150m XY-1A Hard Rock Drilling Rigs For Geotechnical Industry

The rated drilling depth is 150m, the maximum opening diameter is allowed to be 130mm (or within 500mm), and the final hole diameter is 150mm. This small drill rig is widely used in drilling family wells, drilling industry wells, drilling survey geological sampling, SPT service, and more. Drilling diameter ranges from 50-150mm or larger according to client requirements.

• Can meet the demand for various high efficiency drilling process needs, such as diamond wireline coring, impact drilling, directional drilling, reverse circulation continuous coring (sampling)
• Strong power, strong torque, strong bearing capacity, convenient to solve different downhole accidents
• Compact mechanical transmission structure, light weight, large diameter of spindle bore, hydraulic stabilizer legs, good rigidity

• Geological survey and exploration
• Geophysical exploration
• Foundation survey of roads and high-rise buildings
• Drilling works such as water wells and holes

After the bit has been working underground for a certain time, the blade diameter of the scraper bit becomes smaller, shorter and blunt, and the ability to break rock will become weaker and the progress will slow down. Due to tooth abrasion, erosion and bearing damage, the cone bit will not rotate flexibly or the cone will be stuck, which will increase the torque. If it is not lifted out in time, the cone accident will occur. Because of the heterogeneity of the formation, the diamond composite chips on the diamond bit are cracked, broken and dropped, which also slows down the drilling footage. In order to speed up the drilling of the whole well, it is necessary to replace the old bit in time. The bit is hundreds to thousands of meters underground.
