Abstract：The ordinary structure mapping methods mainly include two kinds in an area of linear or quasi-linear variation of velocity with depth:the one is space correction for isochronic t0 map resulted from interpretation of stack section;the other is to using uniform velocity for time-depth conversion of isochronic t0 map resulted from interpretation of migration section.Aimed at character of that Mesozoic-Paleozoic stratum velocity is non-linear variation with depth vertically and severe change laterally,the paper studied a mapping series of layer stripping in different area respectively,that is general layer stripping,equivalent variable velocity layer by layer and equivalent mapping step by step.These methods successfully eliminate the inadaptability of ordinary mapping methods in an area where the carbonate reservoir is major target,have advantages of simple and easy-use and achieve a good result in a process of real application.
