Overview

This document provides a detailed technical description and specifications of the XSC/XSL series deep (water) well drilling rigs. These rigs are designed for efficient drilling operations in various challenging environments such as hydrology wells, coalbed methane, shale gas, terrestrial heat, and coal-mine gas exploitation.

Product Introduction

• The XSC/XSL series rigs utilize full hydraulic control and a top drive system to rotate drilling tools, enhancing drilling efficiency.
• The rigs feature a tractor-mounted or full ground chassis for easy transportation and maneuverability on difficult roads.
• The top-mounted driving head has a large drift diameter, suitable for slurry drilling, air drilling, and air foam drilling across different terrain strata.

Technical Characteristics

• Compact overall structure allows operation in limited spaces and facilitates tunnel transportation.
• Two optional drive modes provide adaptability to various strata conditions.
• Extendable or box-type mast options support long casing drilling, improving work efficiency.
• Integrated visualized pressure feeding system accurately regulates drilling pressure based on depth.
• Four hydraulic supporting legs enable 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%.

Advanced Features

• Road condition adaptive all-terrain chassis with multi-axle steering and hydro-pneumatic suspension ensures excellent mobility on mud, sand, snow, and upland.
• 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 allows slow drilling and fast lifting, enhancing efficiency.
• Optional independent stem auto-change system enables full automation of stem loading/unloading, reducing labor intensity.
• Energy-efficient hydraulic control system with load sensitivity and proportional control ensures smooth, accurate, and shock-free operation.
• Large torque fastening/unfastening device works with power slip for rapid drill tool changes without extra labor.
• Comfortable closed cab design reduces noise and dust, improving operator environment with ergonomically designed controls.
