Introduction and Product Overview

The document presents technical information on the XSC/XSL series deep (water) well drilling rigs. These rigs utilize full hydraulic control and a top drive system to achieve high drilling efficiency. They are designed with a compact structure and flexible chassis options (tractor-mounted or full ground chassis) to ensure good maneuverability, even on difficult roads. The rigs are suitable for various applications including hydrology well exploration, coalbed methane extraction, shallow shale gas drilling, terrestrial heat extraction, coal-mine gas exploitation, and salvage operations.

Key Features and Technical Characteristics

• Hydraulic and Top Drive System: The rigs use a full hydraulic control system with a top drive that drives the rotation of drilling tools, enhancing drilling efficiency and adaptability to different strata.
• Compact and Flexible Design: Small dimensions allow drilling in limited spaces and easy tunnel transportation. The rigs feature extendable or optional box-type masts for long casing drilling, improving operational efficiency.
• Pressure Feeding System: An integrated visualized pressure feeding system accurately regulates drilling pressure based on depth.
• Hydraulic Supporting Legs: Four hydraulic legs enable rapid horizontal adjustment and transportation without the need for cranes.
• Rotational Centralizer and Floating Spindle: These features provide extensive operating space and increase drill stem thread service life by 30%.
• Advanced Hydraulic Control: Load sensitivity control system optimizes flow and pressure for energy efficiency. Proportional control ensures smooth, shock-free operation with high accuracy.
• Stem Changing Mechanism: Optional automatic stem loading/unloading system reduces labor intensity and improves safety.
• Comfortable Operator Cab: Closed cab design reduces noise and dust, enhancing operator comfort and visibility.

Main Technical Specifications

The document includes detailed specifications for multiple models within the XSC/XSL series, highlighting parameters such as:

• Drilling depth capabilities ranging from approximately 300m to over 1000m depending on model.
