Уважаемые коллеги!
26 февраля (среда) 2025 г. в 10:00 в конференц-зале ИНГГ СО РАН (к. 315) состоится геофизический семинар:
Устройства с тороидальными катушками для решения актуальных задач нефтепромысловой геофизики: численное моделирование
Докладчик: к.т.н. Михайлов Игорь Владиславович, старший научный сотрудник лаборатории многомасштабной геофизики
Аннотация: В докладе представлены результаты численных экспериментов (двумерное и трёхмерное конечно-разностное моделирование), направленных на расширение применимости геофизических устройств с тороидальными катушками в практике нефтепромысловой геофизики. Установлена эквивалентность сигналов каротажного зонда с тороидальными катушками в тонкослоистой и электрически макроанизотропной моделях среды. Выполнена численная оценка влияния проводимости корпуса на разрешающую способность каротажного зонда. Выявлены особенности сигналов зонда в разрезах наклонно-горизонтальных скважин относительно вертикальных, включая сравнение с широко используемыми электрокаротажными зондирующими системами. На базе электролитического бака со скважиной ИНГГ СО РАН согласованы синтетические и экспериментальные сигналы каротажного зонда с тороидальными катушками, с построением трансформаций измеряемых сигналов в кажущиеся удельные электросопротивления. Предложена компактная система для определения удельного электросопротивления цилиндрического керна как во время бурения, так и при лабораторных измерениях.
