Abstract

Изобретение относится к способу и устройству для определения удельного сопротивления геологической формации вокруг ствола скважины, снабженной металлической обсадной колонной. К обсадной колонне прикладывают электрический ток, чтобы подать ток в указанную формацию на заданном уровне, ток шунтируют посредством цепи обратной связи, находящейся в контакте с обсадной колонной на каждой стороне от заданного уровня. Цепь выполняют так, чтобы гарантировать, что ток, протекающий по обсадной колонне на заданном уровне, будет меньше по сравнению с током, протекающим по шунту. Определяют разность между падениями напряжений на соседних участках обсадной колонны, находящихся на каждой стороне от измерительного уровня, и получают ток (Ifor) утечки.Международная заявка была опубликована вместе с отчетом о международном поиске.
