High-reliability Pure Mechanical Transmission System
Adopts mature industrial-grade full mechanical transmission scheme with diesel centralized power output, featuring strong anti-interference performance, stable high torque output and excellent overload resistance. It operates independently without external power supply, fully adapting to remote off-grid oilfields and wild construction sites. With fewer vulnerable electronic and hydraulic components, the system achieves ultra-low failure rate and long-term continuous heavy-load operation stability, perfectly meeting cyclic drilling and workover demands of 3000m medium-deep wells.
L-J Lightweight Compact Upgrade Structure
On the premise of retaining standard 3000m drilling depth and heavy-load bearing capacity, the whole machine undergoes targeted lightweight optimization. The derrick, box-type substructure and power skid adopt streamlined compact layout, effectively reducing overall dead weight and outer dimension. It greatly improves transportation flexibility for mountain roads, narrow passages and limited traffic conditions, realizing efficient cross-site migration compared with traditional ordinary ZJ30 rigs.
Modular Skid Fast Deployment Design
All core functional units adopt integrated standardized skid modular configuration with precise positioning and quick locking connecting structures. The rig requires no complex on-site calibration and foundation treatment procedures, realizing rapid assembly, splicing and commissioning. It significantly shortens rig-up cycle and project startup time, supporting frequent cross-well and cross-region turnover operations for batch well group projects.
Enhanced Medium-deep Well Drilling Performance
Equipped with upgraded reinforced K-type derrick and high-stability hoisting system, with optimized power matching and lifting torque. It delivers stronger rock-breaking capacity and drilling stability for medium-hard rock and complex composite stratums, effectively reducing drilling deviation and hole collapse risks during 3000m medium-deep well construction, ensuring high-efficiency and high-quality well forming.
Low Operation & Maintenance Threshold
Features intuitive mechanical gear shifting and centralized integrated control system with simple operation logic and low operator learning cost. All wearing parts adopt international universal standard specifications with complete global supply channels. The simplified and robust mechanical structure greatly reduces daily maintenance difficulty, downtime loss and long-term spare parts reserve cost.
Strong Full-condition Environmental Adaptability
Key load-bearing steel components adopt multi-layer weather-resistant, wear-resistant and anti-corrosion treatment. Core transmission and moving parts are equipped with dust-proof, sand-proof and wide-temperature adaptive structures. The whole machine can operate stably in plains, hills, Gobi deserts and arid mountainous areas, adapting to high-temperature dry, windy dusty and low-temperature cold field working environments.
Superior Comprehensive Cost Performance
Compared with variable frequency and hydraulic drilling rigs, the full mechanical structure has lower procurement cost and no complex later-stage system maintenance. The lightweight reusable modular design improves equipment utilization rate, effectively reducing comprehensive investment for medium-depth medium-scale drilling projects.
