Abstract

В заявке описаны фазочувствительные измерения, которые осуществляет на множестве частот устройство для формирования изображения по данным метода сопротивлений в стволе скважины с непроводящим буровым раствором, которая пробурена в толще пород. Удельное сопротивление толщи пород может быть определено на основании фазочувствительных измерений с более высокой чувствительностью, чем это возможно при одночастотных измерениях. На основании известного удельного сопротивления и(или) диэлектрической постоянной бурового раствора также может быть определено отклонение прибора. Также может быть определено удельное сопротивление толщи пород, когда невозможно игнорировать его емкостное сопротивления толщи пород.
