Based on deep understanding of the methodology and processing flow, this paper discussed key technologies such as migration parameters and migration velocity analysis, and obtained the proper migration velocity field and high imaging precision seismic sections by applying prestack time migration processing technique to gas hydrates seismic data processing in the South China Sea.Compared to poststack time migration, the results of practical data processing using prestack time migration show that imaging precision of sections are improved greatly, and reflection characteristics of various geological information are more abundant, which can improve the accuracy of gas hydrates interpretation effectively.hemas-microsoft-com:office:office" />
