In the study of the structure and working principle of the hydraulic oscillator based on hydraulic pressure, design of pressure/screw speed test program of the oscillator was proposed. The entrance and exit of the pressure pulse test were completed under the different flow of different diameter of valve and matched dynamic valve of the hydraulic oscillators at the field. Through the spectrum analysis and the correlation analysis of the test data, the change rule of valve opening change frequency, pressure drop along wtih the valve port diameter was summerized up. The test results of fixed and dynamic valve selection have guiding significance, which provide technical data support for the optimization of structure and parameters design of hydraulic oscillator.
