METHOD FOR MODELLING KINEMATIC SEISMIC DATA PROCESSED WITH AT LEAST ONE MOTION OPERATOR

摘要

A method for modelling kinematic seismic data processed with at least one motion operator, wherein the mid-point (N1) of a transmitter (S)/receiver (R) system is determined, a ray tracing for the system is established relative to a given reflector, the ray parameters are processed using a motion operator to provide a first arrival point (N'1) located on the model, the position deviation ( DELTA E) between the reference points (N) and the point (N'1) is determined and compared with a predetermined deviation ( DELTA e), and an iteration is performed on each new arrival point (N'i) until the deviation ( DELTA E) is the same as or smaller than the predetermined deviation ( DELTA e). The method is particularly useful in tomography.
