How important wireline core barrels are?

Wireline core barrels have many advantages and can be used in so many ways. They play an important role in mineral exploration. They are also fully compatible with other corresponding systems and always have available spare parts .

What's wireline core barrel used for?

The core barrel plays an important role in diamond drilling because it is used to recover the core. Today, most diamond drillers use cable core drillers, which have become the standard for high-yield core recovery. To provide more convenience, they are fully compatible with other corresponding systems and spare parts are always available. But this is not the only application of wireline core barrel, through its special structure, it can provide a lot of application.

Design and operation of an extended core barrel.

The extended core barrel's (XCB) coring system is used in sedimentological, climate, and paleoceanographic studies. Extended core barrel is usually used when the formation becomes too hard for the piston core or when its hardness is not sufficient to allow the use of the rotary core barrel (RCB) for effective harvesting.

How to stabilize core barrel?

The core barrel assembly is the equipment that is used to recover core, and plays a very important role in the diamond drilling operation. The success of an operation depends on retrieving core efficiently,so it is well worth looking at it in detail.

What's features of impregnated diamond core bits?

The impregnated diamond core bit is synthesized from very small, high-quality diamond through a uniformly mixed metal matrix. Select the hardness of the matrix through the appropriate rock formation, so that it wears evenly throughout the life of the bit, revealing new sharp diamonds. Higher diamond concentrations will increase longevity and permeability.

What's coventional core barrels?

Cores are defined as cutting and removing cylindrical rock samples from a wellbore. Coring provides the operator with a relatively undamaged sample or cross section of the reservoir rock. By obtaining cores, geologists can study the porosity and permeability of underground rocks. Conventional coring and sidewall coring are the two most commonly used coring methods. Conventional coring uses a component called a "core barrel" that consists of a drill string that extends to the bottom of the hole. The core tube has a hollow inner tube, and the outer tube and drill string rotate around it and remain stationary. To reduce damage to the core, the operator can use a fiberglass cover or rubber cover. Special core drill is used for cutting. The hole surface of hollow drill has natural diamond or PDC cutting surface.

What's the advantage of wireline core barrel?

The wireline core barrel through its special structure, can provide a lot of application. It has the advantages of large diameter, high-quality core, ability to obtain good recovery in a wide range of geological formations and excellent hydraulics.

What are diamond drill bits?

Diamond drill bits are useful portable drills. They can drill clean holes in bricks, glass and concrete, and are better than other drills bits. The diameter of the hole you drill can be as small as 20 mm, as large as 130 mm, and as deep as 300 mm. They come in many varieties and types, with better performance and capabilities than their steel counterparts. It is important to know when and how to use the diamond drill bits.

Why are impregnated core bits more beneficial?

Impregnated core bit is the most commonly used drill in mineral exploration industry. The advantages of impregnated core bits over bits made from other cutting media include: versatility, Its simple geometry makes it less vulnerable to damage and easier to adapt to changes in geological structures or zones. So on some specific projects it is more beneficial.
