The ZJ120 9000DB full AC variable frequency land drilling rig is a super large ultra deep well drilling unit, designed for 9000 12000 m extreme ultra deep terrestrial drilling assignments. Fully compliant with API 4F, API 7K and ISO9001 quality specifications, this flagship rig is dedicated to ultra deep conventional oil gas, deep tight oil, pre salt formation exploration and earth science scientific drilling. Equipped with ultra high power full AC VFD drive system and extra large heavy duty derrick substructure assembly, it can sustain extreme hook load and cope with high pressure, high temperature complex subsurface formations. It represents top tier land drilling hardware for strategic deep earth resource exploration in global harsh condition basins.
Drawworks, rotary table and critical auxiliary devices adopt independent high capacity frequency converters. It delivers enormous low speed torque, suppresses severe drill string vibration, and greatly improves safety during tripping operations in ultra deep high stress formations.
Giant K type open front derrick and reinforced box type substructure undergo multi load case finite element fatigue verification. The whole structure maintains outstanding rigidity under repeated maximum hook load cycles, avoiding structural risk during long duration ultra deep well campaigns.
Major assemblies are divided into container compatible modules for efficient sea land multimodal transport. It optimizes rig up and rig down workflow for ultra deep cluster well groups and reduces reliance on super heavy lifting equipment at remote well sites.
Provides full range real time drilling parameter acquisition, closed loop automatic weight on bit control, multi layer interlock safety protection and complete operation log storage. It mitigates human error risks during extended ultra deep well shifts.
Core electrical cabins feature enhanced sand proof, dust sealing and high efficiency heat dissipation for desert basins; low temperature anti brittle alloy materials are adopted for key load bearing components to adapt to frigid high altitude field conditions.
