Abstract

The embodiment of the invention provides a seismic imaging method and device based on differential tectonic deformation simulation. The method comprises the following steps: simulating a deformation and interaction process between at least two geological stratums by applying a differential tectonic deformation experimental model so as to complete a differential tectonic deformation process between the geological stratums; performing CT scanning and imaging processing on the differential tectonic deformation experimental model to generate a structure and speed model corresponding to each geological layer; and obtaining seismic imaging data corresponding to each geological layer based on seismic acquisition data obtained after seismic simulation processing is performed on the difference structural deformation experimental model and the structure and speed models corresponding to the corresponding geological layer. According to the method, the differential tectonic deformation simulation process of at least two geological stratums in a complex tectonic zone can be realized, and the efficiency and accuracy of the differential tectonic deformation simulation process can be effectively improved; meanwhile, the reliability of an earthquake imaging process and the accuracy of an earthquake imaging result can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of physical simulation, in particular to a seismic imaging method and device based on differential structural deformation simulation. Background technique [0002] Since the 19th century, physical simulation experiments of structural deformation using experimental sandboxes have been widely used in the study of plate tectonics and petroleum-bearing sedimentary basin structures. [0003] At present, the structural deformation pattern visible to the naked eye obtained in the experiment is often used as a comparative analysis with the underground deformation pattern shown by seismic reflection data. However, the seismic reflection structural pattern obtained by using the seismic wave propagation law in the underground is the result of manual acquisition and processing. The real and visible structural styles in the experiment belong to different types of research data, so they cannot directly and accur...
