Land AC VFD Drilling Rig ZJ90DB

The Land AC VFD Drilling Rig ZJ90DB is a super heavy-duty skid-mounted full AC variable frequency land drilling rig, customized for 7000-9000m ultra-deep.

Product overview

The Land AC VFD Drilling Rig ZJ90DB is a super heavy-duty skid-mounted full AC variable frequency land drilling rig, customized for 7000-9000m ultra-deep well drilling and completion operations. Complying strictly with API-4F, API-7K and ISO9001 global industry standards, the whole rig adopts fully modular skid split structure, supporting standard containerized multimodal transportation and rapid on-site assembly. As a flagship ultra-deep well drilling equipment, it is exclusively applicable to ultra-deep conventional oil and gas reservoirs, pre-salt formation resources, deep tight oil and shale gas large-scale block development. With ultra-large load capacity, extreme formation adaptability and long-cycle uninterrupted operation capability, it serves as core strategic equipment for global large-scale ultra-deep oilfield exploration and national key energy engineering projects.

Core innovative advantages and structural features

Ultra-large Modular Skid Integrated Design

All core components including super-large derrick, heavy-duty box substructure, high-power drawworks, power assembly and intelligent control cabin are independently skid-mounted. The optimized split size fully adapts to international cross-border logistics standards, effectively reducing overseas transportation costs and on-site installation cycle for ultra-deep well projects.

Super-power Full AC-VFD Independent Drive System

Equipped with high-grade independent variable frequency drive units for drawworks, rotary table and main mud pump. It delivers ultra-high stable torque at low speed, realizes stepless precise regulation of drilling parameters, and effectively suppresses drill string resonance and vibration in high-pressure ultra-deep complex strata, greatly improving ultra-deep well drilling safety and efficiency.

Extreme High-strength Anti-fatigue Structure

Adopts upgraded super-large K-type open-front derrick and reinforced heavy-load substructure. Verified by full-working-condition finite element fatigue simulation and mechanical stress test, the overall structure features ultra-high rigidity and deformation resistance, capable of coping with long-term peak load operation and frequent tripping operations in ultra-deep wells without structural fatigue damage.

Full-sealed High-end Intelligent Control System

Configured with dust-proof, heat-insulated and corrosion-resistant integrated control cabin, integrating full-process drilling data real-time acquisition, intelligent parameter self-optimization, multi-layer electromechanical safety interlock and full-function fault early warning & diagnosis. It realizes indoor automated intelligent operation, minimizing manual intervention and operational risks in long-cycle ultra-deep drilling.

Full-scene Extreme Environment Adaptability

The whole machine undergoes professional sand-proof, dust-proof, high-temperature heat insulation and low-temperature anti-brittle reinforcement treatment. Core electrical and hydraulic components adopt high-grade extreme weather resistant materials, supporting stable continuous operation in desert high-temperature, plateau low-temperature, windy and dusty harsh oilfield environments.
