The utility model discloses a vibration cementing device, which relates to the field of cementing. The vibration cementing device mainly comprises an electric cable 2, a transformer 11 and an oscillator 5, wherein the two ends of the electric cable 2 are respectively connected with the output end of the transformer 11 and the oscillator 5; the oscillator 5 is provided with a pressure-resistant cavity 17 which is of a closed structure; a motor 13 and eccentric blocks 16 are arranged in the pressure-resistant cavity 17; one or more than two eccentric blocks 16 are arranged in the axial direction. According to the vibration cementing device, the annulus cement grout in the range of a full sleeve section is vibrated in the ways of transferring vibration waves and knocking a sleeve in a process of waiting on cement without influencing the conventional cementing process, the rheological properties of the grout are improved, and the cementing quality is improved.
