Some ideas and suggestions are put forward according to the suitable conditions of hydro-percussive rotary drilling technology in geological drilling, drilling equipment configuration requirements, drilling fluid and field maintenance and new products development. It is believed that the current improvement of geological equipments and the strengthening of flushing fluid performance, quality and solid phase control (purification) are favorable to promote the application of hydro-percussive rotary drilling technology, small-diameter diamond wire-line core hydro-percussive rotary drilling technology has become the most widely used hydro-percussive rotary drilling technology. At the present , the revision of original geological and mineral standards “The regulations of hydro-percussive rotary drilling technology（DZ/T 0053—93）” is one of the good methods to promote the development of hydro-percussive rotary drilling technology in China. In the future, it is also necessary to strengthen the development and demonstration application of new type of high-energy hydro-hammer and attach great importance to the optimization of large diameter and hydraulic hammer non-coring drilling technology.
