The invention provides a high-blade small-hub auger propelled tidal sea amphibious workboat, and relates to the technical field of ships, the tidal sea amphibious workboat comprises a boat body, an auger propeller and a power system, and the power system is connected with the auger propeller; the auger propeller comprises spiral blades and a roller hub, and the spiral blades are fixedly arranged on the periphery of the roller hub; the ratio of the height of a spiral blade of the auger propeller to the radius of a drum hub is not less than 1; the ratio of the sludge discharge amount of a roller hub of the auger propeller to the weight of the whole ship is not larger than 1. According to the tidal sea amphibious workboat, by reducing the diameter of the roller hub and increasing the height of the spiral blade, the resistance borne by the auger propeller is reduced, and the effective thrust of the auger propeller is increased; the rotary disturbers are additionally arranged at the bow and/or the stern of the shi
