- Способ вибросейсмической разведки относится к геофизической разведке и может быть использован для поиска и разведки нефтяных, газовых и рудных месторождений при полевых исследованиях вибросейсмическим способом. Цель изобретения - повышение разрешающей способности и детальности разведки. Способ вибросейсмической разведки основан на возбуждении в среде вибраторами частотно-модулированных воздействий с нижней и верхней частотой возбуждения, группировании вибраторов и сейсмоприемников, накоплении воздействия, регистрации и получении коррелограмм и временных разрезов. Новизна способа заключается в том, что в нем оценивают кажущуюся скорость целевых отражений, определяют для кажущейся скорости комплексную амплитудно-частотную характеристику направленности группы вибраторов и сейсмоприемников, верхнюю частоту в воздействиях устанавливают равной правой граничной частоте, соответствующей эффективному значению комплексной характеристики, устанавливают количество накоплений, обеспечивающее отношение сигнал/помеха для целевых отражений, не менее 2, спектры зарегистрированных коррелограмм и временных разрезов экстраполируют по методу максимальной энтропии от правой граничной частоты в область высоких частот на величину частотного интервала не меньшего, чем полуразность верхней и нижней частоты воздействия и не большего, чем разность этих частот.
