Abstract

Compaction is the only consideration for 'velocity-depth' linear model of sedimentary strata.With the velocity spectra data along a multi-channel seismic profile in deep-water area of South China Sea basin and by applying the 'velocity-depth' linear model to the interpreted data of the profile,the authors 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,the authors made the results of depth conversion more reliable.In the end,the authors gave a discussion on the limitation and further application of 'velocity-depth' linear model both from theory and practice,which deserves consideration in further work.

Key words： seismic profile complicated sedimentary area exponential formula power function 2 ^nd-order polynomial multi-functions fitting time-to-depth conversion
