Abstract

Способ может включать в себя получение доступа к сейсмическим данным, создание волновой функции, которая задает, по меньшей мере отчасти, длину интервала корреляции, формирование локальных автокорреляционных функций для сейсмических данных с использованием длины интервала корреляции, выполнение взаимных корреляций между волновой функцией и каждой из локальных корреляционных функций для получения локальных значений коэффициентов взаимной корреляции, определение вторых производных локальных значений коэффициентов взаимной корреляции для получения локальных значений вторых производных и отображение локальных значений вторых производных на дисплее. Кроме того, раскрыты другие устройства, системы, способы и т.д.
