By derivation, we know that the positions of eigenvalues of different order derivatives are identical only when the source depth is 0. Based on this characteristic, we propose a potential field source position imaging method based on different order derivatives.By searching for the consistent point of extremum of different orders derivatives in the lower half space obtained by downward continuation, the point position is the source position.Theoretical model tests prove that our method can fast and correctly calculate the position of source ，and have stronger anti-noise capability.Presentation Date: Tuesday, September 17, 2019Session Start Time: 1:50 PMPresentation Time: 3:05 PMLocation: 214DPresentation Type: OralKeywords: 2D, gravity, imaging, edge detection, sourcesPermalink: https://doi.org/10.1190/segam2019-3214319.1FiguresReferencesRelatedDetails 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 Guoqing Ma, Yanbo Ming, and Taihan Wang, (2019), "Potential field source position imaging method based on different order derivative," SEG Technical Program Expanded Abstracts : 1734-1738. https://doi.org/10.1190/segam2019-3214319.1 Plain-Language Summary Keywords2Dgravityimagingedge detectionsourcesPDF DownloadLoading ...
