| description | The invention discloses a method and device for determining the maximum annular pressure as well as a storage medium, and belongs to the field of oil field development. The method comprises the stepsthat the formation temperature, the cement sheath permeability, the cement sheath depth, the cement sheath interface pressure, the annular sectional area and the wellhead air chamber volume of a gas well are obtained; according to the formation temperature, the cement sheath permeability, the cement sheath depth, the cement sheath interface pressure, the annular sectional area and the wellhead gaschamber volume of the gas well, multiple annular pressures in one-to-one correspondence to the multiple gas channeling times are determined; and according to the multiple annular pressures, the maximum annular pressure of the gas well is determined. By means of the method for determining the maximum annular pressure, an important basis can be provided for safety production of the gas well.
