| Abstract: | In order to meet the needs of the deep expansion of oil and gas exploration and development,a great deal attention has been paid to the petroleum hydraulic percussive-rodary drilling technique taking as a high effective method for drilling hard formation by domestic and foreign scientific research personnel.It is the key of popularizing such a technique on a large scale to design and make an impactor with excellent performance.Through analyzing the working conditions of the impactor,establishing and verifying the dynamic model of percussive paramters,a suit of design methods of the percussive parameters are proposed in the paper,which provides a reliable basis for designing and improving the impactor in production units. |
