Abstract

Способ интерпретации данных электромагнитной разведки, проводимой методом переходных процессов, включает измерение переходной характеристики среды (характеристики становления вторичного электромагнитного поля среды) относительно группы коммутационных событий. Далее осуществляют моделирование измеренной переходной характеристики в результате первого коммутационного события из числа коммутационных событий, обусловленных переключением тока, после чего производят вычисление переходной характеристики по указанной модели для по меньшей мере одного обусловленного переключением тока коммутационного события, состоявшегося по времени прежде указанного по меньшей мере первого обусловленного переключением тока коммутационного события. Затем производят суммирование рассчитанной по модели переходной характеристики с измеренной переходной характеристикой от первого коммутационного события, а указанную сумму сравнивают с результатами измерений при электромагнитной разведке. Далее осуществляют коррекцию модели, а вычисление указанных суммарных переходных характеристик производят до тех пор, пока разность между указанными суммарными расчетными переходными характеристиками и указанными результатами измерений при электромагнитной разведке не станет меньше заданной пороговой величины.
