A drilling rig is an engineering machinery used for underground drilling operations and is widely used in construction, mining, petroleum, geological exploration, and other fields. According to different application scenarios and functional requirements, drilling rigs are mainly divided into the following types:

1. Geological exploration drilling rig
It is mainly used for geological exploration and mineral resource development. It can drill core samples at different depths to help understand underground geological structures and minerals, etc.

2. Engineering drilling rig
It is mainly used for construction, such as piling, foundation construction, and underground pipeline laying, such as rotary drilling rigs, down-the-hole drilling rigs, etc.

3. Water well drilling rig
water well drilling rig is mainly used to drill groundwater wells. It usually has a small borehole diameter and a moderate borehole depth.

4. Horizontal directional drilling rig
A horizontal directional drilling rig is a trenchless construction equipment that can drill horizontal holes underground for laying pipelines and cables.
Each drilling rig has its unique functions and application scenarios. If you don't know which one to choose, please feel free to contact Yugong to help you choose the right type and model.
