摘要

 
    

Air downhole hammer drilling has played important role in well construction for drought resistance in the mountainous area of western Henan Province, where is a bed rock area seriously short of water. This paper introduced the practical application, the operation points and the advantages of the technology in well construction. Further discussion and summary were made on the application effects of air downhole hammer drilling technology in fault fracture zone and well developed formation.
