2. The hydraulically driven radial vibration cementing sub of claim 1, wherein: the filter device is in threaded connection with the opening at one end inside the body (1), the filter device is a filter basket (2), and a plurality of filter holes (7) are formed in the side wall of the filter basket (2) along the radial direction of the filter basket.
3. A hydraulically driven radial vibration cementing sub as claimed in claim 2, wherein: the filter basket (2) is of a cylindrical structure with two open ends, one end of the filter basket (2) close to the vibration unit is provided with a convex edge, and the outer wall of the convex edge is provided with external threads fixedly connected with the internal threads at the end part of the body (1); the convex edge is also provided with a plurality of filtering holes (7) along the length direction, and the filtering holes (7) on the convex edge are circumferentially arranged.
4. The hydraulically driven radial vibration cementing sub of claim 1, wherein: the positioning edges (10) and the positioning grooves (11) are fixed together by spot welding or metal glue.
5. The method of using a hydraulically driven radial vibration cementing nipple of claim 1, wherein: when the device is used, the device is placed at the lower end of the casing string, impurities in fluid are filtered through the filter basket, then the fluid is guided to impact on the blades of the polarized water wheel ball through the guide cylinder, the blades rotate along the bearing, and periodic load acting on the axial direction of the casing string is generated during rotation due to the fact that the blades with uneven weight are uniformly distributed on the polarized water wheel ball, so that periodic radial vibration is generated; under the action of the periodic load, the casing string vibrates up and down, vibration waves are transmitted upwards from the bottom of the well, a vibration wave field is formed in the whole annular space, under the action of the vibration waves, the casing string and drilling fluid vibrate, and the vibration waves wash out mud cakes on the casing string and the well wall, so that the viscosity of the drilling fluid is reduced, and the flow property of the drilling fluid is improved.
