Abstract

Abstract:

The theory and basic features of velocity-depth linear model are introduced in this paper. With the velocity spectra data along a multi-channel seismic profile in the deep-water area of the South China Sea and by applying the velocity-depth linear model to the interpreted data of the profile, we obtained direct results for geological interpretation. In addition, through the creation of visual workflow and the consideration of horizontal variation of sedimentary interval velocity within the depth conversion procedures, we made the results of depth conversion more reliable. At the end, we discussed the limitation and further application of velocity-depth linear model in terms of both theory and practice, which would be considered in further work.

Key words: sedimentary stratum, velocity-depth linear model, time to depth conversion, velocity spectra, mean root square velocity, interval velocity, South China Sea basin deep-water area
