Land SCR DC Drilling Rig ZJ80D

The Land SCR DC Drilling Rig ZJ80D is a super heavy-duty skid-mounted SCR DC electric drilling rig, independently developed for 6000-8000m ultra-deep.

Product overview

The Land SCR DC Drilling Rig ZJ80D is a super heavy-duty skid-mounted SCR DC electric drilling rig, independently developed for 6000-8000m ultra-deep well drilling, completion and complex downhole treatment operations. Strictly compliant with API-4F, API-7K and ISO9001 global industry standards, the rig adopts mature and upgraded SCR silicon controlled rectifier DC drive technology, featuring ultra-high torque reserve, stable low-speed output and strong complex formation adaptability. The whole machine adopts fully modular skid split design, supporting standard containerized multimodal transportation and rapid on-site assembly and commissioning. As a high-end ultra-deep well core equipment, it is widely used for ultra-deep conventional oil and gas, pre-salt reservoir resources, deep tight oil and shale gas large-scale block development, and is the preferred stable model for domestic and international ultra-deep oilfield key engineering projects.

Core innovative advantages and structural features

Upgraded High-power SCR DC Drive System

Equipped with enhanced high-capacity SCR rectification and DC speed regulation system. The main drawworks and rotary table adopt high-power independent DC motor drive, realizing stepless speed regulation and constant ultra-high torque output. The system features simple and reliable control logic, strong anti-fluctuation ability for complex power grids, and stable output under ultra-deep well high-pressure and variable-load working conditions, effectively avoiding drilling sticking and vibration problems.

Standard Containerized Modular Skid Structure

Super-large derrick, heavy-duty box substructure, high-power drawworks unit, SCR power distribution system and sealed intelligent control cabin all adopt independent skid modular design. The optimized overall dimensions fully conform to international container transportation standards, greatly reducing cross-border transportation costs and shortening the on-site rig-up and debugging cycle for overseas ultra-deep well projects.

Ultra-high-rigidity Anti-fatigue Bearing Structure

Adopts customized super-heavy K-type open-front derrick and reinforced thickened box substructure. After full-working-condition finite element fatigue analysis and mechanical stress verification, the overall structure has excellent structural rigidity, impact resistance and deformation resistance, which can cope with long-term peak load operation and frequent tripping operations of 8000m ultra-deep wells without structural fatigue damage.

Integrated Intelligent PLC Central Control System

Configured with fully sealed dust-proof, heat-insulated and corrosion-resistant driller control cabin. It integrates full-process drilling parameter real-time collection, precise load and speed control, multi-layer electromechanical safety interlock and intelligent fault self-diagnosis functions. Indoor centralized intelligent operation reduces manual intervention, effectively improving construction safety and operational efficiency of ultra-deep complex wells.

Extreme Environment Adaptability & Low Maintenance Cost

The classic upgraded SCR DC system has stable performance, low failure rate and long service life. Key components are treated with low-temperature anti-brittle, high-temperature anti-aging and salt spray anti-corrosion processes. Universal international standard wearing parts support rapid global after-sales maintenance and on-site replacement, adapting to long-cycle continuous operation in various harsh oilfield environments.
