Hydraulic Core Drilling Rig 30 Meters Depth Geological Exploration Core Drilling Machine


Brief introductions of ST-30 hydraulic core drilling rig

ST-30 hydraulic core drilling rig is a small portable diesel oil drilling machine. It is mainly used for prospecting and exploration, geophysical exploration,drilling engineering such as road construction and blasting hole, shallow oil, natural gas and groundwater drilling. It also can be used for engineering drilling of dam grouting and tunnel ventilation and drainage. The drilling depth of ST-30 hydraulic core drilling rig is 30 meters. The open hole diameter is 89mm, and the final hole diameter is 75mm.

Features of ST-30 hydraulic core drilling rig

·Oil pressure automatic feeding mechanism, high drilling efficiency.
Using the upper ball clamp mechanism, non-stop re-chuck
Handles are centralized, easy to operate, safe and reliable.
Compact structure, small floor space.
The shell of drill rig and gearbox are made of aluminum. The shell reduce the weight of the fuselage.
Easy to decomposition and move, suitable for working in hilly terrain, mountainous areas and other complex terrain.


The drill bit is made of metal material.


Bit is the main component of drilling equipment, which is mainly used to break rock and form borehole. Rotary bits are commonly used in the oil industry at present. Driven by machinery, the rotary bits will rotate, which will drive the whole bit to produce centripetal movement. Through cutting and grinding, the rock will be cracked and broken, playing a role in drilling down.The bit is one of the main drilling equipment. The size and shape of the bit should be different according to the working environment and regional environment. When drilling oil, the bit should be selected reasonably and scientifically based on the specific needs and design plans
