Application of Seismic Motion Inversion in the Third Member of the Shahejie Formation in the Northeastern Kenli

Abstract

The reservoirs in the third member of the Shahejie Formation in the northeastern Kenli are thin and laterally changing, so the traditional seismic attributes and inversion techniques have no ideal prediction effects for them, which fails to meet the needs of exploration evaluation. With the first application of the Seismic Motion Inversion technique in the work area, based on the seismic data, and guided by sedimentary laws and seismic geological features, this study carried out the HF inversion by making full use of the constrained seismic logging parameters, through the process that the waveform similarity and spatial distance constrained the preferable seismic trace to participate in the inversion operation. The inversion results show that the sandstone body structure and distribution pattern in the study area are clear. This improves the prediction ability of interwell thin reservoirs, and well describes the overlap boundary of thin-layer sandstone, having guiding significance for the next exploration and deployment work in this area.
