Pre-stack seismic data thin layer identification method based on two-dimensional Teager-Huang transformation

The invention discloses a pre-stack seismic data thin layer identification method based on two-dimensional Teager-Huang transformation, and relates to the field of oil and gas geophysical prospecting engineering. Comprising the following steps: S1, performing two-dimensional empirical mode operator decomposition on single-channel set data to obtain different scale components; s2, selecting component operators with different scales, and selecting a component with the maximum relevancy with an original signal; s3, carrying out 2D-TKEO operator calculation on the components; s4, carrying out Hilbert transformation on the calculated data to obtain a Hilbert spectrum; s5, superposing the Hilbert spectrum to obtain a time-frequency analysis superposition spectrum; and S6, performing Gaussian smoothing on the superposition spectrum, and extracting a result peak point corresponding to a reservoir interface. By adopting the scheme, the problem of low effectiveness of most thin reservoir positioning identification tech
