The ZJ50-3150DB full AC variable frequency drilling rig is a mainstream heavy-duty onshore drilling equipment widely adopted in global mid-deep and deep.
The ZJ50-3150DB full AC variable frequency drilling rig is a mainstream heavy-duty onshore drilling equipment widely adopted in global mid-deep and deep well projects. Manufactured strictly in accordance with API-4F, API-7K and ISO9001 international standards, this model is designed for 4000-5000 m deep well drilling. It is primarily applied in conventional deep oil & gas reservoirs, large-scale shale gas and tight oil block development. Adopting full digital AC-VFD independent drive and high-load structural design, the equipment features strong drilling stability, high intelligent level and excellent harsh environment resistance. It is the core preferred model for medium and large energy engineering contractors for long-cycle deep well exploitation.
The drawworks, rotary table and mud pump adopt independent frequency conversion control, achieving ultra-precise drilling parameter adjustment. It effectively solves drilling vibration and tool sticking problems in deep complex strata, improving drilling efficiency and wellbore integrity.
Equipped with upgraded large K-type front-opening derrick and high-rigidity box substructure. Verified by finite element fatigue simulation, the whole machine maintains stable bearing capacity under long-term deep-well heavy-load operation, adapting to hard rock and complex fault strata.
Overall split modular design matches international standard container transportation specifications. It greatly reduces on-site assembly and disassembly time, lowers construction costs, and improves well site turnover efficiency for batch cluster well projects.
Adopts industrial-grade PLC centralized control system with real-time drilling data monitoring, automatic weight-on-bit control, and multi-layer mechanical & electrical safety interlock. It greatly reduces manual operation intensity and field safety risks.
Enhanced overall sand-proof, dust-proof and high-temperature resistance for desert oilfields; optimized low-temperature brittle resistance and anti-aging technology for plateau and cold-region projects, supporting full-year continuous operation.
