Abstract

В способе сейсмической съемки, описанном в настоящем документе, используют группу приемников и методологию обработки, которые предназначены для ослабления естественных фоновых сейсмических помех, которые регистрируют во время съемки вместе с сейсмическими данными. При таком подходе используют знания о том, что естественные фоновые сейсмические помехи имеют меньшую фазовую скорость, чем сейсмические сигналы, которые используют для построения изображений и инверсий и в некоторых вариантах осуществления эти помехи могут приходить с конкретных предпочтительных направлений. Раскрываемый способ включает в себя две стадии: 1) определение по предварительным сейсмическим данным диапазона фазовых скоростей и амплитуд естественных фоновых сейсмических помех, в котором преимущественно содержатся помехи, а также степени, до которой необходимо ослабить эти помехи; 2) проектирование съемки и способа обработки для ослабления этих помех относительно требуемого сигнала.
