К вопросу автоматизированного контроля качества данных геофизических исследований скважин

Abstract

Работа посвящена развитию научных основ, методов и технологий первичного автоматизированного контроля регистрируемых данных при проведении геофизических исследований в скважинах. Решение вопроса о прекращении каротажа на определённой скважине зачастую связано с субъективными оценками экспертов. Авторы аргументируют необходимость использования автоматизированных средств обнаружения ошибок и контроля качества регистрируемых данных в процессе или непосредственно по завершению исследований. Приводится краткий анализ симптомов ненадёжности фрагментов записи. Предлагается алгоритм, использующий методы итерационного моделирования неполных данных с помощью многообразий малой размерности, для решения задачи оценки качества записи данных геофизических исследований скважин. Приводятся примеры, демонстрирующие высокую эффективность методов итерационного моделирования неполных данных с помощью многообразий малой размерности в задаче заполнения пробелов данных геофизических исследований, а также результаты численного эксперимента по решению задачи контроля качества данных электрического каротажа.

The development of scientific principles, methods, and techniques of the automated control of the primary data recorded in the geophysical well logging is considered. The issue of termination of logging on a particular well is often associated with subjective expert assessments. The need for automated detection of errors and quality control of the recorded data during or immediately upon completion of studies is discussed. A brief analysis of the unreliability symptoms of record fragments is provided. An algorithm using iterative modeling techniques of incomplete data with low-dimensional manifolds for solving the problem of assessing the quality of the well logging data is proposed. Examples demonstrating the high efficiency of the iterative modeling methods for incomplete data using low-dimensional manifolds in the problem of space filling of geophysical study data are given; and the results of the numerical experiments on solving the problem of data quality control of electric logging are provided.
