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.
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.

For a 9000-12000 m ultra-deep programme, the hook load is the binding constraint before any other number. The ZJ120 9000DB full AC VFD land drilling rig is rated for a 9000 kN maximum static hook load, a 12000 m nominal depth on 114 mm drill pipe, and a 3000 kW main drawworks turning through a ZP705 rotary table. A super-large K-type open-front derrick and box substructure are fatigue-verified for repeated maximum-load cycles, while the decentralized frequency-conversion drive delivers enormous low-speed torque and suppresses drill-string vibration in pre-salt overburden, tight-oil and high-pressure deep formations. Its sealed control cabin runs closed-loop weight-on-bit control with multi-layer interlock and full operation-log storage across round-the-clock shifts — the kind of instrumentation that marks this flagship package for strategic deep-earth basins rather than a redeployed mid-depth machine.
When you request a ZJ120 9000DB drilling rig quotation, include the planned total depth and casing programme, expected formation pressure and bottom-hole temperature, the climate range at the basin, and your site electrical standard at 50 Hz or 60 Hz. The -45 C to +55 C working envelope and API 4F / API 7K / ISO 9001 certification are the certified baseline; GOST-grade power systems, zone-classified explosion-proof electricals, desert sand-sealing and low-temperature anti-brittle components are added per the specific basin rather than assumed.
Because the rig splits into container-compatible modules, every ZJ120 9000DB exported from our Jingzhou plant is shipped with the multimodal transport plan and the complete customs documentation package attached. The modular split structure cuts reliance on super-heavy lifting at remote well sites, and the export paperwork keeps the sea-and-land combined move from stalling at the border.
