Product Types – Heavy‑Duty Equipment Family
We classify heavy‑duty drilling equipment into four tiers based on depth and hook load:
| Tier | Depth (m) | Hook Load (lbs) | Drawworks (HP) | Typical Application |
|---|---|---|---|---|
| SJ‑HD‑7000 | 7,000 | 700,000 | 2,000 | Deep HPHT onshore |
| SJ‑HD‑8000 | 8,000 | 850,000 | 2,500 | Ultra‑deep onshore / deepwater |
| SJ‑HD‑9000 | 9,000 | 1,000,000 | 3,000 | Extreme depth, large casing |
| SJ‑HD‑10000 | 10,000+ | 1,250,000 | 4,000 | Record wells, scientific drilling |
Each tier is available in skid‑mounted (land), offshore platform, or drillship configurations. All include arctic, desert, or high‑altitude packages as required.
Retrofit kits – Upgrade existing rigs to heavy‑duty standards (new drawworks, top drive, BOP, control system).
Why Choose SJ Petro for Heavy‑Duty Drilling Equipment?
1. Proven Ultra‑Deep Experience – We have supplied heavy‑duty rigs for wells exceeding 8,500 meters in China, Middle East, and South America. Our equipment has drilled some of the world’s deepest onshore wells.
2. API 4F, 7K, 8C, 16A Certified – Not "designed to API” – fully certified with monograms. Third‑party witness testing available.
3. In‑House Engineering for Extreme Loads – We do not just scale up standard designs. Our engineering team performs FEA (finite element analysis) on every mast and substructure to validate dynamic load capacities.
4. Redundancy Built In – Twin mud pumps, dual drawworks drive systems, multiple BOP control accumulators. The rig does not stop for a single component failure.
5. Extreme Environment Validation – We test our arctic packages at -50°C in our climate chamber. Desert packages are validated at 55°C in field tests. Not theoretical – proven.
6. Global Service & Spares – Heavy‑duty components (drawworks drums, top drive heads, BOP rams) stocked in Houston, Dubai, and Singapore. 24/7 support.
7. Short Lead Times for Heavy‑Duty Rigs – 14‑18 months for a 9,000m rig (vs 20‑24 months from many competitors). Standardization of components across tiers reduces engineering time.
8. Sinopec Financial Strength – As a Sinopec subsidiary, we have the resources to support long‑term heavy‑duty drilling campaigns, including lease and financing options.
Frequently Asked Questions (FAQ)
Q1: What is the highest hook load rig you have manufactured?
We have delivered a rig rated for 1,250,000 lbs (5,560 kN) static hook load. It is currently drilling in Central Asia.
Q2: Can your heavy‑duty rigs handle 20,000 psi well pressure?
Yes – with our API 16A 20,000 psi BOP stack, 20,000 psi choke manifold, and high‑pressure mud pumps (up to 10,000 psi circulating pressure). The rig itself is rated for the associated loads.
Q3: Do you offer dual drawworks for extra redundancy?
Yes – for extreme wells we can configure a rig with two independent drawworks that can be clutched together for high load or run separately for redundancy.
Q4: What is the maximum depth your heavy‑duty rigs can drill?
With 5‑1/2″ drill pipe and optimized mud systems, our SJ‑HD‑10000 is rated for 10,000+ meters (33,000+ ft). Actual depth depends on casing program and formation pressures.
Q5: How do you transport a heavy‑duty rig of this size?
Our rigs are modular. The 9,000m class breaks into 85‑100 modules, each under 30 tonnes. They ship in standard 40‑ft containers or on flat racks. On site, a 250‑ton crane is typically required for the heaviest modules (substructure beams).
Q6: What is the typical fuel consumption of a heavy‑duty rig?
A 3,000 HP rig at full load consumes approximately 100‑150 gallons per hour (380‑570 L/h). At idle or light drilling, consumption drops to 20‑30 GPH.
Q7: Can the rig be automated (auto‑driller, auto‑connection)?
Yes – our heavy‑duty rigs are fully automatable. We offer Level 2 to Level 4 automation (remote control, auto‑driller, auto‑tripping, remote cabin).
Q8: Do you provide training for operating heavy‑duty drilling equipment?
Yes – 4‑6 weeks of training including classroom, simulator, and on‑site supervision for the first well. Heavy‑duty specific topics: high‑load handling, deep well hydraulics, HPHT BOP drills.
Q9: What is the warranty on heavy‑duty drilling equipment?
18 months from shipment or 12 months from commissioning (whichever first). Extended warranty (up to 5 years) available for major components (drawworks, top drive, BOPs).
Q10: Can you supply a heavy‑duty rig on a lease or rental basis?
Yes – we have heavy‑duty rigs available for long‑term lease (1‑5 years). Minimum commitment $5M USD per year. Shorter rentals are possible for specific deep well projects – contact us.
Q11: What are the biggest challenges in designing ultra‑deep rigs?
Three areas: (1) managing mast deflection under high dynamic loads; (2) cooling high‑power motors and electronics in tight spaces; (3) maintaining reliable BOP function at 20,000 psi for extended periods.
Q12: How do I get a quote for a heavy‑duty drilling rig?
Provide: planned total depth, casing program (sizes and setting depths), expected formation pressure and temperature, desired hook load, and environment (arctic/desert/offshore). We will respond with a technical proposal and fixed price within 10‑15 business days.
