Abstract

Раскрыты методы, относящиеся к геофизической съемке. В некоторых вариантах осуществления судно для морской съемки буксирует несколько сейсмоприемных кос в дополнение к вибрационным источникам, развернутым относительно сейсмоприемных кос. В некоторых вариантах осуществления судно буксирует вибрационные источники, излучающие волны в различных частотных диапазонах в различных зонах развертывания. В некоторых вариантах осуществления один или более источников приводят в действие при помощи различных функций частотной развертки свип-сигнала, различных схем активации и/или различных длительностей свип-сигнала. Различные раскрытые методы для получения результата обработки геофизических данных могут потенциально упростить оборудование, применяемое для буксирования источников, уменьшить сложность съемки без уменьшения разрешения, увеличить разрешение без увеличения сложности съемки, улучшить энергетическое содержание волн, восстанавливаемое на основе глубоких отражений, и/или уменьшить воздействие на окружающую среду излучения сейсмических волн.
