| Abstract:Alternative process air drilling has many advantages, which has been applied in water well and geothermal well for years and now has become hot application in coal mine gas discharge well, coal bed methane well, oil & gas well, solar energy well and all types of large diameter borehole engineering. Practice shows that pneumatic DTH hammer and air lift reverse circulation are most popular. The paper introduced the pneumatic DTH hammer and air lift reverse circulation drilling technology in their development situation, working principle, operation points and the application attentions. |
