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. Since 2004, we have been developing coiled tubing equipment and have formed a complete integrated solution capability.

🔧 Full-Spectrum Engineering Capability

From injector head to control cabin, we design and build major components in-house. Core components are over 90% domestically produced. We’ve mastered heavy-load injector heads, large-capacity quick-change reels, automated control systems, and integrated modular designs. We don't just assemble—we engineer.

🌍 Proven in the Field – 80+ Jobs and Counting

The SLG360 has completed over 80 well intervention jobs since its introduction, with a maximum operational depth of 6,500 meters, wellhead pressures up to 45 MPa, and circulation pressures reaching 60 MPa. It has been deployed in polar, marine, and desert environments and has proven itself in high-sulfur, high-corrosion conditions.

❄️ Extreme Condition Certified

The SLG360 has been successfully applied in −45°C low-temperature operations, 8,000-meter deep wells, and continuous long-duration jobs. If your operating environment is harsh, we've already tested the SLG360 in conditions as tough or tougher.

📋 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.

Frequently Asked Questions (FAQ)

Q1: What's the actual pulling and snubbing capacity of the SLG360?

A: The SLG360 delivers 360 kN (80,000 lbs) of continuous pulling force and 180 kN (40,000 lbs) of continuous snubbing force. These are continuous ratings, not peak—you can rely on these numbers for sustained operations.

Q2: What’s the maximum working pressure?

A: The SLG360 is rated for a maximum working pressure of 103.5 MPa (15,000 psi) . Field operations have demonstrated wellhead pressures up to 45 MPa and circulation pressures up to 60 MPa.

Q3: What tubing sizes and depths does the SLG360 handle?

A: The standard configuration handles 2″ tubing to 5,000 meters. Field operations have demonstrated maximum depths of 6,500 meters. Reel capacity and tubing diameter are customizable per your requirements.

Q4: What’s the integrated single-unit configuration?

A: The integrated configuration consolidates the injector head, tubing reel, control cabin, and power system onto a single chassis. It eliminates one support vehicle and one power system compared to traditional configurations, reduces equipment footprint by 30 square meters, and cuts installation time by over 3 hours. It's the most highly integrated coiled tubing unit developed in China.

Q5: Can the SLG360 operate in extreme cold?

A: Yes. The SLG360 has been successfully applied in −45°C low-temperature operations. Cold-weather packages are available.

Q6: What mounting options are available?

A: Truck-mounted, trailer-mounted, skid-mounted, integrated single-unit, and combination configurations. Tell us how you plan to move the unit and where it will operate, and we'll recommend the best option.

Q7: Has the SLG360 been proven in the field?

A: Yes. The SLG360 has completed over 80 well intervention jobs since its introduction, including high-sulfur, high-corrosion environments in the Puguang Gas Field. It has been deployed in polar, marine, and desert environments.

Q8: What’s the typical lead time?

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.

Q9: Do you provide training and after-sales support?

A: Absolutely. Each SLG360 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 SLG360?

A: Send us your well parameters: target depth, tubing diameter, expected wellhead pressure, preferred mounting configuration, and operating environment. We'll respond with a technical proposal and commercial quote within 7–10 business days.
