Abstract

Предложен реализуемый на компьютере способ стохастической инверсии, предназначенный для оценивания параметров модели земли. В одном примере осуществления этот способ использует выборочный стохастический метод для определения функций плотности вероятности (ФПВ) параметров модели, которые определяют граничную многомерную модель разреза. В некоторых примерах осуществления используется выборочный метод под названием "Марковская цепь Монте-Карло" (МЦМК). Выборочный метод МЦМК относится к классу методов "выборки по значимости", в которых из распределения апостериорной вероятности выборка делается соразмерно способности модели согласовываться с геометрией системы наблюдений. В другом примере осуществления инверсия представляет собой совместную инверсию множества наборов геофизических данных. Примеры осуществления данного изобретения относятся также к компьютерной системе, имеющей такую конфигурацию, чтобы можно было реализовать способ оценивания параметров модели с целью точной интерпретации разреза земли.
