This Core barrel system is particularly suitable for deep boreholes.

 The working system is noticeably different from conventional methods, but it is still a double tube drilling system.

 The fundamental difference is that the inner tube is lowered to the working position inside the drill string and is raised to the surface once it is full, by means of a fast acting cable. As the depth of the drill advances, drill rods are added without removing the core barrel.

 You just need to remove the drill string to change the core bit. Thus there is a significant increase in the useful time of drilling. Also conversion kits and spare parts.

 The core barrels are supplied without bit and without reamning, since depending on the formation to be drilled and the selected core barrel, the use of tungsten carbide, carbotec, diamond, tricone or threewing, will be recommended.

 

Roschen manufacture differenct types of the core barrels with high quality.
