摘 要：Percussive-rotary drilling technology was considered many years ago as one of the best approaches for hard rock drilling. It is a key for popularizing this technology on a large scale to design and make an impactor with excellent performance. This paper presents a suit of method to design the percussive parameters for the oil or gas field by introducing the working principle of back-pressurod impactor, dividing the working periods of impaetor into three phases and establishing the computer emuiational model of percussive parameters. It draws a comparison between the results of model calenlation and experiment on the basis of analyzing the experiment results of impactor. The conclude provides credible foundation for designing and further ameliorating the impactor.
