The invention discloses a high-pressure thin-wall large-diameter extrusion oil tank which comprises an oil tank cylinder, a supporting mandrel, a piston and an end cover. One end of the oil tank cylinder of a cylindrical structure is connected with the end cover. The supporting mandrel is arranged on the central axis of the oil tank cylinder. A displacement sensor is installed in an inner cavity of the supporting mandrel and used for measuring the oil storage amount in the oil tank. The supporting mandrel is sleeved with the piston in a sealed manner. The oil tank cylinder is divided into an oil cavity and a gas cavity through the piston. The piston is provided with two Y-shaped sealing rings for isolating oil from gas and matched with the inner wall of the oil tank cylinder. The end cover is a cover body protruding outwards and is welded to the oil tank cylinder in a stepped manner. Double guidance is set for the inner ring and the outer rings of the piston so that the oil storage amount of the oil tank can be increased. Due to the fact that the outer rings of the piston are the Y-shaped rings, the capacity of the piston adapting to deformation of the cylinder is high, the sealing manner is adopted for effectively compensating for seal failure caused by deformation of the cylinder, and the oil tank has the good sealing effect when working under the conditions of high vibration and high impact magnitude.
