Wire line core barrel T2 T6 series

Product description:

Advantages of Wire-line core barrel

 1. Save Time and manpower

No need to take every piece of the drill strings out to get the samples, saving a lot of time to hoist and disassemble the drill rods, by using wireline core barrel. And core barrel could be moved from the bottom of the hole without removing the drill rod string assembly.

In this process most of time is available for drilling and so speedier progress can be made with the same time spent when drilling.

2. Get larger core samples

For wireline drilling, the rods are made of fine high tensile steel. This makes them thin, so that the core can be as large as possible.

3. Making deep exploration

Wire line drilling is possible up to a depth of 1000m, or far more than that.

Wireline core barrel is a special type of core drilling, most commonly used for minerals exploration. Unlike some types of drilling, the aim of core drilling is not to dig a hole, but to retrieve a core sample-a long solid cylinder of rock that geologists can analyze to determine the composition of rock under the ground.

Wire-line core drilling tools can lift core from drill rods without picking up coring system.

A complete set of wire-line drill tools include:

1)    Core barrel assembly,

2)    overshot assembly,

3)    drill rods,

4)    wireline winch,

5)    hoisting plug,

6)    circular wrenches etc.

It has some advantages such as high penetration rate, higher core recovery ratio, long bit lifetime and lower labour. The advantages is obvious with the increasing of drill hole depth.
 
Our head assembly features long life span, good compatibility with parts like inner tube and outer tube from other vendors, and availability in all spare parts.

Diamond bits Crown Shape and Applications:

1.    Flat : Applicable to drilling different levels of hardness or abrasive formation, generally for single and dual tube drill bits

2.    Semi-round  : Good distribution of the diamond at bit face, adapt to a small broken or loose formation, applicable to drilling medium-hard and hard formation

3.    Ladder : Applicable to drilling medium -hard, broken or interbedded formations, hole deviation can be prevented

4.    Applicable to drilling medium -hard, have good stability during the drilling

5.     Bottom jetting : Bottom jetting applicable to drilling sedimentary or metamorphic formations which containing more power, high coring recovery rate and avoid excessive washout of core. We supply A-Gauge impregnated core bit:AQ, AW, AGM;
