1. The 750HP drilling rigs adopt modular design which needs less installation and transportation times. It also can move and disassembly quickly.
2. The mast of mobile skid-mounted rig is front open-face, "K” type. It is two-section telescoping structure. It raises and goes down by its own power. The substructure is high-low position hydraulic telescoping structure,and its installation is on low position.
3. The rig is driven and controlled by AC frequency conversion mode.
4. It has special driller console. All air hose and oil tubes of the mobile drilling rigs adopt quick acting coupling and are remarked clearly.
Applications
750HP Skid-Mounted Rig,Mobile Skid-Mounted Rig,China Mobile Drilling Rigs Manufacturer is engineered for 1,500 to 2,800 meter production 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 small to mid-sized drilling contractors operating in mature onshore fields.
- Primary use: shallow to medium-depth development wells and workover operations.
- 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.
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 for 114mm drill pipe. Before the rig arrives, crews need to prepare a level compacted ground pad to support the combined weight of the rig substructure, drawworks, and pumping units — uneven ground can cause excessive mast vibration during drilling operations and shorten component service life.
Once the rig components arrive on site, a 6-person installation crew can complete full rig-up in about 3 working days, including aligning the telescoping mast, connecting the mud circulation line, and commissioning the AC variable frequency power system. Unlike truck-mounted workover rigs, skid units do not need to be leveled on outriggers for each job move, so they are the preferred choice for long drilling campaigns where the rig will stay on the same well 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. As a leading China oilfield equipment manufacturer, we design these mobile skid rigs to meet the common needs of drilling contractors across the Middle East, Central Asia, and Africa, where spare parts availability and simple maintenance are top priorities.
FAQs
Q: What depth rating is this small skid rig designed for?
A: This 750HP class rig is rated for wells up to 2,800 meters, which makes it a cost-effective choice for shallow to medium-depth development work.
Q: Can this rig be equipped with cold-weather features?
A: Yes, we can add arctic packages including heated cabins, engine block heaters, and low-temperature hydraulic fluid for operations in cold climates.
Q: What is the footprint when rigged up?
A: The standard substructure layout is optimized for smaller well pads, which is useful for mature fields with limited space between wells.
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.
