The Truck Mounted Workover Rig XJ1000 is a super heavy duty self propelled workover rig engineered for 6000-7000m ultra deep well maintenance and reconstruction tasks.
The Truck Mounted Workover Rig XJ1000 is a super heavy duty self propelled workover rig engineered for 6000-7000m ultra deep well maintenance and reconstruction tasks. Designed and certified in accordance with API 4F, API 7K and ISO9001 international industrial standards, the entire equipment adopts ultra high load integrated truck chassis design. It realizes full self driving transportation without disassembling core components, delivering extreme mobility for ultra deep well block operations. As a top grade heavy duty workover unit, it is mainly used for ultra deep oil and gas well major overhaul, complex downhole accident treatment, heavy load pipe string running and pulling, and large scale reservoir stimulation. It is the preferred core equipment for ultra deep oilfield high standard workover and well restoration projects worldwide.
The whole machine adopts customized ultra heavy duty off road truck chassis, with all high load core components such as super large derrick, heavy duty drawworks and high torque transmission system highly integrated. It meets full road driving standards and supports rapid self propelled transition between scattered ultra deep well sites without external towing equipment.
Equipped with reinforced thick wall vertical folding derrick, which undergoes finite element stress fatigue analysis to ensure overall structural stability under long term ultra high hook load. Full hydraulic automatic erecting and folding process eliminates crane dependence, greatly improving construction efficiency for ultra deep well operations.
Adopts upgraded enhanced mechanical transmission system matched with large flow hydraulic power assist. It outputs stable and powerful lifting torque under ultra deep well complex variable load conditions, effectively adapting to high intensity heavy load tripping and overhaul operations with strong impact resistance and stable power output.
Built in mechanical anti fall locking device, hydraulic overload self protection system, emergency rapid braking mechanism and whole machine operation interlock protection. It comprehensively prevents operational risks such as pipe string falling, equipment overload and misoperation during ultra deep well heavy duty construction.
All key load bearing and electrical components adopt low temperature anti brittle, high temperature anti aging and salt fog anti corrosion materials. The whole machine is optimized for desert high temperature, plateau cold and windy dusty working conditions to support year round continuous heavy load operation.

When a service company's wells span from medium-deep producers out to 7000 m completions, the most expensive gap on the roster is the one between a 1500 kN workover unit and a true super-heavy one. The XJ1000 fills that band: a 7000 m working depth on 73 mm pipe, a 3150 kN static hook and 1000 HP of lifting train, dedicated to major repair rather than to drilling. That is the niche — pulling heavy completion and test strings, freeing stuck pipe, remediating collapsed wells on deep leases that a mid-class unit simply cannot reach. The integrated heavy off-road carrier moves itself between scattered ultra-deep locations at up to 75 km/h; core assemblies stay bolted on, no tractor is called in, and the mast goes up hydraulically with no crane on the pad.
Specify three things on an XJ1000 inquiry. The heaviest completion string actually run in your deepest wells — match the 3150 kN hook to that, not to the 7000 m signboard. Whether the campaign is planned major overhaul or emergency stuck-pipe call-outs, because that changes the braking and line-system duty. And how often the spread relocates between ultra-deep pads, since the self-propelled chassis is priced around that mobility. The -40°C to +55°C envelope is standard; flag desert heat or plateau cold if you want the dust-sealing or winterised package quoted.
For operators standardising on one fleet, we can document interchangeability of the mast, drawworks and pump packages across models.
Optional ultra low temperature cold resistant package with full hydraulic heating and cold start system; desert high temperature heat insulation and full dust sealing upgrade; coastal salt spray heavy duty anti corrosion coating treatment.
Customize chassis load parameters, braking system, tire configuration and road lighting system to meet highway certification requirements of different countries and regions.
Support enhanced high power diesel engine configuration and customized power output curves to adapt to ultra deep well super heavy load operation demands.
Optional digital monitoring system, remote real time data transmission, intelligent fault early warning and automatic pipe handling auxiliary module.
Support exclusive equipment color spraying, customer brand logo customization, and project specific full set of wear parts and spare parts package delivery.
