Abstract

Раскрыты способы и системы разделения сейсмических данных, связанных с импульсным и неимпульсным источниками. Импульсный и неимпульсный источники могут буксироваться в водоеме отдельными исследовательскими судами. Приемники одной или более сейсмических кос, буксируемых в водоеме над подземной формацией, генерируют сейсмические данные, представляющие отраженное волновое поле, создаваемое подземной формацией в качестве отклика на отдельные волновые поля источников, генерируемые одновременной активацией импульсного и неимпульсного источников. Способы и системы включают в себя разделение сейсмических данных на сейсмические данные импульсного источника, связанные с импульсным источником, и сейсмические данные неимпульсного источника, связанные с неимпульсным источником.
