Application Fields

1. Onshore Conventional Well Drilling (3,000–5,000m)

The most common deployment for our AC VFD land rigs. Rig automation reduces crew exposure, improves tripping speeds, and lowers energy costs. For multi‑well pad operations, automated systems pay back quickly — hundreds of connections per well, dozens of wells per pad.

2. Deep & Ultra‑Deep Well Drilling (6,000–9,000m)

SJ has manufactured and deployed 6 units of 9,000-meter deep well VFD drilling rigs for Kuwait National Petroleum Company [4†L26-L29]. These rigs feature automated equipment controls, positive pressure explosion-proof driller’s cabins integrated with side rooms, VFD power, modular design, good structural stability, and combined advantages of integral skidding and quick assembly/disassembly to handle frequent relocation needs in Kuwait’s desert oil fields [4†L36-L38]. A dedicated technical service team of dozens accompanies the equipment, providing "installation and commissioning — operator training — after‑sales maintenance” one‑stop service.

3. Shale Gas & Unconventional Resource Drilling

Multi‑well pad operations require hundreds of connections per well. Automated pipe handling reduces connection time by 20‑30 seconds per stand. Sinopec’s Idrilling system has been applied in nearly 400 wells across deep and ultra-deep formations, shale gas, tight gas, and other unconventional reservoirs — achieving an average ROP increase of 19.34% and average drilling cycle reduction of 12.93% while significantly reducing complex failure rates.

4. Offshore Drilling Platforms

Space constraints and stringent safety requirements make automation particularly valuable offshore. Our offshore automated drilling rig systems are equipped with dual driller ring network integrated control systems and automatic horizontal catwalks — enabling unified centralized management of rig parameters and controls with minimal personnel on board [14†L5-L10].

5. Workover & Well Intervention

Our automated workover rigs (XJ150 through XJ1200 series, maximum static load ranging from 300 to 2,250 kN) incorporate automated catwalks and automated lifting/lowering of drill pipes — enabling "one‑click” activation of automatic drill feeding and shackle loading .

6. Desert & Harsh Environment Drilling

Our 9,000-meter rigs deployed in Kuwait have proven performance in desert conditions — high ambient temperatures, sandstorms, and frequent relocation needs. The modular design and VFD power systems perform reliably under extreme conditions.

FAQ – Latest Drilling Technology

Q1: What actually defines "latest drilling technology” in 2026?

It’s not any single technology — it’s the integration of three core capabilities: (1) AC frequency conversion drives for energy efficiency (30‑40% savings), (2) automated pipe handling systems (catwalk, manipulator, iron roughneck, monkey board) removing crews from the red zone, and (3) AI‑driven intelligent control systems that optimize drilling parameters in real time. When these work together through a unified control platform, you achieve true autonomous or semi‑autonomous drilling operations.

Q2: How much does a latest‑generation automated drilling rig cost?

Cost depends on configuration, depth rating, and automation level. For a standard AC VFD land rig (3,000‑5,000m) with basic automation (catwalk + iron roughneck), expect USD 2.5‑5 million FOB China. For a fully automated rig (full pipe handling suite + integrated driller’s console + Idrilling compatibility), USD 5‑10 million+ depending on specifications. Contact our sales team for a firm quote based on your requirements.

Q3: What’s the ROI justification for drilling automation?

Four core value drivers: safety (remove crews from red zone, reduce HSE incidents), efficiency (20‑30 second per connection time savings), consistency (repeatable connections reduce non‑productive time from errors), and well quality (consistent torque and positioning improves zonal isolation and reduces remedial work). For a typical land rig on a multi‑well pad, payback is typically 12‑24 months. For deep wells (9,000m) or offshore operations, payback can be significantly faster due to higher day rates.

Q4: What’s Idrilling (Yinglong), and how does it relate to SJ rigs?

Idrilling is Sinopec’s first self-developed scientific drilling system, integrating IoT sensing, scientific decision-making, and closed-loop control, using the "Great Wall Large Model” to automatically generate drilling plans [15†L4-L6]. As a Sinopec subsidiary, SJ’s drilling rigs are designed to be Idrilling‑ready and Idrilling‑integrated. This gives SJ rigs access to Sinopec’s R&D capabilities that independent manufacturers cannot match. The system has been applied in nearly 400 wells, achieving average ROP increase of 19.34% and average drilling cycle reduction of 12.93%.

Q5: Can your AC VFD drilling rigs be used for workover operations?

Yes. Our XJ series self-propelled workover rigs (XJ150 through XJ1200, 300–2,250 kN max static load, 235–1,300 HP) incorporate the same VFD technology and automation features as our drilling rigs — automated catwalks, automated lifting/lowering of drill pipes, and one‑click activation of automated drill feeding.

Q6: What’s the typical lead time for a latest‑generation drilling rig?

• Standard AC VFD land rig (3,000‑5,000m, truck/trailer mount): 9‑12 months from order confirmation

• Deep well rig (6,000‑9,000m, skid-mounted): 12‑15 months

• Fully automated rig package: 12‑18 months depending on automation scope

• Retrofit automation kits: 3‑6 months

The 9,000‑meter rigs delivered to Kuwait were designed, manufactured, and first unit shipped in just 9 months [4†L28-L29].

Q7: Can you retrofit automation to my existing rig, or do I need a new rig?

Retrofit is absolutely possible — and often the smarter financial decision for operators with existing rig fleets. Our retro kit includes automated catwalk, manipulator, and control interfaces that bolt onto existing floor steel without welding. The dual driller integrated control system can be added to most AC rigs. Total installation: 2‑4 weeks on site. This is a significant market trend — retrofits are a major segment of the robotic drilling market.

Q8: What’s the environmental impact of your VFD drilling technology?

VFD integration improves energy efficiency by 30‑40% compared to conventional DC systems, directly reducing fuel consumption and CO₂ emissions [9†L14-L16]. For operators using hybrid diesel‑battery systems, CO₂ reduction of 20‑25% is achievable. AC‑powered rigs also produce less noise, fewer emissions, and better power distribution than conventional drives
