MULTICOMPONENT SEISMIC INVERSION OF VSP DATA

摘要

A kind of method,Oil field for seismic inversion vertical seismic profiling (VSP) (VSP) data. This method includes that obtain the stratum of initial velocity model include the velocity of sound propagated of wave close to wellbore, determine acquisition geometry for obtaining VSP data, including receiver position in pit shaft and source position, carry out seismic survey, to obtain the acquisition based on the VSP data, the VSP data of arriving signal are analyzed to generate position of the data propagated by Time Wave from source to receiver, modify initial velocity model, the data of the rate pattern tomographic inversion transition time updated are generated by executing, it generates elastic force model and carries out stratum, the rate pattern updated is used by the VSP data of seismic inversion, the operation for adjusting oil field is based on elastic model.
