The Truck Mounted Workover Rig XJ550 is a high-efficiency self-propelled oilfield workover rig developed for 3500-4500m medium-deep well overhaul and maintenance operations. Manufactured in strict accordance with API-4F, API-7K and ISO9001 international quality standards, the whole equipment is fully integrated on a heavy-duty off-road truck chassis. It features integrated structure design without repeated disassembly during well-site transfer, realizing rapid self-driving relocation. This rig is mainly used for conventional oil and gas well workover, paraffin removal, plugging removal, well repairing and reservoir stimulation operations. It is highly adaptable to scattered well points, mountainous oil areas and frequent migration operation scenarios, serving as mainstream core equipment for daily oilfield maintenance and reconstruction projects.
Derrick, drawworks, power transmission system and operating mechanism are highly integrated on the professional heavy-duty truck chassis. The whole rig can travel on public roads independently without tractor cooperation, realizing fast cross-well-position transfer and greatly improving field operation mobility.
Equipped with high-reliability hydraulic telescopic and lifting system. The derrick can be erected and folded automatically on site without large-tonnage cranes, which simplifies well-site deployment procedures, saves auxiliary construction costs and shortens operation preparation cycle.
Adopts optimized mechanical transmission matching hydraulic auxiliary power, realizing stable output of lifting torque and flexible speed regulation. It meets the frequent start-stop and variable-load working characteristics of workover operations, with high transmission efficiency and low energy consumption.
The overall structural layout is optimized with a low center of gravity, ensuring driving stability and on-site operation safety. Equipped with multiple mechanical limit protection and hydraulic safety interlock devices to prevent overload and misoperation risks during workover construction.
Key components adopt anti-corrosion and anti-aging treatment, adapting to desert, Gobi and field harsh working environments. Standardized general wearing parts simplify daily maintenance and global after-sales spare parts replacement.
