Skid Mounted Split Modular Drilling Rig LS SK4500

The Skid Mounted Split Modular Drilling Rig LS SK4500 is a 4500m-class medium-deep split modular skid-mounted drilling rig, designed and manufactured in.

Product overview

The Skid Mounted Split Modular Drilling Rig LS SK4500 is a 4500m-class medium-deep split modular skid-mounted drilling rig, designed and manufactured in strict accordance with API 4F, API 7K and ISO9001 international industry standards. Specially optimized for limited-access well sites, mountainous areas, desert fringe zones and project sites with strict transportation restrictions, this rig adopts a full split skid modular design, breaking the size and weight limitations of integral drilling rigs. All core systems including derrick, substructure, drawworks, power unit and control system are divided into independent standard skid modules, realizing segmented container transportation and flexible hoisting assembly. Balancing 4500m medium-deep heavy-duty drilling capacity and ultra-high site adaptability, it is applicable for conventional oil and gas, tight gas, coalbed methane and medium-depth geothermal well projects, serving as the preferred cost-effective equipment for complex terrain medium-deep well development and international segmented transportation EPC projects.

Core innovative advantages and structural features

Full Split Modular Skid Design

The whole machine adopts scientific split modular layout, with each functional unit independently integrated on a standard skid base. All modules comply with international container transportation standards, solving the transportation difficulties of integral rigs in mountain roads, narrow passages and areas with overweight/over-limit restrictions. Each module features independent positioning and connecting structures, realizing fast on-site splicing and locking without complex calibration work.

Medium-deep Heavy-duty Drilling Capacity

Based on 4500m medium-deep well working condition optimization, the reinforced derrick and substructure assembly maintains high structural rigidity and load-bearing stability. It adapts to continuous heavy-load drilling, tripping and workover operations for complex medium-deep formations, with excellent anti-fatigue and wind-resistant performance, fully meeting long-cycle field construction requirements.

Flexible Assembly & Low Site Requirement

The split modular structure lowers requirements for well site flatness and integral foundation bearing capacity. The rig can be assembled in batches on narrow and irregular well pads, effectively reducing site leveling and foundation construction costs. It supports flexible disassembly and transfer after project completion, realizing repeated cross-well-site cyclic utilization.

Reliable Mechanical-Hydraulic Compound Drive

Equipped with mature mechanical-hydraulic compound transmission system, with stable power output and strong variable-load adaptability. The system features simple structure, low failure rate and convenient field maintenance, avoiding complex electronic system failures in harsh field environments. It delivers sufficient torque and lifting force for 4500m medium-deep well complex stratigraphic drilling.

High Adaptability for Harsh Working Conditions

All skid base and load-bearing steel structures adopt multi-layer weather-resistant and anti-corrosion treatment. Hydraulic, sealing and electrical components are equipped with dust-proof, sand-proof and wide-temperature protection modules, adapting to plains, hills, Gobi deserts and other complex terrains, stably operating in high-temperature, low-temperature and windy-dusty environments.

Low Comprehensive Operation Cost

Standardized modular configuration realizes universal interchangeability of wearing parts. The simple and reliable transmission and assembly structure greatly reduces daily maintenance difficulty and spare parts reserve cost. Reusable split modules effectively lower long-term project investment and equipment idle loss.
