The Land AC VFD Drilling Rig ZJ70DB is a heavy duty skid mounted full AC variable frequency land drilling rig, specially developed for 5000-7000 m.
The Land AC VFD Drilling Rig ZJ70DB is a heavy duty skid mounted full AC variable frequency land drilling rig, specially developed for 5000-7000 m ultra-deep well drilling and completion operations. Fully compliant with API-4F, API-7K and ISO9001 international quality and safety standards, the entire rig adopts independent modular skid split structure, enabling standardized container transportation and efficient on-site assembly. This model is mainly used for large-scale deep conventional oil and gas reservoirs, deep tight oil, shale gas and ultra-deep geothermal well development. Featuring super heavy-load bearing capacity and long-cycle stable operation performance, it is core intelligent drilling equipment for large domestic and overseas ultra-deep oilfield block projects.
All core components including derrick, integral substructure, main drawworks, power unit and control cabin are designed with independent skid modules. The split structure perfectly adapts to international container sea and land combined transportation, greatly improving overseas project deployment efficiency.
The drawworks, rotary table and mud pump are equipped with separate high-power variable frequency drive motors. It achieves stepless speed regulation and ultra-precise drilling parameter control, effectively suppressing drilling string vibration in ultra-deep complex formations and improving overall drilling safety and efficiency.
Adopts upgraded large K-type front-opening derrick and heavy box-type substructure. Verified by multi-working condition finite element fatigue analysis, the whole structure maintains high rigidity and stability under long-term ultra-deep well heavy-load operation, avoiding structural deformation and fatigue damage.
Equipped with a fully sealed dust-proof and heat-insulated control cabin, integrating full-process drilling data acquisition, automatic parameter adjustment, multi-level electrical and mechanical safety interlock and fault self-diagnosis functions. It realizes indoor intelligent operation and effectively reduces manual operation risks.
The whole machine is treated with enhanced sand-proof, dust-proof, anti-corrosion and low-temperature anti-brittle processes. Key wearing parts adopt universal international oilfield specifications, supporting rapid maintenance and spare parts replacement in global complex well sites.
