Using Wide-Angle Reflection Wave Technology to Detect Seismic Inversion Data of Complex Geological Structure Zone for a Future Smart World

Abstract

Abstract The South Yellow Sea has complex geological conditions such as small seismic wave impedance differences between shallow and deep marine sedimentary formations. The energy of the reflection wave in the deep phase is weak at the same phase axis, making it difficult to identify the effective reflection information of the marine target layer, especially the deep parts covered by high-speed layers. It is extremely difficult to image the carbonate stratum of the Mesozoic and Paleozoic. For this reason, wide-angle reflection wave technology is used to detect seismic inversion data of complex geological structures. According to the comparative analysis of the actual seismic data and inversion simulation data in the South Yellow Sea area, it is verified that under the condition of complex geological structure, with the aid of inversion simulation data, effective waves and interference waves can be identified, which can guide the optimization of acquisition parameters in the deep target formation area of the South Yellow Sea, where imaging is difficult, in view of the factors affecting the imaging accuracy of the marine carbonate formation of the middle and Paleozoic, and this is conducive to improving the acquisition parameter quality of seismic data.
