Combined interpretation of single-channel seismic and sub-bottom profiles in the western area of Hainan Island[J]. Marine Geology Frontiers, 2024, 40(2): 77-82. doi: 10.16028/j.1009-2722.2023.034 |
Based on the data of single-channel seismic and sub-bottom profiles collected in recent years, the issues of one-sidedness and inadequacy in the interpretation by single method were explored.. Joint interpretation was carried out using single channel seismic and shallow layer profiler synchronous measurement data in the western sea area of Hainan Island, South China. Results show that the joint interpretation has higher reliability in dividing shallow stratigraphic structures, from which disaster geological bodies could be identified, and the distribution of sea sand resources be delineated. Under the high demand for high-precision seismic data interpretation, the joint interpretation can greatly improve our understanding of geological conditions, reduce effectively the ambiguity of geological interpretation, and optimize the resource target areas such as marine sand. This study provided a tool for accurate and reliable data interpretation for ocean resource exploration and engineering construction.
