一种震电波场联合提取瑞雷波频散特征的面波勘探方法

本发明公开了一种震电波场联合提取瑞雷波频散特征的面波勘探方法，包括步骤：获取联合采集的数据；其中，所述联合采集的数据包括：地震波数据和电场数据；将所述联合采集的数据进行联合成像处理得到叠加的频散谱；对所述叠加的频散谱进行提取处理得到频散曲线，并对所述频散曲线进行反演处理得到地层结构剖面。由于采用地震波数据和电场数据进行联合成像处理得到叠加的频散谱，并提取得到多模式频散曲线，在进行反演时大大降低反演的多解性，从而大大提高面波勘探的精度和稳定性。

The invention discloses a surface wave exploration method for jointly extracting Rayleigh wave frequency dispersion characteristics in a seismic wave field. The surface wave exploration method comprises the following steps of: acquiring jointly acquired data, wherein the jointly acquired data comprises seismic wave data and electric field data; carrying out joint imaging processing on the jointlyacquired data to obtain a superimposed frequency dispersion spectrum; and carrying out extraction processing on the superimposed frequency dispersion spectrum to obtain a frequency dispersion curve, and outperforming inversion processing on the frequency dispersion curve to obtain a stratum structure profile. As the seismic wave data and the electric field data are adopted to carry out combined imaging processing to obtain the superimposed frequency dispersion spectrum, and the multi-mode frequency dispersion curve is extracted, the multiplicity of solutions of inversion is greatly reduced during inversion, and the precision and stability of surface wave exploration are greatly improved.
