Applications – Where Our Modular Rigs Excel
Multi‑well pad drilling (unconventionals, tight gas, shale)
Standardized skidding systems move the rig between slots in hours. Our BE series modular rigs have drilled multi‑well pads in West Texas and the Middle East with documented per‑well move times under 24 hours.
Desert field development (Middle East / North Africa)
Saudi Arabia, Kuwait, Algeria, Niger. Our desert modular rigs operate at 55°C with forced cooling and sand‑sealed components. ZJ90DB desert modular rigs achieved full mast rise in Kuwait’s northern oilfield in 2025 – a benchmark for Chinese‑made modular equipment in the high‑end Middle Eastern market.
Remote jungle and mountain basins (South America, SE Asia)
Heli‑transportable modular rigs are the only practical solution for roadless locations. Our rigs have operated in the Amazon basin and Papua New Guinea – delivered by helicopter, assembled on site, and drilled successfully.
Offshore fixed platforms
ISO‑standardized modules fit platform crane limits and deck space. Complete drilling and workover packages, pre‑assembled and tested onshore to minimize expensive offshore installation days.
Arctic exploration (Siberia, Northern Canada, Alaska)
GOST‑certified modular rigs rated for –45°C continuous operation. Special steel grades, heated enclosures, and low‑temperature hydraulic fluids. 102 rigs delivered to Russia – many of them arctic modular configurations.
International greenfield projects
When you’re bringing a rig into a new country, modular design simplifies everything: containerized shipping, straightforward customs classification, simple local assembly without specialist tools or extensive supervision.

Why Choose SJ Petroleum Machinery as Your Modular Drilling Rig Manufacturer?
We are a manufacturer, not a trading company. Some suppliers buy components, assemble them, and call themselves manufacturers. We don’t. We pour steel, fabricate masts, machine drawworks, wind motors, and test every system in‑house. That means we control quality, cost, and delivery.
We have the scale to deliver. 250 rigs per year capacity. 17 production lines. 2,000+ employees. When you place an order, it goes into a real production schedule – not a wish list.
We carry the certifications that matter. API 4F, 7K, 8C with monogram. ISO9001. HSE. GOST. CE. Third‑party audits are routine. You can verify every cert.
We have global field experience. 297 overseas rig deliveries. North & South America, Russia, Middle East, North Africa, Southeast Asia. We understand export logistics, local certification requirements, and the importance of on‑site support.
We are backed by Sinopec. Our parent company is one of the world’s largest energy equipment conglomerates. Financial stability. Supply chain strength. Long‑term commitment to the industry.
We provide full lifecycle support. Not just a warranty card. On‑site commissioning, crew training, global spare parts inventory (48‑hour critical parts shipment), field service engineers, and overhaul/refurbishment services.
Our pricing is competitive. Same API certifications as Western manufacturers. Lower manufacturing cost base. Transparent quotations with line‑by‑line breakdown. No hidden "regional surcharges.”
Frequently Asked Questions (FAQ) for Modular Drilling Rig Manufacturers
Q1: How do I verify that you are a real manufacturer, not a trading company?
A: Several ways: (1) Request a factory audit – we welcome customer inspections at any time. (2) Check our API monogram license – API audits our manufacturing facilities annually. (3) Review our export records – 297 overseas rig shipments directly from our factory. (4) Ask for reference visits to our 663,000㎡ campus. We’re easy to verify.
Q2: What is your typical lead time for a modular drilling rig?
A: 6–9 months for standard modular configurations (BE series, super single‑joint). 9–12 months for custom deep or ultra‑deep modular rigs. 12–18 months for heli‑transportable, arctic, or offshore modular rigs. Rush delivery possible depending on current production load.
Q3: Do you manufacture all major components in‑house?
A: Masts, substructures, drawworks, mud pumps, top drives, and pressure vessels are manufactured on our own lines. Engines, generators, and some electronic components are sourced from reputable global brands (Caterpillar, Cummins, Siemens, etc.) to customer preference. You can specify your preferred brand for third‑party components.
Q4: Can you customize a modular rig for my specific well plan?
A: Yes – custom engineering is our standard process. We don’t force you into a pre‑set configuration. Provide your target depth, well count and spacing, terrain, climate, and power preference. Our engineers will design a modular rig to fit your exact requirements.
Q5: What is the minimum order quantity for a custom modular rig?
A: One. We design and build single rigs for specific projects. You don’t need to order a fleet to get our engineering attention.
Q6: Do you provide on‑site assembly and training?
A: Yes. Our field service engineers travel with each major modular rig shipment to oversee assembly, interconnection, commissioning, and initial drilling. We also provide comprehensive training for your crews – either at our factory or on location.
Q7: How do you handle spare parts?
A: We maintain a global spare parts inventory. Critical components can be shipped within 48–72 hours to most international locations. For fleet operators, we offer consignment inventory programs and scheduled parts replenishment.
Q8: What quality control processes do you have?
A: We operate under API Q1 quality management. Every major component undergoes dimensional inspection, material testing, non‑destructive examination (NDE), and functional testing. Our seven laboratories include facilities for chemical analysis, mechanical testing, and pressure testing. Final module assembly is fully tested before disassembly for shipping.
Q9: Can I send my own inspector to your factory during production?
A: Absolutely. Third‑party inspections from BV, DNV, ABS, or your own designated agency are welcome at every stage – raw material receiving, in‑process fabrication, final assembly, and load testing.
Q10: How do I get a quotation for a modular drilling rig?
A: Contact our international sales team with your project parameters: target drilling depth, number of wells (and spacing), terrain description, ambient temperature range, preferred power system, and any required certifications. We will respond within 48 hours with an initial technical assessment and quotation timeline.
