Abstract

Система звукового каротажа содержит зонд в стволе скважины, который излучает звуковые волны посредством одного или нескольких дипольных источников для оптимального возбуждения в стволе скважины дипольных звуковых волн с изгибными модами. Сначала в системе определяется частота Эйри ствола скважины. Затем дипольные источники возбуждаются на частоте дипольного возбуждения, выбранной на основе частоты Эйри.Отчет о международном поиске был опубликован 2002.05.16.
