The Truck Mounted Workover Rig XJ1200 is an ultra-heavy-duty self-propelled workover rig designed for 7000-8000m ultra-deep well professional overhaul.
The Truck Mounted Workover Rig XJ1200 is an ultra-heavy-duty self-propelled workover rig designed for 7000-8000m ultra-deep well professional overhaul and complex downhole treatment operations. Fully compliant with API-4F, API-7K and ISO9001 international quality and safety standards, the whole machine adopts a customized super-heavy-load special truck chassis, realizing highly integrated structural layout. It supports self-driving road transportation without disassembly of core components, achieving rapid mobilization and deployment for ultra-deep well blocks. As a top-tier flagship workover equipment, it is mainly used for ultra-deep oil/gas well major overhaul, complex downhole accident handling, super-heavy load pipe string tripping, and large-scale reservoir stimulation reconstruction. It is the core high-end supporting equipment for ultra-deep oilfield development and high-difficulty well repair projects at home and abroad.
Adopts customized ultra-heavy-duty off-road truck chassis with enhanced bearing structure. Core components including oversized derrick, high-power heavy-load drawworks and high-torque transmission system are highly integrated. The whole machine meets international road transportation standards and can be self-propelled across well sites, eliminating the need for large towing equipment and greatly improving construction mobility.
Equipped with thickened high-strength alloy vertical folding derrick, verified by full-working-condition finite element fatigue analysis. It features strong deformation resistance and structural stability under long-term ultra-high hook load. Full hydraulic automatic erecting and folding process realizes crane-free rapid setup, effectively shortening ultra-deep well operation preparation cycle.
Matched with upgraded enhanced mechanical transmission and large-flow hydraulic assist power system. It outputs stable and powerful lifting torque, adapts to extreme working conditions such as high downhole pressure, complex stratification and frequent variable loads, and maintains high-efficiency and low-failure continuous heavy-load operation.
Equipped with mechanical anti-drop locking device, hydraulic overload automatic protection, emergency braking system and whole-machine interlock safety mechanism. It comprehensively prevents operational risks such as pipe string falling, equipment overload and human misoperation, ensuring high safety of ultra-deep well heavy-duty construction.
Key structural parts adopt anti-corrosion, anti-aging and low-temperature anti-brittle materials; electrical and hydraulic systems are equipped with dust-proof, heat-insulating and cold-start auxiliary devices. The whole machine can operate stably all year round in desert high-temperature, plateau cold and windy dusty extreme oilfield environments.
