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.
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.

At 3000-4000 m mid-deep wells, the question shifts from whether the rig can reach depth to whether it can hold together for the whole campaign. The ZJ40 2250DB full AC VFD land drilling rig is built for that durability: a 4000 m nominal depth on 114 mm pipe, a 2250 kN maximum static hook load, and an 800 kW main drawworks through a ZP375 rotary table. An upgraded high-strength K-type derrick and integrated box substructure pass finite-element fatigue analysis for long heavy-load shifts, and the independent VFD drives keep weight-on-bit controlled in hard tight-oil and shale-gas sections — the reason this model is a cost-effective mid-deep workhorse in desert, Gobi and plateau fields.
When you submit a ZJ40 2250DB drilling rig inquiry, provide the target depth and casing design, expected formation hardness and mud weight, ambient extremes, and your site power frequency. The -35 C to +55 C working envelope and API 4F / API 7K / ISO 9001 certification are the certified baseline; sand-proof, high-temperature and anti-aging packages are added for desert year-round operation, and the container-compatible modular split defines how the rig mobilizes between pads.
Factory acceptance testing can be arranged before shipment, so mid-deep contractors witness drawworks, rotary table and derrick performance on our Jingzhou floor before units are containerized. Once the rig is handed over, spare-parts support for the VFD drives, drawworks and hydraulic system continues through our supply channel, which keeps long 3000-4000 m campaigns from stalling over a single component.
Optional ultra-low temperature anti-fracture package, desert high-temperature heat insulation & dust-proof system, marine salt spray anti-corrosion coating and rainproof protection module.
Customizable 400V/50Hz, 480V/60Hz, Russian GOST voltage system and full explosion-proof electrical configuration for special hazardous areas.
Optional automatic feed drilling system, remote IoT monitoring, intelligent fault diagnosis and automatic pipe arrangement auxiliary system.
Modular size optimization for international container shipping and narrow mountain well-site construction.
Custom full-set solution including mud pump, solid control system, manifold system, dedicated spare parts package and customer brand logo customization.
