Abstract

Описывается компьютеризированный метод и система компьютерной томографии с использованием пучков для создания оптимизированных сейсмических изображений и моделей геологической среды, не зависящих от структуры отражающей границы. Зарегистрированные сейсмические данные преобразовываются в пучки данных, которые сравниваются со смоделированными (путем решения прямой задачи) пучками, используя модель геологической среды, включающую в себя модель скорости для вычисления траекторий лучей и сейсмического изображения для определения отражающих границ. Томографические обновления модели геологической среды и модели скорости основаны на несовпадениях между пучками данных и аналогичными пучками, смоделированными (путем решения прямой задачи) по модели скорости и сейсмическому изображению. Обновленная модель геологической среды и сейсмическое изображение лучше описывает истинное распространение пучков в геологической среде.
