Abstract

Раскрыты методики, связанные с конфигурированием морской сейсмической разведки. В некоторых вариантах осуществления судно (210) может быть соединено с одним или более сейсмических источников (220) и одной или более сейсмоприемных кос (250), а второе судно (230) может быть соединено с одним или более сейсмическими источниками (240) с дальним выносом. Источники (220) с ближним выносом могут быть выполнены с возможностью активации в соответствии с интервалом между пунктами взрыва; источники (240) с дальним выносом могут быть выполнены с возможностью активации в соответствии с более длинным интервалом между пунктами взрыва. В некоторых вариантах осуществления более длинный интервал между пунктами взрыва может быть кратным интервалу между пунктами взрыва источника с ближним выносом. Определение первого и второго интервалов между пунктами взрыва может быть частично предусмотрено на основе, например, частот волн источников с дальним выносом, требований процесса полноволновой инверсии или различных параметров конфигурации сейсмической разведки.
