The 250HP Workover Rig (XJ250) is a mid-tier, high-mobility truck-mounted petroleum workover unit, serving as an upgraded alternative to the entry-level 150HP workover rig. Adopting a mature self-propelled vehicle-mounted chassis and standard 250HP high-efficiency power assembly, this rig balances strong field mobility and medium-load operation capacity, perfectly fitting medium-depth well routine maintenance and conventional well overhaul projects. Optimized with an upgraded high-strength lattice mast and reinforced hoisting system, it stably supports 1800m medium-shallow well workover and minor drilling operations. Featuring integrated modular layout, reliable power transmission and flexible cross-site relocation performance, the equipment fully complies with API 4F and international petroleum machinery industry standards. It is widely applicable for medium and small oilfield block operation, scattered well cluster maintenance, and conventional medium-depth well repair projects, delivering higher load capacity and construction efficiency than 150HP rigs while maintaining excellent cost-effectiveness and field adaptability.
Equipped with a matched high-performance diesel power assembly and professional transmission system, outputting 250HP rated stable power and sufficient torque reserve. Compared with 150HP light-duty rigs, it features stronger power surplus, faster hoisting response and more stable full-load operation, completely meeting the power demand of 1800m medium-shallow well overhaul and complex wellbore treatment.
Adopts upgraded reinforced travelling system and thickened load-bearing structural parts, with greatly improved hook load and overload resistance. It can cope with medium-intensity working conditions such as heavy paraffin removal, casing repair, stuck pipe disposal and medium-depth well tripping operations that entry-level rigs cannot undertake, expanding the scope of on-site operation scenarios.
Built with optimized 6×4/6×6 optional drive chassis, featuring flexible steering, low turning radius and fast travelling speed. The integral vehicle-mounted structure supports rapid cross-well and cross-region relocation without auxiliary hoisting and transportation equipment, greatly improving the operation switching efficiency of dispersed medium-shallow well clusters.
Scientifically integrates power, hydraulic, hoisting and control modules with standardized compact layout, occupying small construction space. Equipped with optimized hydraulic automatic mast lifting system and intuitive centralized operation platform, it simplifies operating procedures, reduces labor intensity and improves overall construction efficiency.
Adopts mature industrial-grade core components and optimized transmission structure, with stable mechanical performance and low failure rate. The universal vulnerable parts design simplifies daily inspection and maintenance work, effectively reducing long-term operation and spare parts investment, and achieving outstanding comprehensive economic benefits for medium-volume oilfield maintenance projects.
Upgraded dust-proof, wear-resistant and heat dissipation structure, with expanded adaptive temperature range and stronger terrain passing performance. It can operate stably in flat oilfields, suburban well areas, mild desert and low-altitude hilly terrains, adapting to diversified complex field working environments.

The following questions address common equipment selection and operating considerations.
The 250HP XJ250 workover rig features upgraded 250HP high-power output and higher hook load capacity, supporting 1800m medium-shallow well operations, which is deeper than the 1200m limit of 150HP rigs. It has stronger medium-load resistance and can handle complex wellbore overhaul working conditions, while retaining high mobility and cost-effectiveness, filling the performance gap between light-duty and medium-duty workover rigs.
Yes. Adopting self-propelled truck-mounted chassis design, the rig features flexible travelling and small turning radius. It can realize rapid integral transfer without auxiliary hoisting equipment, perfectly adapting to frequent cross-well and cross-region operation switching of dispersed medium-shallow well clusters.
The standard model is designed for 1800m medium-shallow well workover operations. We can adjust core configurations appropriately according to customer on-site working conditions to meet customized medium-depth well operation requirements.
It is specially designed for medium-shallow well medium-load overhaul and daily maintenance. It can efficiently complete conventional well flushing, paraffin removal, casing repair and medium-intensity tripping operations, and is widely applicable for medium and small oilfield blocks and scattered well cluster projects with frequent relocation and moderate load demands.
We provide complete equipment operation and maintenance manuals, full-set conventional spare parts supply and long-term free remote technical guidance. We can also arrange professional teams for on-site equipment commissioning, installation guidance and operator training according to project requirements.
We possess mature R&D and standardized manufacturing capabilities for 250HP XJ250 medium-duty workover rigs, with all products strictly manufactured in accordance with API 4F and international petroleum machinery industry standards. Targeted at medium-shallow well medium-load overhaul and frequent relocation operation scenarios, this rig upgrades power and lifting performance on the basis of light-duty rigs, avoiding performance surplus and high cost of high-horsepower heavy-duty rigs. Adopting mature chassis matching and reliable transmission structure, the equipment features stable operation, strong terrain adaptability and low comprehensive failure rate. Every rig undergoes strict factory full-load debugging and field simulation testing before delivery to ensure stable and efficient on-site operation. We provide full-process one-stop services including personalized scheme customization, standardized production, global shipping and professional after-sales technical support, helping customers improve medium-shallow well operation efficiency and reduce comprehensive oilfield maintenance costs.
