The ZJ90 6750DB full AC variable frequency land drilling rig is a super heavy duty ultra deep well drilling unit, developed for 7000 9000 m ultra deep on.
The ZJ90 6750DB full AC variable frequency land drilling rig is a super heavy duty ultra deep well drilling unit, developed for 7000 9000 m ultra deep on land drilling missions. Complying strictly with API 4F, API 7K and ISO9001 specifications, this rig is oriented toward ultra deep conventional oil gas, deep tight oil and shale gas exploration. It adopts high power full AC VFD independent drive and oversized high strength derrick substructure assembly, capable of enduring long duration peak hook load under high confining pressure complex deep formations. Mainly deployed in large scale ultra deep energy blocks in desert, Gobi and high altitude cold regions, it serves as key hardware for strategic deep earth resource exploration programs.
Drawworks, rotary table and main auxiliary units are driven by individual high power frequency converters. It delivers massive low speed torque, restricts drill string torsional vibration, and enhances tripping safety for ultra deep hole conditions.
Extra large K type open front derrick and heavy box shaped substructure are validated by multi working condition finite element fatigue simulation. The whole assembly maintains high structural rigidity under frequent maximum load tripping operations, resisting plastic deformation in long cycle ultra deep well jobs.
Major assemblies are split into standard container friendly modules for convenient sea land combined transportation. It shortens rig up and rig down period for cluster ultra deep well groups and lowers dependency on super large tonnage site cranes.
Sealed integrated control cabin realizes real time full item drilling parameter monitoring, automatic weight on bit regulation, multi layer mechanical electrical interlock protection and full process operation log recording, effectively cutting operational risks for long shift ultra deep drilling.
Core electric cabinets are reinforced with desert sand proof and high efficiency heat dissipation structure; key metal components adopt low temperature anti brittle material matching for high altitude frigid zones to support non stop year round field operation.
