The Land Mechanical Drilling Rig ZJ30J is a mature and reliable 3000m-class mechanical transmission land drilling rig, manufactured strictly in accordance with API 4F, API 7K and ISO9001 international industry standards.
The Land Mechanical Drilling Rig ZJ30J is a mature and reliable 3000m-class mechanical transmission land drilling rig, manufactured strictly in accordance with API 4F, API 7K and ISO9001 international industry standards. Designed for 2000-3000m medium-shallow conventional oil and gas wells, coalbed methane, tight gas, geothermal wells and industrial water well drilling and completion operations, this rig adopts a classic pure mechanical drive scheme with stable performance, low failure rate and extremely high field adaptability. Featuring standard skid modular layout, simple structure, convenient installation and easy maintenance, it is the most cost-effective and widely applicable core drilling equipment for onshore conventional oilfield development, scattered well group construction and medium and small energy EPC projects worldwide.
Equipped with mature industrial-grade mechanical transmission chain, matched with diesel engine centralized power output. The system features strong impact resistance, stable torque output and no electromagnetic interference. It is highly adaptable to unstable field power supply and complex variable-load drilling conditions, ensuring continuous and reliable operation in remote oilfield blocks.
The whole machine adopts standardized split-skid modular design, including derrick, substructure, drawworks power unit and independent control cabin. Each module conforms to international container transportation specifications, realizing segmented transportation and fast on-site assembly. It effectively reduces logistics cost and shortens rig-up cycle for cross-region project deployment.
Adopts optimized high-strength alloy K-type derrick structure, verified by finite element mechanical analysis. The derrick features light weight, high structural rigidity and excellent anti-fatigue performance, fully meeting long-cycle continuous drilling requirements of 3000m medium-shallow wells with stable lifting and rotary bearing capacity.
Mechanical control logic is intuitive and reliable with fewer electronic components and low failure probability. Wearing parts adopt universal international oilfield standard specifications, with mature global spare parts supply channels. The whole machine has low daily operation and maintenance thresholds, greatly reducing long-term comprehensive project costs.
Key structural components adopt weather-resistant anti-corrosion treatment; core mechanical parts are optimized for dust-proof, anti-aging and wide-temperature operation. The rig can operate stably in plains, hills, Gobi and desert conventional oilfield environments, adapting to high-temperature, windy and dusty working conditions all year round.

For operators running the same power plant across a whole field, spare-parts commonality and familiar controls matter as much as the rated hook. The ZJ30J is the mature 3000 m-class mechanical drilling rig built around that logic: 3000 m nominal depth on 114 mm pipe, a 1700 kN static hook, a 560 kW (750 HP) drawworks and a ZP275 rotary table, all behind a classic drive chain of diesels, clutches and chain. Where a new AC VFD or SCR electric rig would force crew retraining and a new spares shelf, this standard skid land drilling rig reuses the maintenance habits already established on the lease - which is why it remains the default for cost-sensitive small oilfield development and EPC work. The open-front mast and split skids are export-crated for cross-border projects.
A ZJ30J inquiry should state which drive architecture your existing fleet already uses and how the pumps and solids-control system are planned: the unit is quoted as a drawworks-and-mast package or as a full drilling line, and that choice changes both price and lead time. The 29 mm wireline on 5 x 6/10 lines and the 35 MPa standpipe rating are standard, as is the -30 C to +50 C envelope and the API 4F / 7K and ISO 9001 baseline. If your wells consistently run past 3000 m, the ZJ40J with its 2250 kN hook is the next step rather than an upgrade within this model.
We keep a configuration record for every rig we ship, so replacement parts are traceable years after delivery - a point that matters when a mechanical land drilling rig like this stays on a lease for a decade. Wearing parts follow universal oilfield specifications, and a written price offer follows within two days of your well design.
Optional low-temperature cold-resistant modification package for alpine regions; enhanced dust and sand-proof sealing system for desert and Gobi oilfields; salt spray anti-corrosion coating for coastal operation sites.
Support diesel engine brand customization and power matching adjustment to adapt to different regional fuel quality and construction intensity requirements.
Optimize single skid module size and weight distribution to meet container transportation and narrow well-site layout constraints.
Optional auxiliary hydraulic assist system and drilling parameter monitoring module to improve operation precision and intelligent level on the basis of mechanical main drive.
Custom equipment painting, brand logo marking, project-dedicated spare parts package and full-cycle after-sales technical support are available.
