Full-circle drilling rig airt lift drilling machine

 Gas lift reverse circulation drilling RIGS have the following advantages: First, it can reduce the amount of drilling fluid used and save costs. Second, because there is no need for circulating pumps to provide power, gas-lift reverse circulation RIGS are easier to operate and less expensive to maintain. In addition, since the gas-lift reverse circulation rig does not use hydraulic systems, it also reduces the risk of environmental pollution.
However, gas-lift reverse circulation RIGS also have some limitations. First, due to the small density of the gas, its ability to carry cuttings is relatively weak, so in some special geological conditions may not meet the needs of drilling. Secondly, because the gas lift reverse circulation drill requires a high-pressure gas source, it may not be able to meet the supply requirements of the gas source in some areas.
