Abstract

Данные сейсмической разведки преобразуются в том данных подповерхностных структур, который пользователь может видеть, чтобы понять и анализировать подповерхностные структуры в районе сейсмической разведки. По меньшей мере, некоторые из раскрытых систем и способов применяют трехмерную миграцию по времени возврата с использованием волновых уравнений, адаптированных для использования в пластах, имеющих наклонную поперечную изотропию. Относительно существующих способов раскрытые системы и способы опираются на незначительное число аппроксимаций и испытывают незначительное число ограничений на обстоятельства, в которых они могут применяться. Более того, из-за того, что раскрытые волновые уравнения выводятся из закона Гука (и, следовательно, они действуют в областях, которые непосредственно связаны с физическими величинами), они демонстрируют повышенную стабильность по сравнению с существующими способами. Специалисты по анализу данных сейсмической разведки, применяющие раскрытые системы и способы, могли бы получать улучшенные изображения подповерхностных структур и могли бы быть способны лучше идентифицировать месторождения и залежи для коммерческого использования.
