METHOD FOR THE SYSMIC DATA INVERSION OF THE VERTICAL SYSMIC PROFILE (VSP) DATA IN A PETROLEUM FIELD WITH A UNDERGROUND FORMATION PENETRATED BY A WELL, AND SYSMIC DATA PROFILE (SYSICAL) DATA SYSTEM INVERTED OF THE PHYSICAL PROFILE.

摘要

method for the inversion of seismic data from vertical seismic profile data (vsp) in an oil field with an underground formation penetrated by a well, seismic data inversion system of vertical seismic profile data (vsp), and a half computer readable. method for inversion of seismic data from vertical seismic profile data (vsp) in an oil field. the method includes obtaining a model of the initial velocity of the underground formation that includes the propagation velocities of the acoustic wave in the vicinity of the well; determining an acquisition geometry for obtaining vsp data, the acquisition geometry comprising a plurality of receiver locations within the well and a source position; conduct a seismic data survey to obtain vsp data based on acquisition geometry; analyze the direct signals of arrival of the data obtained by vsp to generate data of transit time for the propagation of the waves from the place of origin to the plurality of places of the receiver; modify the initial speed model to generate an updated speed model by performing a tomographic inversion of the transit time data; generate an elastic model of the underground formation through the formation of the seismic data inversion of the vsp data using the model.
