The invention discloses a hydraulic thrust type rubber seal flushing pipe assembly of a well drilling top driving device. The hydraulic thrust type rubber seal flushing pipe assembly of the well drilling top driving device comprises an upper subassembly and a lower subassembly, and the external diameter of the upper subassembly and the external diameter of the lower subassembly are both matched with the size of the installing position of the top driving device. The hydraulic thrust type rubber seal flushing pipe assembly of the well drilling top driving device has the following advantages that the structure is simple, machining is convenient, and investment cost is low; application prospects are good, and the assembly can be used in cooperation with the existing well drilling top driving device; hydraulic thrust force and rubber seal parts are used in a matched mode, the seal self-repairing goal is realized, strict leakproofness of a tool is guaranteed, repairing shutdown time is shortened, operation timeliness is improved, and an escort is provided for downhole operation safety.
