Представлен краткий обзор программных продуктов, позволяющих моделировать волновое поле с учетом добротности среды. Проанализированы полученные результаты моделирования, а также возможность дальнейшего использования для других исследований. Сравнение алгоритмов расчета добротности среды на простой модели в зависимости от соотношения сигнал/помеха дает реальную оценку погрешности определения Q-фактора на модельных сейсмических данных, что можно использовать на практике.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the assessment of the Q-factor of the medium using model seismic data. Investigations include the brief overview of seismic modeling software that allows modeling the wave field accounts Q-factor. The comparison of results obtained with Q-calculating algorithms and model seismic data with different signal to noise ratio gives a real estimate of the error in determining of Q-factor. This fact can be taken into account in the time processing of the real seismic data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обработка сейсмических данных</kwd><kwd>добротность</kwd><kwd>коэффициент поглощения</kwd><kwd>метод спектральных отношений</kwd><kwd>метод сдвига центральной частоты</kwd><kwd>соотношение сигнал/помеха</kwd></kwd-group><kwd-group xml:lang="en"><kwd>processing of seismic data</kwd><kwd>methods of q-factor estimation</kwd><kwd>q-factor</kwd><kwd>spectral ratio method</kwd><kwd>frequency pick shift method</kwd><kwd>signal to noise ratio</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Авербух А.Г.
