1. With the adoption of advanced digital AC frequency conversion electric transmission and the integration design of machine, electricity, liquid, gad and digital control, the skid-mounted oil drilling rigs are more simplified on structure.
2. Equipment of mobile oil 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 oil 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 1500HP skid-mounted oil drilling rigs adopts dual PLC design and improves the reliability of the system.
Applications
1500HPSkid-Mounted Rig,Skid-Mounted Oil Drilling Rigs,China Mobile Oil Rigs is engineered for 2,500 to 4,000 meter wells. It is built for reliable daily operation in demanding onshore oil and gas environments, with design choices that match the real-world needs of mid-sized drilling contractors working on medium-deep field development programs.
- Primary use: deeper development wells and directional drilling projects.
- The rig/unit is a common sight in mature onshore basins across the Middle East, Central Asia, Africa, and Southeast Asia.
- It is selected by operators who value straightforward maintenance and locally available spare parts over overly complex control systems.
15px;">Our skid rigs use AC variable frequency electric drive, which simplifies the power transmission system compared to older mechanical drive rigs. This design reduces moving parts, lowers maintenance requirements, and gives the driller finer control over hook load and rotary speed.
- The control system uses common industrial PLC components that are available worldwide.
- Drawworks and rotary table components are interchangeable with common API-spec drilling rig spares.
- Optional cold-weather packages are available for rigs operating in northern climates.
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: What mud pump configuration comes standard?
A: This rig typically comes with two F-1600 triplex mud pumps, which provide enough flow rate and pressure for most medium-depth drilling programs.
Q: Can the drawworks handle directional drilling workloads?
A: Yes, the AC variable frequency drawworks provides smooth speed control that works well for directional and horizontal drilling operations.
Q: How much load can the substructure support?
A: The substructure is rated for the full hook load capacity of the rig, plus the BOP stack and surface equipment loads required for standard drilling operations.
Maintenance Tips
To maximize rig uptime, we recommend sticking to a simple preventive maintenance schedule:
- Inspect drawworks brakes and wireline condition on a daily basis.
- Change engine oil and filters per the manufacturer's recommended interval.
- Keep electrical enclosures sealed and clean, especially in dusty desert operating environments.
- Stock common wear parts (brake pads, seals, filters) locally to avoid long downtime waiting for spares.
