Applications – Where the SLG270 One-Truck Excels
The SLG270 is designed for efficient, low-cost workover operations in mature oilfields. Here's where it delivers the best return:
|
Application
|
Description
|
|
Routine Well Workovers

One job per day, day after day—the SLG270 is built for this rhythm
|
|
Sand Flushing & Well Cleaning
|
Remove sand plugs and debris without killing the well
|
|
Paraffin & Scale Removal
|
Clear wax buildup and mineral scale to restore production
|
|
Acidizing
|
Precisely place acid across target zones for stimulation
|
|
Nitrogen Lift & Gas Lift
|
Unload wells and kickstart production

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 2005, we have successively developed the SLG270, SLG360, and SLG450 series coiled tubing units, forming industrial-scale production of truck-mounted, skid-mounted, and trailer-mounted configurations.
🌍 Proven Global Track Record
SLG270 and other SLG series coiled tubing units are actively working across China's major oilfields and have been exported to Russia, South America, the Middle East, Africa, and Southeast Asia.
❄️ Field-Proven in Extreme Conditions
The SLG270 has been deployed and proven in −45°C低温环境 (extreme low temperatures). If your winter campaign demands cold-weather performance, we've built units that deliver it.
📋 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 makes the SLG270 "single-truck” different from a standard truck-mounted CTU?
A: Most "truck-mounted” CTUs actually require a separate reel trailer or power pack trailer—they're really two- or three-vehicle systems. The SLG270 is true single-truck: injector head, tubing reel, crane, power pack, and control cabin are all on one chassis. No trailers. No second vehicles. One truck does it all.
Q2: What’s the pulling and snubbing capacity?
A: Maximum pulling force is 270 kN (60,000 lbs) and maximum snubbing force is 135 kN (30,000 lbs) . These are continuous ratings suitable for sustained operations.
Q3: What tubing sizes and capacities does it handle?
A: The standard configuration handles 1.5″ tubing to 3,500 meters. We can customize reel capacity for other tubing diameters—contact our engineering team with your specific depth requirements.
Q4: Can the SLG270 operate in extreme cold?
A: Yes. The unit has been specifically engineered and tested for −45°C低温环境 (extreme low-temperature operation). The cold-weather package includes engine block heaters, heated hydraulic reservoirs, insulated lines, and low-temperature seals.
Q5: How fast can we rig up and start working?
A: The integrated single-truck design reduces rig-up time by 50% compared to traditional multi-trailer configurations. From arrival to first pipe movement, figure significantly less time than you're used to with conventional CTU setups.
Q6: How many people does it take to run the SLG270?
A: The integrated control system allows operation with just 2 to 3 people. This reduces labor costs and simplifies crew logistics.
Q7: What’s the typical lead time?
A: Standard lead time is 90 to 120 days from order confirmation to shipment, depending on configuration and customization level. Contact our sales team for current availability.
Q8: Do you provide training and after-sales support?
A: Absolutely. Each SLG270 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.
Q9: How do I get a quote for an SLG270?
A: Send us your well parameters: target depth, tubing diameter, expected wellhead pressure, operating environment (especially if you need the cold-weather package), and any specific customization requirements. We'll respond with a technical proposal and commercial quote within 7–10 business days.
