Land Mechanical Drilling Rig ZJ40J

The Land Mechanical Drilling Rig ZJ40J is a mature and reliable 4000m-class pure mechanical transmission land drilling rig, designed and manufactured in.

Product overview

The Land Mechanical Drilling Rig ZJ40J is a mature and reliable 4000m-class pure mechanical transmission land drilling rig, designed and manufactured in strict accordance with API 4F, API 7K and ISO9001 international industry standards. Developed for 3000-4000m medium-deep conventional oil and gas wells, tight gas, coalbed methane and medium-depth geothermal well drilling and completion operations, this rig adopts a classic all-mechanical drive configuration with ultra-high operational stability and strong formation adaptability. Featuring standardized skid-mounted modular structure, reasonable power matching and simple mechanical control logic, it delivers powerful and consistent torque output for complex medium-deep stratigraphic drilling. With low failure rate, convenient field maintenance and high cost-performance, the ZJ40J rig has become the most widely used mainstream drilling equipment for medium-deep onshore oilfield development, regional energy exploration and large-scale conventional well EPC projects worldwide.

Core innovative advantages and structural features

Mature Full-mechanical Transmission System

Equipped with industrial-grade pure mechanical transmission chain driven by high-power diesel engine cluster. The system features strong impact resistance, stable power output and zero electromagnetic interference, perfectly adapting to remote oilfield areas with unstable power supply and complex variable-load drilling conditions. It ensures long-term continuous and reliable operation with fewer electronic failure points and higher field environmental tolerance.

Standard Containerized Modular Skid Design

The whole machine adopts split standardized skid modules including derrick assembly, box substructure, main drawworks power unit and independent sealed control cabin. All module dimensions comply with international container transportation standards, supporting segmented containerized shipping and rapid on-site splicing assembly. It effectively reduces cross-border logistics costs and shortens rig-up and commissioning cycle for global project deployment.

High-rigidity Fatigue-resistant Derrick Structure

Adopts upgraded heavy-duty K-type open-front derrick with high-strength alloy steel material. Verified by full-working-condition finite element stress and fatigue simulation, the derrick maintains excellent overall rigidity, anti-deformation and wind-resistant performance under long-term 4000m medium-deep well heavy-load cyclic drilling, fully meeting high-intensity continuous construction requirements.

Low Operation & Maintenance Cost

Intuitive mechanical operation logic simplifies field debugging and daily operation procedures. All vulnerable parts adopt universal international oilfield standard specifications with mature global spare parts supply channels. The simple and reliable system structure greatly reduces daily maintenance difficulty, downtime loss and long-term comprehensive operation costs.

Wide-range Harsh Environment Adaptability

Key load-bearing steel structures adopt multi-layer weather-resistant anti-corrosion treatment; core mechanical moving parts are optimized with dust-proof, wear-resistant and high/low temperature resistant configurations. The whole machine can operate stably all year round in plains, hills, Gobi deserts and other conventional oilfield environments, adapting to high-temperature, windy, dusty and dry working conditions.
