Product Types — Which Configuration Fits Your Operation?

SJ offers several distinct configurations of truck-mounted drilling rigs for sale, so you can match the machine to your specific operational requirements rather than accepting a one-size-fits-all compromise.

1 ZJ Series Truck-Mounted Drilling Rigs (Pure Drilling Focus)

The ZJ series is our flagship line for mobile drilling applications. These rigs are configured primarily for new well drilling in shallow to medium-depth reservoirs, with depth capabilities from 1,000 meters (ZJ10) up to 4,000 meters (ZJ40). They are designed for rapid relocation between well pads, infill drilling programs, and remote exploration campaigns where moving a conventional trailer-mounted rig would be logistically impractical.

2 XJ Series Dual-Purpose Drilling & Workover Rigs

For operators who need both drilling and well service capability, the XJ series offers the best of both worlds. The XJ750, for example, is a 1,700 kN hook load rig powered by dual Caterpillar C15 engines and Allison M5610HR transmissions, capable of drilling new wells up to 3,000 meters while also handling workover operations up to 8,000 meters. This dual-purpose design eliminates the need to maintain separate fleets for drilling and well service, dramatically reducing capital and operating costs.

3 Climate-Specialized Configurations

Cold-Weather Package (Arctic / Siberian Grade): Designed for operation down to -45°C and storage down to -60°C, featuring cold-weather materials, heat preservation processes, low-temperature lubricants, and heated operator enclosures. These specifications are field-proven on ZJ40 rigs exported to Russia’s Orenburg region, where they operate through harsh Siberian winters.

Desert Package (Middle East / Sahara Grade): Enhanced cooling systems, sand and dust filtration, wide-track or desert tire configurations, and reinforced sealing against fine particulate intrusion. These rigs are engineered for continuous operation in +50°C ambient temperatures with high dust loads, based on proven performance in Kuwait and other Middle Eastern markets.

4 Custom Carrier Configurations

Standard models use specific drive configurations (8×6, 10×8, 12×8, 14×8, 14×10), but SJ can also customize axle configurations, tire specifications, and chassis reinforcements based on your specific terrain conditions and road transport regulations.

Applications

Our truck-mounted drilling rigs have been deployed across six continents in a wide range of operational scenarios. Here’s where they’ve proven themselves most valuable.

• Shallow-to-Medium Depth Oil & Gas Drilling – The core application for our ZJ series. Infill drilling programs, development wells in mature fields, and exploration wells in remote areas all benefit from the self-mobilizing capability and rapid rig-up time of truck-mounted designs.

• Well Workover and Intervention – When an existing well needs maintenance, pulling and running tubing, fishing jobs, milling obstructions, or recompletion work, our XJ series dual-purpose rigs deliver heavy-duty well service capability with the mobility to jump between wells in the same pad.

• Water Well Drilling – Rural and agricultural water supply projects. The self-contained design eliminates the need for support vehicles on small to medium-diameter water wells, making these rigs exceptionally cost-effective for water well contractors.

• Geothermal Exploration & Development – With depth capabilities up to 4,000 meters and reliable mud circulation systems, our rigs are well-suited for geothermal gradient drilling and production well installation in volcanic and tectonic regions.

• Remote & Infrastructure-Limited Locations – When the last paved road was 200 kilometers behind you, a truck-mounted drilling rig that can drive itself onto location becomes not just convenient but essential. Our rigs have drilled in jungle environments, mountain regions, and desert outposts where bringing in a conventional rig would require building an entire access road.

• Extreme Climates – As noted above, SJ has delivered operational rigs in both Arctic (Russia) and desert (Kuwait, Middle East) environments. Our climate packages are not theoretical — they’re based on actual field operating data from real projects.

• Corporate Well Service Fleets – For national oil companies and large independent operators running centralized well service fleets, having standardized, self-mobilizing truck-mounted drilling and workover rigs dramatically simplifies fleet management, parts stocking, and crew training.

Why Choose SJ Petroleum When You’re Looking for a Truck-Mounted Drilling Rig for Sale?

If you’re reading this, you’ve probably looked at multiple suppliers. You’ve seen the glossy brochures, the generic specifications, and the too-good-to-be-true pricing from manufacturers you’ve never heard of. Here’s why SJ Petroleum is different.

✅ Backed by Sinopec Group – We’re not a garage operation or a middleman. SJ Petroleum is a wholly-owned subsidiary of Sinopec Oilfield Equipment Corporation, which itself is part of Sinopec Group — one of the world’s largest integrated energy companies, consistently ranked in the Fortune Global 500. That means we have the financial stability, the technical resources, and the supply chain depth that smaller manufacturers simply can’t match.

✅ Eight Decades of Manufacturing Heritage – Founded in Lanzhou in 1941, relocated to Jingzhou in 1969 to support the Jianghan Oilfield Battle, renamed the Fourth Machinery Factory, and eventually restructured into the independent legal entity you’re dealing with today. That’s not a marketing story — that’s actual manufacturing history. We’ve been building heavy machinery continuously for over 80 years. When we say we know how to build a rig, we have the oldest machines in the field to prove it.

✅ Over 200 National Patents and a State-Recognized Technology Center – SJ has been recognized as a "national enterprise technology center,” a "national manufacturing single championship demonstration enterprise,” and has won second prize in the National Science and Technology Progress Award. Our technical center employs 314 dedicated R&D personnel — not designers who learned oilfield equipment last week, but engineers who have built their entire careers around drilling and workover equipment.

✅ True End-to-End Manufacturing Capability – We don’t just assemble components from third parties. SJ owns seven dedicated production lines for drawworks, gear boxes, cylinders, masts, high-pressure manifolds, plunger pumps, and post-treatment processes, along with three assembly lines for drilling rigs, workover rigs, and cementing and fracturing equipment. Our rig assembly yard spans 50,000 square meters with 24 rigging-up positions and two offshore rig commissioning sites that can test up to 750 tons and assemble up to 12 drilling or workover rigs simultaneously. That’s a lot of numbers, but here’s what they mean for you: shorter lead times, better quality control, and complete supply chain visibility from raw material to delivered rig.

✅ Globally Recognized Certifications – We hold API monogram licenses for Spec 4F (drilling and well servicing structures), 7K (drilling equipment), and 8C (derricks), plus API Q1, ISO 9001, and HSE management system certifications. Whether your project is in North America, Europe, Africa, the Middle East, or Asia, SJ rigs meet the certification requirements you’re going to need.

✅ Proven Export Track Record – We’ve shipped truck-mounted drilling rigs to Russia (including the Orenburg region’s ZJ40 cold-weather rigs), Kuwait, multiple countries across the Middle East, Southeast Asia, West Africa, and North America. We’re not new to international shipping, customs clearance, or export compliance — we’ve been doing it for decades.

✅ Engineering That Actually Sees the Field — You can’t design a good rig from an air-conditioned office. SJ engineers work with our customers in the field — sometimes living on location, as our team has done with Russian operators, establishing an on-site presence to conduct joint market research, product selection, and design optimization. We don’t guess what you need. We stand next to you and figure it out together.

✅ Genuine Customization — We don’t make you choose from three preset "packages” that almost fit your needs. Need a specific drivetrain configuration? Done. Want to swap components to meet local content regulations? We’ve done that. Running a project in a country with unique road transport laws? We’ll engineer the axle configuration and weight distribution to comply.

✅ Competitive Pricing Without Cutting Corners — This is the part where most manufacturers get vague. We won’t pretend we’re the cheapest rig on the market — because the cheapest rigs break, and a broken rig doesn’t drill. But because we’re a Sinopec subsidiary with an integrated, in-house supply chain, we don’t pay third-party markups on components, shipping, or assembly. You pay for the rig you get, not for a chain of middlemen.

✅ 100 Drilling Rigs per Year Production Capacity — That’s our current annual output capacity: 100 drilling rigs (including truck-mounted and trailer-mounted units), 100 workover rigs, 120 cementing units, 80 fracturing units, and over 700 pumps per year. That’s not hypothetical capacity — that’s what we actually produce. So when you place an order, you’re not waiting for us to figure out how to build your rig. You’re simply moving into the next available slot in an already-running production line.

Frequently Asked Questions (FAQ)

Q1: What’s the typical lead time if I order a truck-mounted drilling rig for sale today?

Standard delivery for a ZJ series rig (e.g., ZJ30 or ZJ40) is approximately 8 to 12 months from order confirmation, depending on model and customization requirements. SJ maintains a dedicated production line for these rigs, so lead times are generally predictable and consistent. For urgent projects, expedited delivery may be available — please contact our sales team to discuss your specific timeline.

Q2: What’s included in the purchase price?

All SJ truck-mounted drilling rigs include the integrated rig package (carrier chassis, mast, drawworks, power system, transmission, driller’s cabin, and basic hydraulics), API documentation and certification, factory acceptance testing (witnessed at our facility in Jingzhou), and export packaging. Additional services — on-site commissioning, operator training, spare parts kits, and extended warranties — are available as separate line items. We recommend requesting a comprehensive quotation that clearly itemizes all inclusions.

Q3: Do you offer financing or leasing options?

As a wholly-owned subsidiary of Sinopec, SJ works with international financial institutions and can facilitate various payment structures depending on the buyer’s jurisdiction and credit standing. These typically include letters of credit (L/C), T/T, and milestone-based payment schedules. For leasing inquiries, we can refer you to specialized oilfield equipment leasing partners. Please reach out to our commercial team with your specific requirements.

Q4: How are the rigs shipped internationally?

SJ has extensive experience in international shipping. The rig is broken down into its major transport modules, packaged according to your destination’s customs and shipping requirements, and transported either by container vessel or roll-on/roll-off (Ro-Ro) shipping. We coordinate all export documentation, customs declarations, and port logistics. For example, our ZJ40 shipments to Russia’s Orenburg region were delivered under DDP (Delivered Duty Paid) terms, with all formalities and charges completed by SJ, giving our customer a completely hands-off delivery experience.

Q5: What support do you provide after the rig is delivered?

Every rig purchase includes:

• Comprehensive technical documentation (operation manuals, parts lists, maintenance schedules, electrical and hydraulic schematics)

• Remote technical support via email, phone, and video

• On-site commissioning services (available upon request for additional fee)

• On-site or off-site operator and maintenance training (available upon request)

• Access to our global spare parts network for wear parts and critical components

For large fleet purchases, SJ can assign dedicated field service personnel to your operation for extended periods.

Q6: What payment methods do you accept?

Standard payment terms are typically structured around a combination of advance payment, milestone payments (typically upon completion of major manufacturing stages), and final payment upon factory acceptance testing and shipping. Specific payment methods include wire transfers (T/T), letters of credit (L/C) confirmed by major international banks, and other mutually agreed structures. All financial arrangements are subject to negotiation and compliance with applicable international trade regulations.

Q7: Do your rigs require a crane for mast erection or rig-up?

No. One of the key design features of SJ truck-mounted drilling rigs is the integrated hydraulic mast erecting system. The two-section telescoping mast is raised and extended entirely through hydraulic cylinders built into the rig structure. You do not need to rent or mobilize a separate crane for mast operations, which eliminates equipment rental costs, reduces on-site personnel exposure, and cuts rig-up time significantly.

Q8: How long does it take to rig up and start drilling once the rig arrives on site?

For a standard ZJ series truck-mounted rig on a prepared wellsite with an experienced crew, rig-up from arrival to spud typically takes 24 to 48 hours. The exact time depends on site conditions, crew familiarity with the equipment, and whether the rig is being moved from a previous well (rig-down time) or arriving fresh from transport. The hydraulic mast erecting system and pre-wired, pre-piped modules significantly reduce on-site assembly time compared to conventional rig designs.

Q9: What’s the maintenance schedule look like?

SJ provides comprehensive maintenance documentation with every rig. Typical intervals include:

• Daily checks: Fluids, hydraulics, brakes, tires, mast lock pins, wireline condition

• Weekly/50-hour service: Grease fittings, air system checks, fastener torque verification

• Monthly/250-hour service: Engine and transmission oil and filter changes (dependent on operating conditions)

• Annual/2,000-hour service: Full system inspection, brake system overhaul, mast and substructure structural inspection

Maintenance-intensive components like the Allison transmission and Caterpillar engines have service parts available globally through Allison and Caterpillar’s authorized dealer networks.

Q10: Can SJ provide custom rig configurations beyond the standard ZJ series options?

Absolutely. SJ has a full in-house engineering team and manufacturing capability to produce fully custom drilling and workover rigs. We’ve built rigs with single-engine, dual-engine, electric, and dual-power configurations; rigs with specialized climate packages for Arctic and desert environments; rigs with custom axle configurations to meet local road transport regulations; and rigs with integrated automation and top-drive systems. If you need something that isn’t in the standard brochure, we can design and build it.

Q11: How does SJ compare to other truck-mounted drilling rig manufacturers like BOMCO, RG Petro, or international manufacturers?

Here’s the honest comparison.

SJ is not the largest manufacturer in China — BOMCO holds that distinction. But SJ has three specific advantages that matter to many buyers. First, our specialization in mobile rigs (truck-mounted and trailer-mounted designs) means we’ve refined these specific products over decades, while larger manufacturers sometimes treat mobile rigs as a secondary product line. Second, as a Sinopec subsidiary, SJ offers the financial stability and compliance assurance that smaller or independent manufacturers cannot provide. Third, our pricing is generally more competitive than international manufacturers (National Oilwell Varco, etc.) while our quality meets the same API certification standards — because we build with Caterpillar/Allison components, just like they do.

If price is your only consideration, there are cheaper options out there. If you want a rig that works, has proper certifications, will be supported after the sale, and comes from a company with a real track record, SJ is the smart choice.

Q12: Do you have references I can talk to from customers using SJ truck-mounted rigs in my region?

Yes. SJ can provide references from customers in Russia (Orenburg region), the Middle East (Kuwait), and other international operating regions upon request, subject to customer privacy agreements. We recommend discussing your specific operating region with our sales team so we can direct you to the most relevant reference customers.
