In order to improve the instability problem of downword continuation in its conventional calculation�� we propose a method of calculating normalized full gradient of gravity anomalies based on Taylor series iteration method for rapid and stable downward continuation�� The experiment of infinite horizontal cylinder proves that the GH field characteristics of this method perform a single high value and the maximum position coincides with the location of model centroid�� The asymmetric-density oil storage sphere-coronal model prove that this method has still distinguished the characteristics of“one less value between two high values”�� The method of Fourier series and Fourier transform do not when the thickness of the oil storage part is low�� These fully illustrate that normalized full gradient of gravity anomaly computation method based on Taylor series iterative not only enhances the stability of calculation result��also improves the anomaly resolution��
