The Truck Mounted Workover Rig XJ650 is a heavy duty self propelled workover rig designed for 4500-5500 m deep well maintenance and reconstruction operations.
The Truck Mounted Workover Rig XJ650 is a heavy duty self propelled workover rig designed for 4500-5500 m deep well maintenance and reconstruction operations. Fully compliant with API 4F, API 7K and ISO9001 international standards, the entire unit is highly integrated on a heavy load off road truck chassis. It features one piece transportation without major disassembly, enabling fast self driven relocation between well sites. This model is widely used for deep oil and gas well overhaul, downhole string replacement, plug removal, paraffin treatment, and reservoir stimulation. Optimized for heavy load workover scenarios and complex field environments, it serves as reliable core equipment for large scale deep oilfield daily maintenance and well repair projects.
All core working components including derrick, heavy load drawworks, power transmission and control system are compactly mounted on a high strength truck chassis. Independent road traveling capability eliminates tractor dependency, greatly improving maneuverability for dispersed deep well blocks.
Reinforced vertical folding derrick with thickened wall structure provides superior integral rigidity under heavy lifting loads. Full hydraulic automatic erecting and folding requires no field crane support, drastically cutting auxiliary equipment costs and rig setup time.
Adopts upgraded heavy duty mechanical transmission matched with optimized hydraulic assist system. It delivers powerful and steady lifting force under variable downhole load conditions, adapting to frequent start stop and high intensity continuous workover operations with high efficiency and low failure rate.
Equipped with mechanical limit locks, hydraulic overload protection, emergency braking system and anti fall safety devices. Multi dimensional safety interlocks effectively avoid overloading, misoperation and pipe string falling risks during deep well workover.
Key load bearing parts adopt high strength alloy materials with anti corrosion and anti aging treatment. Standardized universal wearing parts enable convenient global after sales maintenance and rapid on site replacement.

A 4500 m well that is recompleted or deepened toward 5500 m has a habit of quietly outgrowing the workover spread that served it last campaign — and the first trip that fails to pull the completion free is usually a hook-load problem, not a depth problem. The XJ650 truck mounted workover rig sits on that boundary: a 5500 m working depth on 73 mm pipe, an 1850 kN static hook and 650 HP of lifting train, aimed at heavier deep-well repair, tubing and tool replacement, and medium-to-large stimulation support. Its reinforced self-raising mast carries the rigidity those deeper pulls demand, and the integrated carrier drives itself between mountainous, Gobi and desert deep-well leases at up to 80 km/h with nothing towing behind.
An XJ650 quote is built around three inputs: the heaviest deep completion you expect to pull, the depth spread across your deep-well block, and whether the work is routine heavy repair or occasional emergency response after a downhole incident. Benchmark the 1850 kN hook against real string weights rather than the 5500 m nameplate — if your block pushes toward 6000 to 7000 m, the XJ1000 super-heavy class is the honest step-up.
