Coring tool

Coring tools, drill to take rock core drilling tools used. In order to improve the rock mining rate and quality, different types and structures of coring tools, such as single tube, double tube and triple tube coring tools, local counter circular coring tools , Sometimes with special coring tools that take non-perturbed samples. The company is located in:

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

Take the definition of core
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.
 
Drilling coring tools advantages: 
 
Drilling coring tools
1. Coring bit: used to drill core;
2. Outside the core tube: boring pressure, torque transmission;
3. The inner core tube: storage, protection of the core;
4. Core pawl: cut off, support, remove the core;
5. There are hanging bearings, sub-water head, back pressure Versaili, centralizers and so on

Benefits:
 
• Transfer of power through core-barrel to core-head without losses due to buckling
• Higher torsion and tensile strengths than any alternative systems in the market place
• Stabilizers positioned at 20ft intervals improve hole gauge and concentricity
• ROSCHEN Tandem and Extended Tandem Assemblies promote increased success in high angled wells
