1. With the adoption of advanced digital AC frequency conversion electric transmission and the integration design of machine, electricity, liquid, gas and digital control, the skid-mounted drilling rigs are more simplified on structure.
2. Equipment of drilling rigs is installed at low position and integrated hoist,which reduces the workload of aerial work and improves the safety.
3. Electric transmission adopts vector frequency conversion drive system and realizes the fully digital control operation.
4. The reserve interface for remote fault diagnosis expert system of skid-mounted drilling rigs can realize control parameters and drilling parameters (signal) collection, display, storage, print remote monitoring and management.
5. Enlarging the parameter range of bit pressure, drilling rate, pump pressure and pump capacity realizes the high precise control and improves drilling crafts. With the adoption of frequency conversion technology, the winches are suspended which change the traditional way of driller operation.
6. The operation control system of land drilling rigs adopts dual PLC design and improves the reliability of the system.
Applications
The 1000HP skid-mounted drilling rig is our entry-level mid-range drilling unit — perfect for drilling contractors who need professional drilling performance without the cost of a larger rig. It's the most cost-effective way to get into skid-mounted drilling.
- Primary use: medium-depth development well drilling on wells up to 4,000m depth.
- Ideal for drilling contractors who are moving up from truck-mounted rigs and need more power, but aren't ready for a full-size deep drilling rig.
- Commonly deployed on development drilling programs where wells are concentrated in a single field area.
The Cost-Effective Choice for Development Drilling
For many drilling contractors, the 1000HP class is the sweet spot. It has enough power to handle the majority of onshore development wells — typically 2,000 to 4,000 meters deep — without the high capital cost and operating expenses of a larger 1500HP or 2000HP rig.
This rig is especially popular with new drilling contractors who are building their fleet. It delivers all the essential features you need — AC VFD drive, dual PLC control, F-1300 mud pumps — at a price point that makes economic sense for medium-depth drilling projects.
And because it's built on the same platform as our larger rigs, you get the same quality and reliability, just with less horsepower. It's the smart choice when your drilling program doesn't require the extra power of a larger rig.
Choosing the Right Skid-Mounted Rig Size
For wells between 2,000m and 4,000m depth, the 1000HP skid-mounted rig delivers the right balance of drilling power and cost-effectiveness.
If your wells are shallower, the 750HP Skid-Mounted Rig offers a more budget-friendly option. For deeper wells or heavier drilling operations, step up to a 1500HP Skid-Mounted Rig for more power and capacity.
FAQs
Q: What depth wells can this rig drill?
A: The 1000HP skid-mounted rig is rated for drilling operations up to approximately 4,000 meters depth.
Q: How is this different from the 750HP rig?
A: The 1000HP rig has more power and can drill deeper wells (up to 4,000m vs 3,000m for the 750HP). It's a step up in capability for contractors who need more drilling power.
Q: Is this rig a good choice for a new drilling contractor?
A: Yes, absolutely. The 1000HP class is the most popular entry point for contractors moving into skid-mounted drilling — it offers professional performance at a manageable price point.
Q: What mud pumps are used?
A: This rig is equipped with two F-1300 triplex mud pumps, providing reliable circulation for medium-depth drilling operations.
Quality Standards and Certifications
The 1000HP skid-mounted drilling rig is built to meet international industry standards. Here are the key certifications and standards:
- API Spec 4F: This is the API standard for drilling and well servicing rigs. It covers the design, manufacture, and testing of drilling rigs. All reputable rig manufacturers build their rigs to API Spec 4F.
- API Spec 7K: This is the API standard for drilling equipment — drawworks, rotary tables, top drives, and other components.
- ISO 9001: This is the international quality management standard. It ensures that the manufacturer has a consistent quality management system in place.
- CE marking: If you're operating in Europe, or in countries that adopt European standards, the rig needs CE marking, which indicates compliance with European health, safety, and environmental protection standards.
Site Installation Requirements
A 750HP skid-mounted drilling rig is designed for long-term installation at a fixed well site, with typical rated drilling depth up to 2,800 meters. Before the rig arrives, crews need to prepare a level compacted ground pad to support the combined weight of the rig substructure, draw works, and pumping units — uneven ground can cause excessive mast vibration during drilling and shorten component life.
Once the rig components arrive on site, a 6-person installation crew can complete rig-up in about 3 working days, including aligning the mast, connecting the mud line, and commissioning the power system. Unlike truck-mounted rigs, skid units do not need to be leveled on outriggers for each job, so they are the preferred choice for drilling campaigns where the rig will stay on the same location for several months at a time.
We recommend keeping at least 20 meters of clear space around the rig pad for mud tanks, pipe racking, and service vehicle access, which is critical for safe operations during peak drilling periods.
FAQs
Q: How long does it take to drill a well with a 1000HP rig?
A: It depends on the depth of the well, the formation, and the conditions. A typical 3,000-meter onshore well takes 20-40 days to drill, from spud to total depth. Shallow wells take less time; deeper wells take more.
Q: How many people are needed to operate a 1000HP rig?
A: A typical drilling crew is 8-12 people — a driller, an assistant driller, derrickhands, floorhands, a motorman, and a mechanic. On a 12-hour shift basis, you need two crews, so 16-24 people total.
Q: What's the fuel consumption of a 1000HP rig?
A: It depends on the drilling conditions, but typically a 1000HP rig uses 500-1,000 liters of diesel per hour, when drilling. When idling, it uses less. Fuel is one of the biggest operating costs for a drilling project.
Q: How long does a 1000HP rig last?
A: With proper maintenance, a 1000HP rig can last 20-30 years, or 50,000-100,000 drilling hours. Many rigs built in the 1980s and 1990s are still in service today, especially in the Middle East and Asia.
