Research and development of cross-well seismic processing system

Abstract

At present, there is not a complete set of data processing systems for cross-well seismic data in China, so the research and development of cross-well seismic processing systems is of great significance. This report introduces the 2D/3D forward modeling of cross-well seismic complex media, 2D/3D imaging of cross-well seismic complex media, CT imaging of cross-well seismic complex media, and time-varying three-component wave field polarization synthesis and decomposition, identification and separation of wave fields under strong environmental noise, pre-stack attribute parameter extraction and inversion of cross-well seismic data, cross-well seismic inverse filtering, cross-well seismic amplitude processing technology, and cross-well seismic time-frequency analysis and attribute extraction methods and technology, and introduces the geophysical effects of the system through the processing of model and actual cross-well seismic data. The result maps listed in the article show that the developed cross-well seismic processing system is accurate, reliable, and advanced, filling the gap in the cross-well seismic data processing system in my country.
