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.

음원 및 수신기의 3축 자동위치제어가 가능하고 정밀도가 향상된 탄성파 단면 영상화 및 자료처리 적용을 위한 해양 탄성파 축소모형 시스템을 개발하였다. 개발한 축소모형 시스템의 성능 검증 및 적용성을 파악하기 위하여 음원 및 수신기의 심도 변화에 따른 탄성파 자료를 취득하였다. 취득한 자료를 수치모형 실험 자료와 비교해본 결과 반사파의 경향이 일치하였다. 탄성파 축소모형 시스템의 적용성을 파악하기 위하여 암염 돔 모델에서 다중채널 탄성파 탐사를 수행하였으며, 속도 분석, Kirchhoff 구조보정 등의 자료처리 기법 적용하였다. 취득한 탄성파 단면과 지층 모델 단면이 일치하였으며, 실제 파동 전파 현상으로 나타나는 반사, 다중반사, 회절 등과 같은 현상이 발생한 것을 확인하였다. 본 연구에서 개발한 해양환경 탄성파 축소모형 시스템을 활용하여 현장 탐사와 유사한 자료를 경제적으로 취득이 가능하며, 탄성파 탐사 기법 모사, 현장 탐사 설계, 자료처리 알고리즘 검증 등에 활용될 것으로 판단된다.
