This category of products is intended for use in wireline core barrel assemblies that are used in mineral exploration applications. Their purpose is to assist in minimizing the degree of drill hole angular deviation in target or deep hole drilling situations. The increased stability that these products provide will result in less vibration, a straighter drill hole and better core recovery. The types of stabilizing tools for wireline core drilling that are offered by Dimatec include:

• Stabilized Adapter Couplings and Locking Couplings
These tools are used in place of conventional blank or plasma spray coated adapter couplings and locking couplings. These tools are used to provide stabilization to the back-end of the core barrel assembly.

• Wireline Drill Rod Stabilizers
These tools are short stabilized couplings that are installed between the lengths of wireline rod in a drill string at set intervals. They are commonly used to control the whipping effect that may occur when using a standard size of drill rod in an intentionally oversized drill hole. The stabilizer element occupies the annular space between the drill pipe and hole wall. These tools are also used in deep horizontal holes to control the sagging effect of a long drill string.

• Stabilized Core Barrels (Outer Tubes)
These tools are used in place of conventional blank core barrels (outer tubes) or all-steel, fluted core barrels (outer tubes). When used in conjunction with a stabilized adapter coupling and stabilized locking coupling, a stabilized outer tube adds considerable rigidity to the core barrel assembly by limiting the amount of potential flexing that can occur between the bit and core barrel back-end, particularly under higher bit loads. An advantage of these stabilized outer tubes is that they have an inherently lower degree of fluid passage restriction between the stabilizing elements and the hole wall than do all-steel fluted outer tubes. This allows the fluid and cuttings from the bit and reaming shell to be ejected freely and results in less wear on their steel tool bodies.

All of these tools are manufactured with a full matrix body stabilizer ring that is cast onto the steel tool body for maximum bond strength and tool integrity. In addition, these stabilizer rings feature spiral waterway canals that both effectively clear the bit cuttings and provide full 360° hole contact with the matrix body stabilizer ring.

These tools are intended to stabilize and not cut. Therefore, they are purposely not set with any natural or synthetic diamond materials. The stabilizer rings on all of these tools are set with angular-shaped tungsten-carbide particles that are embedded into a tough, abrasion resistant matrix body. In addition, the set diameters of all of these tools are slightly smaller than that of the companion reaming shell but are slightly larger than that of the companion core bit.
