This paper introduces the structure of cementing tool - flip-plate hydraulic oscillating casing shoes and the principle of vibration, and gives the field test method of hydraulic pulse vibration cementing technology.On the field application results of Daqing Oilfield and Nanyang Oilfield The results show that the vibrating effect of using flip-plate hydraulic vibrating casing shoe is obvious. When the vibration field frequency is 60-70Hz, the vibration energy of vibrating cementing casing is 7.5 times that of conventional cementing. In cementing well of Daqing Oilfield, All of them were of high quality, and the cementing factor was increased by 0.01 ~ 0.030 bags / m than that of the conventional cementing in this block. This technique improved the cementing displacement efficiency, and thus improved the cementing quality and for the future vibration Cement technology provides the basis for the study
