Overview

This document provides a detailed technical description and specifications of the XSC/XSL series deep (water) well drilling rigs. It includes product introduction, technical characteristics, main specifications, and examples of construction applications.

Product Introduction

• The XSC/XSL series are hydraulic-controlled deep well drilling rigs equipped with a top drive system for high drilling efficiency.
• They feature a compact and flexible design suitable for transportation on tractor-mounted or full ground chassis, enabling operation in difficult terrains.
• Applications include hydrology well exploration, coalbed methane extraction, shallow shale gas drilling, terrestrial heat, coal-mine gas exploitation, and salvage operations.
• The rigs support multiple drilling methods such as slurry drilling, air drilling, and air foam drilling, adaptable to various strata conditions.

Technical Characteristics

• Compact overall structure allows drilling in limited spaces and easy tunnel transportation.
• Two optional drive modes provide adaptability to different geological strata.
• Extendable or box-type mast options enable long casing drilling, improving efficiency.
• Integrated visualized pressure feeding system accurately regulates drilling pressure based on depth.
• Four hydraulic supporting legs allow rapid horizontal adjustment and transportation without cranes.
• Rotational centralizer offers extensive operating space.
• Optional external floating spindle increases drill stem thread service life by 30%.
• Road condition adaptive chassis with multi-axle steering and hydro-pneumatic suspension ensures excellent off-road mobility on mud, sand, snow, and upland terrains.
• Full hydraulic top-drive with floating output port reduces drill stem thread wear and supports reverse circulation construction.
• Feeding system with large stroke and cylinder-wire rope speed multiple feeding provides slow drilling and fast lifting modes for improved performance.
• Optional automatic stem changing mechanism reduces labor intensity by automating stem loading/unloading.
• Advanced hydraulic control system with load sensitivity and proportional control ensures energy efficiency, smooth operation, and precise speed adjustment.
• Large torque fastening/unfastening device enables rapid drill tool changes without additional labor.
• Comfortable enclosed cab with noise and dust insulation and ergonomically designed operation platform enhances operator environment.
