Reverse Circulation Drilling Machine 02

A reverse circulation drilling machine has gas lift rig sytem, is a drilling equipment of Air-Operated Circulation Drill that uses compressed air to lift drilling fluid (usually water or mud) out of the hole during drilling operations. This drilling method is commonly used in mineral exploration and geotechnical drilling.

A drill consists of a drill pipe, a drill bit, and a compressor that provides compressed air. The drill pipe is inserted into the hole, and the bit at the end of the drill pipe drills through the rock or soil. As the drilling proceeds, compressed air is injected into the drill pipe, creating a reverse circulation of the drilling fluid.

The drilling fluid, along with the cuttings from the drilling process, is raised to the surface through the annular space between the drill pipe and the shaft wall. The drilling fluid is then separated from the cuttings and recirculated back into the well while the cuttings are collected for analysis.

The advantages of using a gas lift reverse circulation rig include faster drilling speeds, better control of the drilling process, and the ability to drill in difficult formations. In addition, this method is less likely to cause damage to the well wall than other drilling techniques.
