Crawler Electric Drilling Rig SZJ1500EYL

The Crawler Electric Drilling Rig SZJ1500EYL is a low carbon, energy saving full electric crawler mounted deep well drilling rig complying with.

Product overview

The Crawler Electric Drilling Rig SZJ1500EYL is a low carbon, energy saving full electric crawler mounted deep well drilling rig complying with international petroleum and geothermal equipment standards. It is purpose built for 3500 meter deep geothermal well, coal bed methane, shallow on shore oil gas exploration and large capacity deep water well construction projects. Driven by explosion proof main motor power system, this rig eliminates high fuel consumption and exhaust emission of traditional diesel driven units. It is equipped with heavy duty self propelled crawler undercarriage, two speed electric top drive assembly, high rigidity telescopic mast and integrated intelligent control cabin. It supports mud rotary drilling, DTH air percussion drilling, foam drilling and reverse circulation drilling processes, delivering stable performance in sand gravel strata, weathered rock, medium hard and hard rock formations. The crawler chassis enables free travel over mountainous, muddy, desert and road less well sites without additional transport vehicles. Multi point synchronous hydraulic leveling outriggers guarantee stable heavy load deep hole operation. Built in real time drilling parameter monitoring and automatic weight on bit control module reduce manual intervention. As a low emission mobile drilling solution, SZJ1500EYL is well suited for environmental restricted areas and large scale new energy resource development projects for global drilling contractors.

Core innovative advantages and structural features

Full electric Low carbon Drive System

Adopts high efficiency explosion proof main drive motor, cutting comprehensive energy consumption by more than 50% compared with equivalent diesel powered drilling rigs. Lower operating noise and zero on site exhaust emission satisfy strict environmental protection requirements for geothermal and urban adjacent well site operations. Stable electric power output avoids power fluctuation caused by diesel engine wear under long time continuous heavy load drilling.

Heavy duty All terrain Reinforced Crawler Chassis

Optimized wide track shoe structure reduces ground pressure for anti sink performance in muddy and debris covered sites. It achieves outstanding grade ability to adapt to mountain slope, Gobi desert and complex off road conditions. Independent hydraulic travel motors support in situ steering and flexible on site relocation, eliminating dependence on haul truck equipment for scattered well locations.

Dual speed Electric Top drive Drilling Unit

Two stage switchable torque speed output matches variable formation conditions. Low gear mode supplies high torque for hard rock penetration; high gear mode provides high rotary speed to improve drilling efficiency for soft medium strata. Large bore spindle accepts heavy weight drill string for 3500 meter deep hole construction. Optimized electric motor thermal management system ensures non stop operation under sustained heavy load conditions.

Integrated Multi process Fluid Manifold Assembly

Factory pre integrated mud manifold, air manifold and foam pump unit are equipped as standard. Operators can switch between multiple drilling technologies directly on site without large scale pipeline modification, meeting diversified construction requirements for geothermal, coal bed methane and deep water well projects.

Intelligent Centralized Control & Multi layer Safety Interlock

Integrated control cabin visualizes hook load, torque, WOB, drilling depth and pressure data in real time. Automatic weight on bit control function lowers operator workload. Full range emergency stop linkage, mast hydraulic self lock, pipeline burst resistance protection and motor over temperature protection are embedded to enhance HSE performance for long term field operation.

Robust Structure & Convenient Field maintainable Layout

High rigidity telescopic mast bears 1500 kN maximum hook load. Key hydraulic, electric and wearing components adopt internationally universal specifications for convenient global spare parts supply. Modular component arrangement facilitates inspection and replacement under remote and harsh field working environments.
