The multiples are related with the high impedance reflection interfaces which caused by the sedimentary environment changes such as depositional break, parallel unconformity and coal beds. In this paper, a case of suppression for interbed mutilples caused by coal beds in Junggar basin was presented. The extended SRME method was used to predict the interbed multiple models and then the multiples were subtracted from the input data using adaptive subtraction technique. After multiples removal, the image of the stratigraphic interfaces below the coal beds is clearer and the fan delta deposition phenomena was interpreted more accurately.Presentation Date: Tuesday, October 13, 2020Session Start Time: 9:20 AMPresentation Time: 11:25 AMLocation: Poster Station 13Presentation Type: PosterKeywords: multiples, internal multiples, adaptive subtractionPermalink: https://doi.org/10.1190/segam2020-3426149.1FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2020ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2020 Pages: 3887 publication data© 2020 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 30 Sep 2020 CITATION INFORMATION Li Daoshan, Yang Huidong, Luo Wenshan, Cao Mengqi, Qi Jun, and Ning Bin, (2020), "Interbed multiple suppression on land data with coal bed in western China," SEG Technical Program Expanded Abstracts : 3229-3233. https://doi.org/10.1190/segam2020-3426149.1 Plain-Language Summary Keywordsmultiplesinternal multiplesadaptive subtractionPDF DownloadLoading ...
