The utility model provides a double-eccentric correction device of a well opening packaging box, which is applied to a well opening of an oil pumping well and is matched with a well opening device and the packing box. The lower end of an inner thread short section is horizontally welded with a first eccentric annular steel plate and the lower end face of the first eccentric annular steel plate is welded with a tapered outer thread short section; the lower end of the tapered outer thread short section is in threaded connection with a tapered inner thread short section; the lower end of the tapered inner thread short section is horizontally welded with a second eccentric annular steel plate; and an outer thread short section is welded on the lower end face of the second eccentric annular steel plate. The double-eccentric correction device has the effects that in a normal production process of an oil well, a polish rod is aligned with the center of the well opening packaging box, so as to solve the problems that the polish rod and the packaging box are damaged due to that the polish rod and the packaging box are eccentrically abraded, prolong the service life of a packing, reducing times of replacing the packing, guarantee the oil well production rate, improve the oil well yield and reduce the labor intensity of workers.
