[Abstract]:With the rapid progress of seismic survey and exploration technology, geological researchers are faced with new challenges in dealing with seismic data, and put forward new requirements for the accuracy and rationality of seismic exploration data. Seismic data generally carry a large amount of uncertain information, so it is very important to study the uncertainty of seismic data to solve the problem of reservoir storage. Taking seismic attribute data as an example, the uncertainty of seismic attribute is studied in this paper, and the accuracy and rationality of uncertainty model of seismic attribute are analyzed and discussed with visual analysis method. In the research process of uncertain modeling method, it is very important to combine the experience and opinions of professional geological personnel to manage and operate interactively. Therefore, this paper also designs an interactive visual analysis system, according to the suggestions and requirements of geological experts to modify the established uncertainty field model, so as to obtain a more reasonable uncertainty field model. In this paper, the main work and innovation of visual analysis based on seismic multi-attribute uncertainty include: (1) the uncertainty of karst boundary range corresponding to seismic attribute data is studied. In this paper, a method for modeling uncertainty of boundary data of multi-attribute caverns is proposed, and the surface with uncertainty is generated by using divergence point display. According to the uncertainty modeling method of each seismic attribute data, the uncertainty field of the corresponding boundary data points of the karst cave body is established, and the uncertainty field of the karst body boundary divergence point corresponding to each attribute is established. The method of evidence theory is used to fuse it. Finally, an uncertain region of cavern boundary is obtained, which is based on the established uncertainty field model of dispersion point of karst cave boundary in seismic attribute data. In this paper, a new visual analysis framework based on seismic attribute uncertainty and human-computer interaction process is proposed. On the basis of the visual analysis framework and human-computer interaction, a visual analysis system based on uncertainty is designed and implemented in this paper. The system is used to interactively analyze the uncertainty field model of seismic attribute object. The accuracy and rationality of multi-attribute uncertainty field are analyzed and discussed by using this system combined with the visual analysis method based on human-computer interaction. Finally, an ideal uncertainty region of the object boundary is obtained.
