Gas lift drilling equipment Drilling Machine

When these two technologies are combined, a gas-lift reverse circulation rig is formed. 

The system uses gas lift technology to strengthen the reverse circulation drilling process and improve the efficiency 

and effect of drilling operations.

Gas lift reverse circulation drill is usually composed of gas lift valve, gas lift mandrel, gas lift packer, 

gas lift line and gas lift manifold. These components work together to inject gas into the drilling fluid,

 reducing its density and promoting reverse circulation of drilling fluid and cuttings.
