COMPLETE WAVE FIELD INVERSION WITH QUALITY FACTOR COMPENSATION

摘要

FIELD: geophysics.;SUBSTANCE: invention relates to geophysics and may be used in seismic data processing. Disclosed is a method, which includes the stages, at which the high-speed model formed when performing the process of acoustic full wave field inversion is obtained. Computer model is generated by variable Q by applying pseudo-immigration Q to processed seismic data of geological environment, wherein the speed model is used as a controlled constraint in the pseudo-immigration Q. A finite velocity model of the geological environment is formed by means of a computer, in which amplitude attenuation caused by gas anomalies in the geological environment is compensated for when performing the viscous-acoustic complete inversion of the wave field, wherein the model of the variable Q is fixed during the process of viscous-acoustic complete inversion of the wave field.;EFFECT: higher accuracy of obtained data is provided.;13 cl, 6 dwg
