The 750HP Skid-Mounted Rig (XJ750/ZJ30) is a high-power, heavy-duty fixed petroleum drilling and workover solution professionally designed for long-term stationary oilfield operations. Different from truck-mounted mobile rigs, this skid-based unit adopts integrated skid base integral installation structure, with all power, hydraulic, control and lifting systems centrally assembled on a reinforced heavy-duty skid frame. Equipped with dual high-efficiency diesel engines forming 750HP rated power output and matched with a high-rigidity lattice mast system, it supports 3000m medium-deep drilling and 7000m ultra-deep well workover operations. Featuring ultra-high structural stability, strong load-bearing capacity and continuous working reliability, the rig is fully compliant with API 4F international petroleum machinery standards. It is ideal for fixed well clusters, central oilfield zones and long-cycle engineering projects, delivering stable, high-efficiency and low-maintenance construction performance for standardized large-scale oilfield operations.
Adopts dual matched diesel engine combined power system with 750HP comprehensive rated power, providing sufficient and stable torque reserve. It avoids power fluctuation and attenuation during long-term full-load operation, perfectly adapting to continuous heavy-load drilling, tripping and downhole overhaul of medium and ultra-deep wells.
The whole machine adopts integral reinforced skid base design, with overall structural rigidity and anti-vibration performance greatly improved compared with mobile truck-mounted rigs. It eliminates vehicle shaking and displacement during high-intensity operation, ensuring ultra-precise and stable long-cycle construction for fixed well sites.
Equipped with optimized multi-rope high-strength travelling system and thickened load-bearing components, with reliable hook load performance. It stably copes with heavy tripping, stuck pipe handling and high-resistance downhole operations of 7000m ultra-deep wells, with stronger overload resistance and construction stability.
Adopts centralized modular layout for power unit, hydraulic system, mud system and control cabin. All core components are reasonably arranged with reserved independent maintenance spaces, simplifying daily inspection, fault troubleshooting and routine maintenance, effectively reducing long-term operation costs.
Optimized foundation fixing structure and overall stress distribution design, suitable for long-term fixed installation in standardized oilfield zones. It supports 24-hour uninterrupted continuous operation, with excellent durability and environmental adaptability in desert, Gobi and field fixed working scenarios.
Matched with enclosed integrated control cabin and full-process data monitoring system, equipped with multi-level safety interlock and overload protection devices. It realizes visualized, automated and safe operation of whole-process construction, reducing manual operation risks and improving overall construction standardization.

The following questions address common equipment selection and operating considerations.
Unlike mobile truck-mounted rigs, the 750HP skid-mounted rig adopts fixed skid base installation, featuring higher overall structural stability, stronger anti-vibration performance and longer continuous operation life. It is more suitable for long-term fixed well cluster construction, while truck-mounted rigs are for frequent relocation operations, realizing targeted application scenario differentiation.
No. The whole machine adopts integral skid modular pre-assembled design. All core systems are pre-debugged in the factory. On-site installation only requires foundation fixing and pipeline connection, with simple operation and short commissioning cycle, greatly saving on-site construction time.
The standard model supports 3000m medium-deep well drilling and 7000m ultra-deep well workover. We can adjust core configurations according to customer project demands to meet different depth operation standards.
Yes. The whole machine is optimized for fixed long-cycle working conditions, with reinforced structural components, stable power output and enhanced heat dissipation and wear-resistant systems. It can stably realize 24-hour uninterrupted full-load operation and has excellent long-term working durability.
We provide complete installation drawings, professional technical documents and full-set spare parts supply. We offer long-term remote technical guidance and can arrange professional engineering teams for on-site installation guidance, commissioning and operator training according to project needs.
We have professional R&D and manufacturing experience in high-power skid-mounted drilling and workover rigs, with all 750HP skid-mounted rigs manufactured in strict accordance with API 4F international petroleum industry standards. We focus on customized solutions for fixed oilfield long-cycle operation projects, adopting integral skid stable structure and optimized dual-power system to solve the stability and durability pain points of mobile rigs in fixed-site continuous construction. Every unit undergoes strict factory full-load testing, 24-hour continuous operation debugging and structural stability inspection before delivery to ensure zero failure in long-term field operation. We provide full-process one-stop services including scheme customization, factory pre-assembly, on-site installation guidance, factory acceptance and global shipping. Supported by a complete spare parts supply system and professional petroleum engineering team, we deliver long-term stable after-sales technical support and equipment guarantee for global fixed oilfield projects, effectively reducing customer long-term operation and maintenance costs.
