Système de tubage à avancement

Un système de tubage à avancement est l’outil idéal pour progresser rapidement lors du forage dans des conditions de sol qui contiennent beaucoup de schiste, de sable ou qui ont une texture friable et beaucoup de morts-terrains.

 

Le système comprend trois parties : le tube extérieur, l’ensemble intérieur et le tube de chargement.

 

Les trois parties travaillent ensemble pour améliorer vos performances de forage dans les morts-terrains et sont fabriquées avec des matériaux de qualité pour une durée de vie plus longue.

Diamond drillers can fall into a routine of using the same equipment over and over. Why not? If it isn’t broken, don’t fix it. This is especially true if you are used to drilling in the same region where ground conditions may not vary all that much. However, you may then find yourself drilling in another part of the country, or the world, with conditions that require a different type of equipment.

In order to be able to get good drilling performance, diamond drillers should have a thorough understanding of their drilling equipment. They should be familiar with the individual pieces, their function and how they work together as part of the drilling process. The core barrel plays an important role as this is what you use to recover core. Today, most diamond drillers use wireline core barrels.

In an earlier blog, we looked at the core barrel assembly, this being 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 and effectively. We looked at the parts of the inner tube of which the head assembly is a part. It is a complex part so it is well worth looking at it in detail.
