The T2 Series Core Barrel  drilling tool effectively contains the relevant provisions of the drill pipe, casing, core tube inner and outer tube and steel alloy composition pipe physical properties of diamond core drilling. Combine carbide, composite and diamond drills into a series that harmonizes wireline coring drilling and diamond drilling caliber.

The T2 Series Core Barrel drilling tools will have certain forward-looking aspects in terms of their technologies and applications. To a certain extent, this is conducive to promoting the promotion and application of new drilling techniques, new methods, new products, and new processes. During the process, a full study of international standards and foreign advanced standards was conducted.

The connection strength of the T2 Series Core Barrel drilling tool is effective to ensure that the drill tool has a good working performance in the hole. The connection method of the drill pipe and the joint is: 1 threaded connection; 2 plasma arc welding 3 friction welding.


In order to effectively improve the wear resistance of the surface of the product, the T2 series core barrel drills will effectively adopt surface heat treatment, chrome plating, and external surface welding of joints and tungsten carbide wear on the drill pipe, especially on the joints and thread surfaces. Layers and other methods can greatly extend the service life of the drill pipe.

In order to reduce the weight of the entire drill string, T2 Series Core Barrel drills have developed aluminum-magnesium-zirconium or aluminum-titanium alloy drill pipes connected with steel joints in petroleum, natural gas and geological core drilling. The T2 series core barrel drilling tools are used according to their uses: geological drilling tools, Dongying drilling tools, non-excavation drilling tools, engineering drilling tools, rotary drilling tools, mining drilling tools, mining drilling tools, screw drilling tools, and eccentric drilling tools.
