Abstract

Предложен способ оценивания качества данных о положении нижних горизонтов и данных о положении стволов скважин, содержащий построение модели положения нижних горизонтов из области геологической среды, включающей в себя данные о положении нижних горизонтов, при этом каждая точка в модели положения нижних горизонтов имеет выраженную количественно неопределенность положения, представленную через распределение вероятностей; построение модели положения стволов скважин, включающей в себя данные о положении стволов скважин, полученные на основании скважинных отбивок из скважин в области, при этом каждая скважинная отбивка соответствует геологическому объекту, определенному с помощью измерения, полученного в скважине, при этом каждая точка в модели положения стволов скважин имеет выраженную количественно неопределенность положения, представленную через распределение вероятностей; идентификацию общих точек, каждая из которых представляет собой точку в модели положения нижних горизонтов, которая соответствует скважинной отбивке из данных о положении стволов скважин; получение для каждой общей точки локального тестового значения, представляющего неопределенность положения; выбор некоторых, но не всех, общих точек и получение тестового значения на основании локальных тестовых значений выбранных общих точек; задание тестового предела погрешности положения для выбранных общих точек; и сравнение тестового значения с тестовым пределом для получения оценки качества данных.
