High accuracy and high resolution seismic impedance is a prerequisite for subsequent reservoir interpretation. The data-driven approach offers the opportunity for accurate impedance prediction by establishing a nonlinear mapping between seismic data and impedance. However, existing data-driven methods take the raw seismic data directly as input, making it difficult for the network to learn high frequency weak signal information and resulting in low resolution inversion results. In order to mitigate the above issues, a data-driven seismic impedance inversion method based on multi-scale strategy is proposed. The method first obtains seismic data at different scales using frequency division techniques and do normalization on the extracted multi-scale data to ensure the consistency of the seismic signal energy in different frequency bands. The multi-scale seismic data will then be fed into the network, which helps the network to learn the high frequency information features more easily, and ultimately obtain higher resolution inversion results. We use the most commonly used convolutional neural network (CNN) as an example to demonstrate that the proposed multi-scale data-driven seismic impedance inversion method can improve the resolution of the inversion results. In addition, since the above seismic impedance inversion method is executed trace-by-trace, the f-x prediction filtering technique is introduced to improve the lateral continuity of the inversion results and obtain more geologically reliable impedance profiles. The validity of the proposed method is verified in the application of synthetic model data as well as an actual data set.<\/jats:p>","DOI":"10.3390\/rs14236056","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T05:45:22Z","timestamp":1669787122000},"page":"6056","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Data-Driven Seismic Impedance Inversion Based on Multi-Scale Strategy"],"prefix":"10.3390","volume":"14","author":[{"given":"Guang","family":"Zhu","sequence":"first","affiliation":[{"name":"The State Key Laboratory of Petroleum Resources and Prospecting, National Engineering Laboratory for Offshore Oil Exploration, China University of Petroleum (Beijing), Beijing 102249, China"}]},{"given":"Xiaohong","family":"Chen","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Petroleum Resources and Prospecting, National Engineering Laboratory for Offshore Oil Exploration, China University of Petroleum (Beijing), Beijing 102249, China"}]},{"given":"Jingye","family":"Li","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Petroleum Resources and Prospecting, National Engineering Laboratory for Offshore Oil Exploration, China University of Petroleum (Beijing), Beijing 102249, China"}]},{"given":"Kangkang","family":"Guo","sequence":"additional","affiliation":[{"name":"Petroleum Exploration and Production Research Institute, China Petroleum & Chemical Corporation (SINOPEC), Beijing 102206, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"M101","DOI":"10.1190\/geo2014-0546.1","article-title":"Multitrace impedance inversion with lateral constraints","volume":"80","author":"Hamid","year":"2015","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"108296","DOI":"10.1016\/j.petrol.2020.108296","article-title":"Geological structure-guided hybrid MCMC and Bayesian linearized inversion methodology","volume":"199","author":"Zhang","year":"2021","journal-title":"J.
