The Land SCR DC Drilling Rig ZJ50D is a heavy duty skid mounted SCR DC electric land drilling rig, developed for 3500-5000m deep well drilling and completion operations. Complying fully with API 4F, API 7K and ISO9001 international quality and safety standards, this rig adopts mature and reliable silicon controlled rectifier (SCR) DC drive technology. It features stable low speed high torque output, strong grid fluctuation resistance and high operational stability. With modular split skid structure, the whole unit supports standardized containerized multimodal transportation and rapid on site assembly. Widely applied in deep conventional oil gas, tight oil, shale gas and deep geothermal well projects, it is a cost effective and highly reliable core drilling device for medium and large scale domestic and overseas deep oilfield block development.
Equipped with classic SCR rectification DC speed regulation system. The drawworks and rotary table adopt independent DC motor drive, realizing stepless speed regulation and constant high torque output. Compared with traditional mechanical rigs, it delivers more stable drilling parameters, stronger load impact resistance and lower failure rate, adapting perfectly to complex deep formation drilling conditions.
Core components including derrick, heavy duty box substructure, main drawworks, SCR power cabinet and integrated control cabin are divided into independent standardized skid modules. The optimized external dimensions fully meet international container shipping standards, greatly reducing cross border logistics costs and improving rig up efficiency for overseas projects.
Adopts large K type open front derrick and upgraded heavy load box substructure. Verified by multi working condition finite element fatigue analysis, the overall structure maintains excellent rigidity and deformation resistance under long term maximum hook load cyclic operation, ensuring structural safety and stability during high intensity deep well drilling.
Features a fully sealed integrated driller cabin, integrating full process drilling data real time acquisition, stepless speed regulation control, multi layer electrical safety interlock, fault self diagnosis and data storage functions. Indoor centralized operation effectively reduces manual errors and improves overall drilling safety and intelligence level.
The whole machine is optimized for long cycle continuous operation, with fewer vulnerable parts and simple system logic. Key accessories adopt universal international oilfield standards, supporting rapid on site maintenance and convenient global after sales spare parts supply.
