Product Series & Configurations

SJ Petroleum Machinery Co., Ltd. offers a family of helicopter portable drill rigs to meet different customer requirements. All models follow the same philosophy of modularity, transportability, and field‑proven reliability.

Model	Max Depth	Hook Load	Modules	Best Application
LS20H	4000 m (3‑1/2″ DP)	1470 kN	24 modules	Standard remote drilling, workover
2000m Heli Rig	2000–2500 m	1470 kN	22 modules	Shallow‑depth, fast mobilization
3000m Heli Rig	3000 m	Custom	Custom	Deep exploration, international export

The 3000m series was successfully developed and exported in 2006, following the proven success of our earlier 2000m models deployed internationally. Each model can be customized for top‑drive integration, mud pump upgrades, or region‑specific certification requirements.

Applications & Use Cases

[Insert Product Image 03: Helicopter lifting rig modules to site]

Engineered for versatility, our helicopter drilling rig has been successfully deployed across five continents in a wide range of extreme and logistically demanding environments:

Remote Mountain & Highland Exploration

When road construction is impossible due to steep grades, narrow valleys, or high passes, our heli‑rig modules are flown directly to mountain well locations. Proven in active operations throughout South America, New Guinea Highlands, and the Tibetan Plateau.

Swamp, Marsh & Wetland Operations

Wetlands and transition zones present unique challenges where conventional truck‑mounted rigs simply cannot go. The rig’s low ground pressure and air‑transportable modules protect sensitive wetland vegetation and water tables. Perfect for delta and coastal swamp exploration projects.

Offshore Development Drilling

In confined space offshore platforms, jack‑up decks, and floating facilities—where crane reach or deck weight capacity is limited—our modular rig can be lifted onto the deck piece by piece and assembled safely within tight footprints. Works seamlessly with platform utilities and mud handling systems.

Jungle & Rainforest Exploration

Minimal site clearing, no roads, and quick demobilization leave almost no permanent mark after operations are completed. The heli‑rig protects rainforest ecosystems while delivering the same drilling performance as conventional equipment.

Arctic & Permafrost Regions

Our rigs are field‑tested in Canada’s oil sands, where winter‑road restrictions limit conventional operations to only three to four months per year. With heli transport, you can achieve year‑round drilling access—equipment arrives when you need it, not when the ground finally freezes solid.

The rig has been supplied to international operators such as Loadmaster in Papua New Guinea, where it performed reliably across multiple well campaigns. Our units have also been exported to Australia, Africa, and throughout the Americas—a strong track record underscoring the reliability of our China-made oil drilling equipment in demanding global conditions.

Frequently Asked Questions (FAQ)

[Insert Product Image 04: Spare parts and maintenance area]

Q1: What type of helicopter is needed to move this rig?
The rig is designed for medium‑lift helicopters capable of carrying a 4‑metric‑ton sling load. Common aircraft used in previous projects include the MI‑26, S‑92, CH‑53, and similar models. Please consult our engineering team with your specific helicopter availability, and we will provide detailed module weight sheets, lifting diagrams, and balanced load plans.

Q2: How long does reassembly take at the drill site?
From the moment the last module arrives, an experienced crew of six to eight technicians can typically complete full assembly, rig‑up, and drilling readiness within 12–24 hours, depending on site conditions and crew familiarity.

Q3: Can the rig be operated without helicopter support after deployment?
Yes. Once assembled, the rig functions as a fully conventional drilling unit. It is not dependent on helicopters for daily operations—helicopters are only required for the mobilization and demobilization phases.

Q4: Is training included in the purchase?
Absolutely. We provide comprehensive on‑site assembly and drilling operations training for your crew, as well as detailed documentation, lifting plans, sling‑load center‑of‑gravity calculations, and full parts catalogs.

Q5: Does the rig comply with international safety and environmental standards?
Yes. The rig is designed and manufactured in alignment with ISO 9001 quality management standards, and meets or exceeds applicable API, ANSI, and OSHA safety requirements. OEM components from Caterpillar, Allison, and other global suppliers ensure international serviceability and parts availability. Certified documentation packages are available for your local regulatory and insurance requirements.

Q6: I need a deeper depth rating. Do you offer higher specifications?
Absolutely. Our engineering team has already developed 3000m class helicopter portable drilling rigs, and deeper or custom capacity designs can be quoted based on your specific drilling program requirements.

Q7: What is your typical lead time?
Standard manufacturing lead times range from 8 to 12 months depending on configurations and customization. Please contact our sales department with your desired delivery schedule, and we will provide a firm commitment.

Q8: Do you provide spare parts globally?
Yes. We maintain a global spare parts logistics system and can deliver common wear parts and critical components to most international airports within days of order confirmation. Emergency support requests are prioritized 24/7.
