Key quick install design features:

• Module count – Each rig is broken into a limited number of road‑legal modules (typically 6–11). The ZJ40 desert fast‑moving rig integrates everything into 11 trailer‑borne transport modules. [15†L18-L20]

• Pre‑connected systems – Cables, hoses, and control lines are permanently routed within modules; only a handful of inter‑module connections required at the new wellsite.

• No‑weld assembly – Modules bolt or pin together; no welding means no hot work permits, no structural certification delays.

• Self‑erecting mast – The mast can be raised and lowered using rig‑mounted hydraulics—no crane required for rig‑up or rig‑down.

Application Fields

1. Multi‑Well Pad Drilling (Unconventional Resources)

Shale gas, tight gas, and CBM operations drill dozens of wells from a single pad. Fast‑moving drilling rigs—developed through integrated mechanical and electrical design—achieve dramatic relocation time reductions. [6†L34-L36] Using a cluster drilling slider platform, the rig can be repositioned along skids using hydraulic cylinders without dismantling or throwing out tools. The result: pad‑to‑pad move times measured in hours, not days.

2. Desert & Remote Area Drilling

Desert rig moves are notoriously difficult—soft sand, high ambient temperatures, and long distances between well pads. SJ quick install rigs are specifically designed for these conditions: modular design, integrated towing, rapid moving capabilities, and adaptability to complex desert terrain. [6†L12-L14] The ZJ90DB arrived at the Kuwait wellsite, was assembled by the SP‑8 drilling team, and achieved first spud 73 days ahead of contract schedule.

3. Offshore Platform Modular Drilling

Offshore platforms have limited deck space and crane availability. Modular quick install rigs designed in container‑sized modules can be lifted into place by platform cranes and assembled without major construction work. The Innorig rig design uses container‑sized modules, and the entire drilling set can be delivered in container dimensions.

4. Workover & Well Intervention (Fast‑Move Rigs)

Mobile workover rigs (XJ150 through XJ1200, maximum static load 300–2,250 kN, installed power 235–1,300 HP) share the same modular design philosophy—the power system, transmission system, control system, traveling system, diesel engine, and gearbox are all mounted on the main carrier, saving space and making the rig fast to move.

5. Cluster Well Factory Drilling

Using fast‑moving drilling rigs for cluster horizontal well development enables efficient drilling of well groups in a short period. The rig’s high mobility without disassembly reduces relocation and installation time, thereby improving overall drilling efficiency and reducing drilling and completion costs—making factory‑style operations feasible.

FAQ – Quick Install Drilling

Q1: What does "quick install drilling” actually mean?

Quick install drilling refers to rigs designed for rapid assembly, disassembly, and relocation. Key features include modular design (breaking the rig into a limited number of transportable modules), self‑erecting masts (no crane required for raising/lowering), pre‑connected systems (minimal on‑site wiring/piping), and integrated towing or walking systems for short‑distance moves. The goal: reduce non‑productive rig move time from weeks to days or hours.

Q2: How fast can a quick install rig be moved and reassembled?

Performance depends on distance and terrain:

• Multi‑well pad moves (50‑100 meters): Walking systems reposition the rig in 4–8 hours without any disassembly.

• Short‑distance desert moves (10‑20 km): Late‑generation 1000‑HP rigs reduce move time from 36–40 hours down to 12 hours.

• Long‑distance moves requiring disassembly: The ZJ40 desert fast‑moving rig integrates into 11 trailer‑borne modules, and large‑module transport rigs like the ZJ90DB in Kuwait achieve single‑slot rig‑up in as little as 2 days—approximately 5× faster than conventional rigs.

Q3: What’s the difference between a modular rig and a conventional rig?

Conventional rigs are typically assembled from hundreds of individual components—pumps, engines, drawworks, mast sections, substructure beams, control cabinets. Disassembly requires disconnecting countless lines and fittings, with each component loaded separately.

Modular rigs pre‑integrate components into functional modules (e.g., power module containing engines, VFD, and generators; drilling module containing drawworks, top drive, and control room). Modules are designed to mate quickly—typically with standard inter‑module connectors. The result: disassembly and reassembly take days instead of weeks.

Q4: Can a quick install rig be used for deep wells (7,000‑9,000 meters)?

Absolutely. The ZJ90DB ultra‑deep quick install rig is rated for 9,000 meters and successfully deployed in Kuwait’s northern oilfield with 3,000‑horsepower AC VFD drive. Prior to export, the same rig had drilled 23 wells in China’s northwest region, reaching a maximum depth of 9,270 meters.Modular design applies across all depth ratings.

Q5: Do I need a crane to assemble the rig?

Not for the mast. Our self‑erecting masts use rig‑mounted hydraulics for raising and lowering—no crane required.The 90‑class mast uses a single‑line hoisting structure that reduces lifting components by 50% and saves 60% of raising time. Some modules may still require crane off‑loading from transport vehicles, but the overall crane requirement is dramatically reduced compared to conventional rigs.

Q6: What’s the lightweight structure design, and why does it matter for quick install?

The ZJ90DB features a unique double‑beam double‑triangle mast structure that reduces mast weight by 30% and lifting load by more than 15% compared to similar products.Lighter components mean:

• Fewer truckloads for transport

• Smaller crane requirements

• Faster raising/lowering

• Lower logistics cost

Q7: Can the rig move between wells without disassembling the drill pipe?

Yes—for short pad moves (50‑100 meters) using a walking system. During cluster drilling, a slider platform moved along skis using hydraulic cylinders allows repositioning the mobile drilling rig without additional time spent on throwing out the tool, dismantling, or installing. [5†L34-L38] The pipe stands can remain racked in the derrick. For longer moves, pipe is typically laid down.

Q8: What’s the typical lead time for a quick install drilling rig?

• Standard modular rig (4,000‑5,000m): 9‑12 months from order confirmation

• Deep modular rig (7,000‑9,000m): 12‑15 months

• Fully automated quick install rig: 15‑18 months

The ZJ90DB project—six rigs supplied to Kuwait—was designed, manufactured, and the first unit shipped in just 9 months.

Q9: What certifications do your quick install rigs carry?

Our facilities maintain API Q1, API 4F, API 7K, API 8C, ISO 9001, ISO 14001, and OHSAS 18001 certifications. [2†L6-L8] Complete documentation packages are available for international tenders.
