35.2mm Core 46mm Hole Wireline Double Tube Core Barrel Drilling

35.2mm Core 46mm Hole Double Tube Core Barrels

Generally, there are three kinds of core barrel depending on the tube quantity of the core barrel.

Double Tube Core Barrels

TT Series Core Barrel
◆Ultra-thin wall double tube core barrels, available diameters 46 and 56 mm. Very thin cutting face allows very rapid penetration rate through hard formations. They are suitable for underground mining applications.
----T2 Series Double Tube Core Barrels
◆The T2 Series are thin wall double tube core barrels, used for surface exploration, especially mining applications. Due to their thin kerf, these core barrels provide rapid penetration. Available in diameters 36, 56, 66, 76, 86, 101mm.
----T6 Series Double Tube Core Barrels
◆These are a continuation of the T2 series, but of a sturdier design and available in larger diameters, 76, 86, 101, 116.131 and 146mm. They are applied in surface mining and geotechnical drilling.

----LTK Series Double Tube Core Barrels
◆The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective, high production, which is designed for optimum production and core recovery in medium to extra hard rock formations. Available sizes 48 and 60mm.
----WF Series Double Tube Core Barrels
◆They are geotechnical core barrels primarily designed for coring in relatively soft formations by using face-discharge bits. With simple construction they' re more resilient to damage than thin-wall barrels, but with slower penetration rate.
-WG Series Double Tube Core Barrels WG
◆There are double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H. WM Series Double Tube Core Barrel
◆WM series double tube core barrels was developed as a solution to the ever present problem of recovering a high percentage of core when drlling badly fractured or broken strata or soft and friable material that is easily eroded by the circulating fluid. Mud or water can be used with this core barrel while diling. It has more sturdy design compared to the metric series core barrels.
---- Wireline Double Tube Core Barrels
◆Wireline double core barrels are primarily used in deep coring. With an overshot device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved.
◆Chinese Standard Double Tube Core Barrels
◆Chinese Standard Wireline Double Tube Core Barrels
◆Jet-type Reverse Circulation Double Tube Core Barrel
