The ZJ40-2250DB full AC variable frequency land drilling rig is a mature medium-heavy duty drilling unit tailored for 3000-4000 m mid-deep well.
The ZJ40-2250DB full AC variable frequency land drilling rig is a mature medium-heavy duty drilling unit tailored for 3000-4000 m mid-deep well construction. Designed and manufactured in strict accordance with API-4F, API-7K and ISO international specifications, this model is widely used for conventional oil/gas, tight oil and shale gas industrial development. Equipped with full digital VFD independent drive technology and heavy-load derrick structure, it delivers outstanding stability and safety for long-cycle continuous drilling. Optimized for desert, Gobi, plateau and windy field conditions, this rig is one of the most cost-effective and reliable mid-deep drilling solutions for global onshore energy contractors.
Drawworks, rotary table and mud pump adopt separate variable frequency drive, achieving ultra-smooth speed regulation and precise drilling weight control. It effectively reduces drilling tool wear and improves overall wellbore quality for mid-deep formations.
Upgraded K-type high-strength derrick and integrated box substructure with finite element fatigue analysis. The whole machine resists deformation under long-term heavy-load operation and adapts to complex hard strata drilling.
Optimized block modular split design adapts to standard container transportation. It greatly reduces on-site assembly time, lowers reliance on large hoisting equipment, and improves field turnover efficiency.
Industrial PLC intelligent control platform integrates real-time data acquisition, automatic drilling control, and multi-level safety interlock protection. It minimizes human error and improves operational safety standards for long shifts.
Enhanced sand-proof, dust-proof and high-temperature resistant design for desert oilfields; standardized anti-aging and anti-corrosion treatment for all outdoor structural and electrical components, ensuring stable year-round operation.
