Why Choose SJ Petro for Your Desert Fast‑moving Drilling Rig?
1. We Hold the China National Invention Patent for Quick‑Assemble Rig Design
The concept of "a drilling rig capable of fast disassembly and assembly and its moving method” is a registered invention in China. SJ Petro is the original developer, not a copycat. When you buy our desert fast‑moving rig, you are buying a design that has been legally protected and commercially proven for years.
2. Field‑Proven with Sinopec – the Largest International Land‑Rig Operator in Kuwait
Sinopec operates the largest international land‑rig fleet in Kuwait – 44 rigs currently deployed, backed by contracts worth nearly US$400 million. Our desert fast‑moving technology is the direct engineering descendant of that decade‑long field experience. You are not beta‑testing a "desert” concept; you are deploying a platform refined across thousands of wellbores.
3. From One Design, a Full Depth Portfolio – No Over‑Spec, No Under‑Power
Because the ZJ40DBT, ZJ50DBT, ZJ70DBT and ZJ90DBT share a common architectural philosophy, you can standardise your fleet across multiple depth ratings while keeping common spare parts, similar rig‑up procedures and interchangeable crew training. This compatibility directly reduces operating costs across a multi‑rig campaign.
4. Complete One‑Stop Supply – From Rig to Mud System to Downhole Tools
SJ Petro does not stop at the drill floor. As a wholly‑owned Sinopec Group subsidiary, we supply the full suite of oilfield equipment: drawworks, top drives, mud pumps, solids‑control systems (designed specifically for desert fast‑moving rigs), downhole tools, coiled tubing units and fracturing fleets. You get a single contractual partner for the entire drilling spread.
5. Engineered for the Desert Right Down to the Solids‑Control Tank
Many "desert rigs” are standard machines sent to the desert. Ours is not. The desert fast‑moving rig's solids‑control system uses a unique tank‑bottom design and integrated sand‑cleaning structure, meeting zero‑discharge requirements in environmentally sensitive deserts. The reserve tanks and mixing skids are self‑back‑skid‑type, and the suction tank and shale‑shaker tank are designed to be moved as a whole unit – not disassembled and rebuilt at each site.
6. API‑Certified, Third‑Party Inspection Always Welcome
Our desert fast‑moving drilling rigs are designed and manufactured to API 4F (masts and substructures), API 7K (drawworks), API 8C (top drive) and API Q1 (quality management). Full material traceability, weld maps and pressure‑test certificates are supplied with every rig. Third‑party inspection (ABS, DNV, BV, SGS) can be present at any stage of fabrication.
7. Global Service and Spares – Wherever Sand Meets Steel
-
Regional support hubs in Dubai (Middle East), Houston (Americas) and Singapore (Asia‑Pacific) stock desert‑specific spares: sand‑resistant seals, heavy‑duty tyres, trailer axle assemblies and AC VFD components.
-
24/7 remote diagnostics via integrated system data logging – our engineers can log in (with your permission) to troubleshoot drive parameters or control‑logic issues.
-
On‑site commissioning and training included with every rig.
FAQ – Desert Fast‑moving Drilling Rig
Q1: Why is a "desert fast‑moving” rig better for the Middle East than a standard land rig?
A: A standard land rig requires a crane for every major component lift during rig‑up and rig‑down – a process that takes days in 50 °C heat. The desert fast‑moving rig uses trailer‑borne modules and hydraulic self‑erecting mast, so it can move without a crane. In open desert terrain, this translates to rig‑move times measured in hours rather than days. Additionally, every component is sealed against fine sand, with oversized cooling to handle ambient temperatures up to 55 °C.
Q2: What is the typical rig‑up and rig‑down time for a desert fast‑moving rig?
A: With a trained crew of 6‑8 people, the ZJ40DBT can be fully rigged up and ready to spud in 16‑24 hours. Rig‑down and preparation for transport can be completed in a similar timeframe. The ZJ50DBT and ZJ70DBT models take slightly longer (24‑36 hours) due to their larger component sizes. Compared to a conventionally modular rig that may require 5‑7 days, the fast‑moving advantage is substantial.
Q3: How does the rig protect itself against sandstorms?
A: The desert fast‑moving rig is fitted with multiple layers of protection:
-
Pressurised control cabins maintain positive internal pressure, keeping fine dust out.
-
Cyclonic pre‑filters on all engine air intakes remove >95% of airborne sand.
-
Sealed electrical enclosures rated to IP56 / IP66.
-
Sand‑tolerant hydraulic seals and bearing shields on all moving chassis components.
In severe sandstorms, operations can be paused, but the rig will remain undamaged.
Q4: Can I add a walking system to a desert fast‑moving rig for cluster pads?
A: Yes. The desert rig family offers a hydraulic walking system as a factory or field‑retrofit option. When walking is engaged, hydraulic lift cylinders raise the entire rig off its trailers, traverse cylinders move it to the next wellhead, and steering turntables allow rotation. The rig can walk between wellheads on a pad without dismantling the mast or lowering the substructure, slashing inter‑well moving time from days to hours.
Q5: How many tonnes or modules does it take to move the rig between fields?
A: The ZJ40DBT is packaged into approximately 11 trailer‑mounted modules; the larger ZJ70DBT uses 13‑14 modules. Each module is designed to be road‑legal without special permits in most Middle Eastern countries. Total transport weight for a complete ZJ50DBT spread is approximately 220‑270 tonnes, depending on optional equipment.
Q6: What kind of power options are available for the desert rig?
A: The standard configuration uses diesel‑electric AC VFD. For operations near grid power, we offer a grid‑connected AC VFD version that reduces fuel consumption and lowers sound emissions. For remote desert locations with natural gas availability, we can supply a dual‑fuel (diesel + natural gas) or gas‑electric package – already proven in other Sinopec desert applications.
Q7: Do you offer training for the rig‑up and walking procedures?
A: Absolutely. Every desert rig sale includes on‑site training for your crew covering:
-
Trailer alignment and module assembly (no crane)
-
Mast and substructure hydraulic erection
-
Walking system operation (where equipped)
-
Sandstorm shutdown and restart protocols
-
Basic maintenance of desert‑rated components
We also provide full colour illustrated manuals and laminated quick‑reference checklists.
Q8: Can I get a desert fast‑moving rig that also works in cold desert climates (‑45 °C)?
A: Yes. Our "Low‑Temp Desert” package adds heated enclosures, cold‑start engine systems, low‑temperature lubricants and arctic‑grade seals. This allows the same rig to operate year‑round in regions such as northern Kazakhstan or the Mongolian Gobi that see 0 °C to +55 °C seasonal extremes with −45 °C winter lows.
Q9: What is the typical lead time for a desert fast‑moving drilling rig?
A: A standard ZJ40DBT or ZJ50DBT can be delivered in 6‑8 months from order confirmation. Larger models (ZJ70DBT, ZJ90DBT) require 8‑10 months. Customised packages (walking system, dual‑fuel, low‑temp option) add 2‑3 months to the lead time. Expedited delivery is available for urgent projects – please contact us.
Q10: How does your desert fast‑moving rig compare to offerings from Western manufacturers?
A: Our rigs are API‑certified to the same standards as any Western supplier. The key differences are:
-
Price: typically 20‑30 % lower due to Sinopec's integrated manufacturing base.
-
Local support: deep footprint in Middle Eastern markets, backed by a global maintenance network.
-
Proven adaptation: hundreds of such rigs have operated in Kuwait, Saudi Arabia and the UAE for well over a decade through the Sinopec fleet.
