Abstract:The air chamber structure and the work principle of air hammer are introduced,two key points of air hammer which are the energy storage of third air chamber and piston and energy liberation of first air chamber to bottom hole are proposed;From the three aspects which are the air chambers design parameters,the drill bit liner and the gap between components in air chambers,the operating performance of air hammers used in foam drilling is analyzed and also the possible processing plans in oil field to guarantee air hammers' normal operating performance are proposed.All of these can be helpful in foam drilling used air hammers in oil field.
Keywords:air hammer  air hammer drilling  KQC series of air hammers  foam drilling  mist drilling
