Abstract

Предложен способ определения пространственного распределения удельного сопротивления в горных породах, окружающих скважину, содержащую проводящую трубу. Способ включает измерение удельного сопротивления горных пород с использованием измерений утечки тока по трубе в выбранных аксиальных положениях. Электромагнитные свойства горных пород измеряют изнутри трубы. Измерения электромагнитных свойств соответствуют большему аксиальному расстоянию и большему горизонтальному расстоянию по сравнению с измерениями удельного сопротивления по утечке тока. Измерения утечки тока и электромагнитные измерения совместно преобразуют для получения модели пространственного распределения.
