Abstract
Способ электромагнитной дефектоскопии в многоколонных скважинах, заключающийся в измерении э.д.с, наведенной в приемной катушке вихревыми токами, возбуждаемыми в стальных обсадных или насосно-компрессорных трубах процессом спада электромагнитного поля, вызванного зондирующим импульсом тока намагничивания в генераторной катушке, отличающийся тем, что для возбуждения генераторной катушки используют чередование импульсов тока намагничивания различной длительности в диапазоне от 10 до 200 мс через каждые 200 мс и измерение параметров труб малого диаметра осуществляют после выключения возбуждающих импульсов тока намагничивания меньшей длительности, например в диапазоне от 10 до 40 мс, а измерение параметров труб большего диаметра производят после выключения возбуждающих импульсов тока намагничивания с большей длительностью, например в диапазоне от 40 до 200 мс.A method for electromagnetic flaw detection in multi-string wells, which consists in measuring the emf induced in the receiving coil by eddy currents excited in steel casing or tubing by the process of decay of the electromagnetic field caused by a probing pulse of the magnetization current in the generator coil, characterized in that to excite the generator coil, alternation of magnetizing current pulses of various durations in the range from 10 to 200 ms every 200 ms is used, and the measurement of the parameters of pipes of small diameter is carried out after turning off the excitation pulses of the magnetizing current of a shorter duration, for example, in the range from 10 to 40 ms, and the measurement of parameters pipes of larger diameter are produced after turning off the exciting pulses of the magnetization current with a longer duration, for example, in the range from 40 to 200 ms.
