The invention discloses a well fixing device capable of being multi-directionally vibrated. The well fixing device capable of being multi-directionally vibrated comprises a cylindrical body (1); the upper section of the body (12) is provided with at least one worm wheel section (2); the worm wheel section (2) is formed by a flow guide disc (21), a mandrel (22), a worm wheel blade (23) and an eccentric block (24); the lower section of the body (1) is internally provided with a plum-blossom-shaped rotor (3) and a plum-blossom-shaped stator (4); and a compression spring (5) is arranged between the lower end of the plum-blossom-shaped rotor (3) and the body (1). The well fixing device is beneficial for improving the well fixing quality and mainly has the effects from the following aspects that (1) underground cement slurry can be cut so as to reduce the static cutting force of the cement slurry; (2) the multidirectional vibration of the device and the cutting movement of an eccentric worm wheel sheet are beneficial for eliminating air bubbles in the cement slurry; (3) the multidirectional vibration generated by a tool can be used for improving the replacing efficiency; and (4) prepad fluid and washing solution are particularly suitable for effectively washing a well hole.
