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 fields such as hydrology, coalbed methane extraction, shale gas, terrestrial heat, coal-mine gas exploitation, and salvage work.

Product Introduction

• The XSC/XSL series rigs use full hydraulic control and a top drive system to rotate drilling tools, achieving high drilling efficiency.
• The rigs feature a tractor-mounted or full ground chassis for good maneuverability, adaptable to difficult terrains.
• The top-mounted driving head has a large drift diameter, suitable for slurry drilling, air drilling, and air foam drilling.
• Flexible design allows use in diverse geological strata and construction environments.

Technical Characteristics

• Compact overall structure suitable for limited space and tunnel transport.
• Two optional drive modes provide adaptability to different strata.
• Extendable or box-type mast options support long casing drilling, improving 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%.

XSC Series Specific Features

• Road condition adaptive all-terrain chassis with multi-axle steering and hydro-pneumatic suspension for severe road conditions (mud, sand, snow, 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 system allows slow drilling and fast lifting, enhancing performance and efficiency.
• Optional independent stem auto-change system enables full automatic stem loading/unloading, reducing labor intensity.
• Advanced hydraulic control system with load sensitivity control for energy efficiency and precise proportional control of movements.
• Large torque fastening/unfastening device works with power slip for rapid drill tool changes without worker assistance.
• Comfortable closed cab with noise and dust insulation and ergonomically designed operation platform.

Main Technical Specifications

The document includes detailed tables listing parameters such as drilling depth, maximum working floor diameter, lifting capacity, feeding capacity and speed, torque, spindle speed, engine power, winch capacities, breakout torque, mud and foam pump flow and pressure, chassis type, dimensions, weight, and other key performance indicators. Various models are compared, showing a range of capabilities from smaller rigs (e.g., XSC5/260) to large automobile chassis rigs (e.g., 1SC30/1200) with corresponding increases in power, capacity, and size.

Construction Cases

Several real-world applications of the XSC/XSL series rigs are listed, including:

• Coalbed methane (CBM) well construction in Shanxi province.
• Water well drilling and hydrological monitoring well construction in Shanghai, Bozhou, Yancheng, Henan, and Shanxi.
• Water-probing in mine construction.

Critical Information and Recommendations

• The product specifications may evolve with technological development; the sample information serves as a reference only.
• Supply conditions should comply with the sales contract.
• For the latest product information, direct contact with the manufacturer is recommended.

Summary

The XSC/XSL series deep well drilling rigs are advanced, versatile machines designed for efficient and adaptable drilling operations across a variety of challenging environments. Their hydraulic control systems, flexible chassis, and automated features reduce labor intensity and improve operational efficiency.
