AAir-Operated Circulation Drill is a drilling equipment ,has High Torque Drilling Rig,that uses compressed gas to lift drilling fluid and cuttings out of the wellbore during drilling. Gas lift systems are used in reverse circulation drilling, where drilling fluid is pumped along the annulus into the drill pipe, carrying cuttings with it. The gas lift system injects compressed gas into the drilling fluid stream to create a low-pressure zone that lifts fluid and cuttings from the wellbore to the separator. The separated cuttings are then discharged and the drilling fluid is recycled back into the wellbore. This type of rig is commonly used in geothermal drilling, mineral exploration, and environmental drilling applications.
