METHODS AND SYSTEMS FOR CONNECTION PSEUDOSURFACE SELECTED POINT PLACES INTO SPEED OF SEISMIC WAVES MODELS

摘要

FIELD: data processing.;SUBSTANCE: invention relates to geophysics and can be used during seismic data processing. At least some of illustrated versions of implementation relate to methods, including updating model speed of seismic waves by correlating prediction make with measured logging diagram, creation of pseudosurface selected point place in modelled underground horizon based on correlation and modification of at least part of model of seismic wave velocity based on pseudosurface selected point place. Method also involves repeated calculation of simulated underground horizon based on model of speed of seismic waves due to formation of modified surface, and display of modified surface on computer system display.;EFFECT: high accuracy and reliability of obtained data.;27 cl, 7 dwg
