Abstract

Способ буксирования группы сейсмоприемников для сбора морских сейсмических данных в водоеме включает буксирование набора сейсмических кос, пространственно разнесенных в поперечном направлении, позади сейсморазведочного судна в воде. Поперечное расстояние между соседними сейсмическими косами представлено величиной L. По меньшей мере два сейсмоисточника, пространственно разнесенных в поперечном направлении, буксируют позади сейсморазведочного судна. Поперечное расстояние между по меньшей мере двумя сейсмоисточниками представлено величиной kL, где k является константой и не превышает количества сейсмических кос.
