The Land SCR DC Drilling Rig ZJ40D is a skid mounted land based SCR DC electric drilling rig, specially designed for 3000-4000 m medium deep well.
The Land SCR DC Drilling Rig ZJ40D is a skid mounted land based SCR DC electric drilling rig, specially designed for 3000-4000 m medium deep well drilling and completion operations. Manufactured in compliance with API 4F, API 7K and ISO9001 international standards, the rig adopts classic SCR silicon controlled rectifier DC drive technology, featuring stable power output, high torque reserve and strong anti interference capability. With modular skid split structure, it supports containerized sea land multimodal transportation and standardized on site assembly. This model is widely applicable for conventional oil and gas, coalbed methane, tight gas and medium deep geothermal well drilling, and is highly favored for overseas medium deep oilfield development projects with mature and reliable DC electric drive technology.
Adopts SCR rectification DC speed regulation technology. The drawworks and rotary table are driven by DC motors, delivering constant high torque at low speed and stepless speed regulation. It features strong load adaptability, stable drilling parameter output and outstanding resistance to grid voltage fluctuation, perfectly fitting complex medium deep formation drilling conditions.
Derrick, box type substructure, main drawworks, SCR power cabinet and integrated control cabin are arranged in independent skid modules. The split size matches international container transportation standards, greatly reducing cross border logistics costs and shortening on site rigging up cycle.
Equipped with reliable K type open front derrick and heavy duty box substructure. Verified by finite element mechanical analysis, the whole bearing structure maintains excellent rigidity and stability under long term cyclic load operation, effectively avoiding structural fatigue deformation during continuous medium deep well drilling.
Adopts centralized driller control room with unified electric, hydraulic and pneumatic control logic. It realizes full process drilling parameter monitoring, logic interlock protection, data storage and remote transmission, improving operation accuracy and field safety management level.
Classic DC drive structure with fewer vulnerable parts and lower failure rate compared with traditional mechanical rigs. Standardized international general accessories and simple system architecture facilitate daily maintenance and global after sales support.
