Based on the well seismic characteristics and the combination of forward modeling and actual response characteristics, three types of reservoir assemblage are identified in the Z2dn4 Formation in Hechuan area. Type I reservoir assemblage - the top of the Z2dn4 Formation is the dissolution fracture-cavity type reservoir. The Z2dn4 Formation presents the response characteristics of “top weak and complex wave”. Type II reservoir assemblage -- internal fracture-cavity reservoir is developed, and the Z2dn4 Formation presents the response characteristics of “top strength and internal disturbance”. Type III reservoir assemblage - the reservoir is poorly developed, and the Z2dn4 Formation is characterized by “top strength and narrow trough” response. The quantitative intersection analysis shows that the individual well productivity or reservoir development is inversely proportional to the amplitude and frequency. By using attribute fusion body technology to make the multiplication of amplitude frequency attribute fusion body attribute, the coincidence rate of high quality reservoir of the Z2dn4 Formation reaches 90.4%, which effectively supports the well location deployment of the Z2dn4 Formation in Hechuan area.Keywords: seismic attributes, reservoir characterization, predictive analytics, carbonatePermalink: https://doi.org/10.1190/segam2021-3583369.1FiguresReferencesRelatedDetails First International Meeting for Applied Geoscience & Energy Expanded AbstractsISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2021 Pages: 3561 publication data© 2021 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 01 Sep 2021 CITATION INFORMATION Xubing Chai, Laisheng Cao, Mingfeng Tian, Zhilong Yu, Caijun Jiang, Fenglong Huo, and Shiwei Huang, (2021), "Prediction of carbonate reservoir in platform based on the multiplication of amplitude-frequency attribute fusion body," SEG Technical Program Expanded Abstracts : 1076-1080. https://doi.org/10.1190/segam2021-3583369.1 Plain-Language Summary Keywordsseismic attributesreservoir characterizationpredictive analyticscarbonatePDF DownloadLoading ...
