6 FAQs about [Diagram of reverse circulation principle of engineering drilling rig]

How does reverse circulation drilling work?

SYSTEMS ‘Reverse Circulation’ drilling involves the supply of air down through the drill-string to decrease the ‘efective density’ of the water in the center of the drill-string. Operating much like an ‘air-lift’, the drilling spoils are carried out of the hole through this rising column lower-density air/ water mixture (see Figure below).

Can a reverse circulation drill be used with a rotary drill?

Reverse Circulation can be used in conjunction with rotary drilling bits as well as Down-the-Hole-Hammer applications. The Berminghammer Reverse Circulation Drills are particularly well suited to Down-the-Hole-Hammer applications due to their simple, rug-ged design and construction. Drill Depths up to 200’

Does filtration affect the performance of reverse circulation drilling operations?

The reverse circulation drilling method is now widely accepted as an effective way of exploration and grade control. However, the performance of reverse circulation drilling operations is greatly affected by the filtration effect (lost circulation) and no research has critically addressed this issue.

What is airlift reverse circulation drilling?

Using the air-lift reverse circulation drilling, combined with geothermal well construction project in Dalian, a good solution was presented to the hole wall's stab... in complex formation drilling, continuous core drilling, saving time and low labour intensity. It has become one of the major technical methods in large diameter wells drilling.

What is reverse circulation?

Reverse Circu-lation requires that the outer annular area of the casing be kept full of water in order to provide the hydraulic head required to efectively ‘push’ the central column of air/water/spoils up and out of the hole through the central pipe of the drill-string.

What is a Berminghammer reverse circulation drill?

The Berminghammer Reverse Circulation Drills are particularly well suited to Down-the-Hole-Hammer applications due to their simple, rug-ged design and construction. Drill Depths up to 200’ Used with both the BRC Drills and RC Swivel, Berminghammer’s drill string is the most durable and multi-versatile drill string in the industry.
