The preliminary results are encouraging: Compared with the conventional seismic data acquisition, the PSTM seismic data acquired by this time have higher fold and higher s/n ratio, while the coaxial lateral continuity of deep seismic data is better, and the vertical wave group relationship is clearer. It shows that the application of offshore dual-source random shooting seismic exploration technology can greatly improve the quality of Paleogene data, and provide help for the breakthrough of Paleogene exploration and hydrocarbon evaluation.Presentation Date: Wednesday, September 18, 2019Session Start Time: 1:50 PMPresentation Time: 1:50 PMLocation: Poster Station 12Presentation Type: PosterKeywords: 3D, acquisition, air gun, illumination, processingPermalink: https://doi.org/10.1190/segam2019-3205284.1FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2019ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2019 Pages: 5407 publication data© 2019 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 10 Aug 2019 CITATION INFORMATION Zhang Zhenbo, Luo Wei, Zeng Ting, and Deng Yong, (2019), "The first marine seismic survey of dual-source random shooting offshore China," SEG Technical Program Expanded Abstracts : 288-292. https://doi.org/10.1190/segam2019-3205284.1 Plain-Language Summary Keywords3Dacquisitionair gunilluminationprocessingPDF DownloadLoading ...
