Реферат:	rus: Численно исследуется одномерная нестационарная задача электромагнитоупругости пористых насыщенных сред при импульсном воздействии электромагнитным квазистационарным полем. Проиллюстрирована применимость спектрального метода Лагерра к одномерной динамической задачи импульсного воздействия, описываемого уравнениями электомагнитоакустики. Численно установлены особенности акустического отклика на импульсное электромагнтное воздействие: найдена связь амплитуд «поперечных» акустических волн, пришедших на внутреннюю сторону обсадной колонны от параметров, характеризующих среду и внешнее электромагнитное воздействие. Полученные результаты создают основу для разработки технологических методов измерения электроакустического параметра и электропроводости среды, расположенной за обсадной колонной. eng: This paper numerically studies the one-dimensional non-stationary problem of the electromagnetoe-lasticity of porous saturated media for a pulsed electromagnetic quasi-stationary field. The applicability of the Laguerre spectral method to the one-dimensional dynamic impulse action problem de-scribed by the electromagnetoacoustics equations is illustrated. The acoustic response to the pulsed electromagnetic effect is numerically determined: there is found a correlation between the ampli-tudes of "transverse" acoustic waves that have come to the inner side of the casing from the parame-ters characterizing the medium and the external electromagnetic effect. The obtained results form the basis for the development of technological methods for measuring the electroacoustic parameter and the electrical conductivity of the medium located behind the casing.
