Discipline: Drilling Engineering

 

Drilling coring tools
In the process of drilling using special coring tools to get the underground rock lumps to the ground up, the block rock called the core, through which you can determine the various properties of rock, intuitive study of underground structures and rock depositional environment , Understand the nature of the fluid and so on.


Coring bit: used to drill core
Outside the core tube: boring pressure, torque transmission
Core barrel: storage, protection of the core
