or tons), preferred tubing diameter, mobility requirement (truck/trailer/skid), power preference (diesel/electric/hybrid), and any special environmental conditions (offshore, arctic, H₂S service, etc.). We’ll provide a detailed price proposal within 48 hours.
Q10: Do you ship worldwide? How are CTUs packaged for international transport?
Yes — we’ve exported to Russia, South America, the Middle East, Africa, and Southeast Asia. Our logistics team uses heavy-duty export crating, anti-corrosion treatment, and full container or break-bulk vessel loading depending on unit size. All export documentation, customs clearance support, and inland transport coordination are included in our global delivery service.
