Gas lift rig system Reverse circulation Drilling Machine

A Gas Lift Rig System  Air-Operated Circulation Drill ，is a drilling equipment ,suitable for Geothermal Drilling,that uses gas lift technology to circulate drilling fluid during drilling.  The system uses gas injection into the drilling fluid to create a reverse circulation, allowing fluid to flow from the bottom of  the wellbore to the surface. The gas lift rig system consists of several parts, including gas injection system, drilling fluid circulation system and  control system. The gas injection system usually includes a gas compressor, a gas injection valve and a gas lift cylinder.  The compressor provides high pressure gas, which is injected into the drilling fluid through the gas lift valve and the core barrel. The drilling fluid circulation system includes mud pump, drill string and drill bit. The mud pump pumps the drilling fluid down  the drill string and out through the bit. The gas injection creates a…
