Overview of ST-350 Pneumatic Drilling Rig

ST-350 Pneumatic Drilling Rig Parameter:

2. Strong Formation Adaptability: Coping with Complex Geological Conditions in Medium-Deep Holes

• Unconsolidated Formations (Sand Layers, Gravel Layers): Equipped with scraper bits or auger bits with a diameter of Φ150-300mm, combined with a mud circulation system, the drilling speed (5-15r/min) is controlled by hydraulics to avoid "drill pipe sticking" in sand layers; mud wall protection can form a 5-10mm mud cake on the hole wall, preventing collapse of deep hole walls.
• Hard Formations (Moderately Weathered Rock): Replace with roller cone impact bits and activate the hydraulic impact mode (impact frequency 300-500 times per minute). Rock breaking is achieved through "low rotation speed + high impact force", while maintaining a large-displacement mud circulation to quickly discharge cuttings and avoid blunting of bits due to cuttings accumulation at the bottom of the hole.
• Special Formations (Salt-Bearing Layers, Clay Layers): Collapse-resistant drill pipes and anti-adhesion bits can be installed, combined with customized mud (e.g., salt inhibitors, lubricating additives) to reduce "bit balling" in clay layers and corrosion of drilling tools by salt-bearing layers, ensuring continuous drilling in deep holes.

3. Balanced Intelligence and Safety: Reducing Risks and Thresholds of Medium-Deep Hole Operations

• Intelligent Monitoring and Parameter Control: Most models are equipped with a touch screen to display real-time parameters such as drilling depth, torque, hydraulic pressure, and mud flow. Some intelligent models are equipped with a "formation identification algorithm", which can automatically adjust drilling speed and impact force according to torque changes (e.g., automatically increasing impact power when encountering hard rock, and automatically reducing speed when encountering unconsolidated formations), allowing even novice operators to work stably.
• Safety Protection System: Standardly equipped with "overload protection" (automatic shutdown when torque exceeds the limit), "drill pipe anti-drop device" (locked drill pipe joints + hole mouth anti-drop clips), and "hydraulic system explosion-proof valve" (preventing sudden sinking of the machine body due to oil pipe rupture). These functions avoid high-risk faults such as "drill pipe sticking" and "drill pipe dropping" in deep holes, reducing the difficulty and cost of rescue.
• Easy Operation: Equipped with an "automatic drill pipe handling device", eliminating the need for manual handling of heavy drill pipes (3-6 meters long). Only 2-3 people are required for a single shift operation, saving 50% of labor compared with traditional manual drill lifting. Some models support remote control, allowing monitoring of drilling operations 10-20 meters away to avoid risks such as mud splashing at the hole mouth and noise pollution.

4. Optimized Durability and Maintainability: Adapting to Long-Term Field Operations

Durable Core Components: Hydraulic pumps and motors use imported or domestic first-tier brands (e.g., Kawasaki, Huade), which can withstand high pressure and long-term operation; drill pipes are made of 45# seamless steel pipes, 经过 quenching and tempering treatment, with a tensile strength of ≥800MPa and a service life of 5000-8000 meters.

Convenient Maintenance: Key components (e.g., hydraulic filters, drill bits, mud pumps) are reserved with quick-disassembly interfaces. It only takes 2-4 hours to replace hydraulic oil and clean mud pipelines; the machine body is equipped with a fault diagnosis system, which indicates problems such as "insufficient hydraulic oil" and "clogged filter" through indicator lights or a display screen, allowing preliminary troubleshooting without professional personnel.

Strong Weather Resistance: The machine body adopts sandblasting derusting + electrostatic spraying technology, with a rust prevention grade of Sa2.5, and can operate stably in an environment of -20℃ to 45℃; the hydraulic system is equipped with an oil temperature control device (low-temperature preheating, high-temperature heat dissipation) to avoid faults caused by hydraulic oil solidification in winter and excessive oil temperature in summer.
