In practical measurement of magnetotelluric sounding, the static displacement of apparent resistivity is a common phenomenon. Whether it can be identified and corrected efficiently will affect the accuracy of inversion and interpretation directly, especially on condition of regional static displacements. In a magnetotelluric profile with continuous static displacements, the apparent resistivity curves with the same polarization model of adjacent measurement points are less referable to each other, and how to make reasonable static displacement correction is the key to obtaining reliable inversion results. Based on lithologic analysis and experimental tests, a new static displacement correction method for large-point-distance condition is preliminarily summarized in this paper, which is named "the statistical averaging method of frequency points in first branch". In this method, statistical analysis is firstly conducted on the distortion measurement points in the study region, then the first three frequency points of each measurement point (same polarization mode) are averaged, and finally the gained averages of all the distortion measurement points are further averaged to obtain a target value, which is preset to the second frequency point of the first branch of the corresponding apparent resistivity curves with distortion. This method doesn't change the shape, but only changes the position of the first branch of the measuring point curve, so as to reach the preset position. Taking the measured data of magnetotelluric sounding in Zalut area as an experiment, the authors carried out the static correction test, and obtained a good application effect, which also indicates that the method is reasonable and applicable in the magnetotelluric sections with continuous static displacement under the condition of insufficient logging and physical property constraints.
