Product Description

Coal Mining PDC Impregnated Diamond Coring Bit PDC Coring Bit


 

Product Description

The PDC diamond coring bit is also called a hollow bit /  a thin tubular multi - toothed bit, the drill body is inlaid with carbide plates.

Core-taking aims to obtain complete stratigraphic decomposition data during exploration, development, and construction. Through core analysis and research to better formulate a reasonable development and construction program.
Use the core analysis data to understand the strength of different formations, such as drill ability and abrasiveness, to guide drilling operations and achieve better drilling efficiency.
The distribution of oil, gas, and water in the oil and gas is analyzed from the core sampling of the target formation, and the porosity permeability and the oil and gas saturation as well as the effective thickness of the oil and gas layers is calculated. Thus producing more valuable oil and gas fields.

Different labial shape matrix formulations are suitable for coring in complex rock formations, and the cores drilled will provide reliable data for geological and engineering studies. Classified according to the shape of PDC:Flat PDC core bit,Bread PDC core bit,Cut PDC core bit,Fan PDC core bit and Helmet  PDC core bit.
Guangzhou International Technology  Co.,Ltd. can design various types of PDC core bits according to customer requirements.
