This paper introduces a new jet hydrodynamic vibration technique to dispose oil formation damage, and investigates the influences of main working parameters on the vibration generator's performances, including frequency, power and jet interval. It also presents a series of experimental tests in detail, analyses the vibration condition and state, and proposes a few significative suggestions. The experimental results and the field tests show that this kind of hydrodynamic vibration technique can improve the flow ability of the formation and increase the production and the injection.
