The invention discloses a high-reliability hydraulic ejector, which is characterized in that the body of the hydraulic ejector is provided with a pressing cap hole, a nozzle is positioned in a pressing cap, and the pressing cap is fixedly arranged on the pressing cap hole. The inner wall of the body is provided with an annular groove, the annular groove is communicated with the lower end opening of the body, and a lining is inserted into the annular groove from the lower end opening of the body. The lower end surfaces of the body and the lining are both provided with corresponding positioning grooves, positioning blocks are inserted into the positioning grooves so as to position the lining on the body in the circumferential direction, thus a jet hole in the lining is aligned with the nozzle, and the diameter of the jet hole is larger than the inside diameter of the nozzle and is smaller than the outer diameter of the nozzle. The lower end opening of the body is connected with a lower connector, and the positioning blocks are restricted in the positioning grooves by virtue of the inner end surface of the lower connector. The outer end surface of the pressing cap is fixedly provided with a gland. By arranging the lining made of a special wear-resistant material and the gland, inner scouring and backwashing problems of the hydraulic ejector in the oil and gas field on-site construction process can be effectively solved, the use reliability of the hydraulic ejection tool is greatly improved, and the number of construction sections is greatly increased.
