Abstract

Раскрыты система и реализуемый с использованием компьютера способ определения характеристик интересующей зоны разреза на основе сейсмических данных. В варианте осуществления способ включает в себя получение сейсмических данных, представляющих зону разреза, и исходной модели свойств геологической среды для зоны разреза, выполнение прямого моделирования с использованием исходной модели свойств геологической среды, чтобы создать смоделированные сейсмические данные с такими параметрами наблюдений, как у фактических сейсмических данных, преобразование смоделированных и фактических сейсмических данных в частотную область временного преобразования Фурье, чтобы создать смоделированные в частотной области и фактические сейсмические данные, причем смоделированные в частотной области и фактические сейсмические данные включают в себя амплитудную часть и фазовую часть, измерение несовпадения между смоделированными сейсмическими данными частотной области и фактическими сейсмическими данными частотной области, чтобы создавать остаточные сейсмические данные частотной области, выполнение развертывания фазы фазовой части некоторых наблюдаемых частотных составляющих остаточных сейсмических данных частотной области, чтобы создать развернутую остаточную фазовую часть, и обращение развернутой остаточной фазовой части, чтобы определить требуемые характеристики интересующей зоны разреза, причем обращение минимизирует целевую функцию, заданную для измерения несовпадения. Способ может также включать в себя экстраполяцию фазы. Кроме того, способ может включать в себя второй этап обращения, использующий
