Development of 3-axis Precise Positioning Seismic Physical Modeling System for Seismic Imaging and Data Processing

Abstract

A seismic physical modeling system capable of automatic 3-axis positioning control of seismic sources and receivers was developed to allow more accurate seismic imaging and data processing. To verify the applicability of the system, data were acquired for sources and receivers at various depths. Comparison to numerical data showed that the acquired data showed similar reflected wave trends. A multi-channel seismic survey was performed at a salt dome model to determine the applicability of the seismic physical modeling system, and data processing such as velocity analysis and Kirchhoff migration was carried out. The seismic cross-section image acquired was consistent with that of the geological model, and the primary reflection, multiple reflection, and diffraction data obtained agreed with real wave propagation data. The seismic physical modeling system developed allows the acquisition of modeling data that is similar to field data in an economical and efficient manner. This data can be used for various purposes, such as to simulate seismic data acquisition, design seismic explorations, and investigate data processing algorithms.
