Она позволяет извлекать из сейсмических данных модель с высоким уровнем детализации, т. е. высокочастотную составляющую модели. При этом входными данными являются результаты временной обработки, а вопросы, связанные с низкочастотной составляющей модели, как правило, не рассматриваются. В представленной работе реализован алгоритм сейсмической инверсии, основанной на модели. Входными данными для инверсии являются результаты глубинной миграции в истинных амплитудах и глубинно-скоростная модель. Численно исследуются возможности сейсмической инверсии для уточнения низкочастотной составляющей модели. Эксперименты проведены с использованием синтетических сейсмических данных, полученных для реалистичной модели Sigsbee.</p></abstract><trans-abstract xml:lang="en"><p>Seismic inversion is used in practice as a tool for predicting reservoir properties. It allows one to extract a model with a high level of detail from seismic data, i.e., high-frequency component of the model. In this case, the input data are the time processing results, and the issues related to the low-frequency component of the model are not considered usually. In the presented work, a model-based seismic inversion algorithm is implemented. The input data for the inversion are the depth image results in true amplitudes and the depth migration velocity model. The possibilities of seismic inversion are numerically investigated to refine the low-frequency component of the model. Experiments were carried out using synthetic seismic data got for realistic Sigsbee model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Cейсмическая инверсия</kwd><kwd>глубинная миграция</kwd><kwd>низкочастотная составляющая модели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Seismic inversion</kwd><kwd>depth migration</kwd><kwd>low-frequency model</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке РФФИ и ЧНФ в рамках научного проекта № 20-55-26003.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The reported study was funded by RFBR and GACR, project number 20-55-26003.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ампилов Ю.П., Барков А.Ю., Яковлев И.В., Филиппова К.Е., Приезжев И.И.
