Magnetotelluric static displacement correction method based on the inversion model

Belonging to one inventive data TECHNICAL FIELD The magnetotelluric sounding method based on static shift correction of magnetotelluric inverse model. Correction method of the present invention comprises the following steps: In the initial design model inversion added superficial assigned a high resistance or low resistance of generalized static shift resistivity, i.e. the presence of static displacement resistance of the mesh model corresponding to the measuring point generalized static displacement rate assigned to participate resistivity inversion, so as to realize the correction of static displacement of the measuring point, the inversion result obtained with a static shift correction effect. Wherein the resistivity of said resistive bodies is greater than the background resistivity, the resistivity of the low resistivity of less than background resistivity. Correction method of the present invention is carried out on the basis of the theoretical three-dimensional magnetotelluric static displacement correction, so that correction result closer to the actual subsurface electrical structure, more precise information; and achieves static shift is corrected by the initial design model, reduce embodiment statics complexity, and work to achieve zero cost.
