CPC G01V 1/303 (2013.01) [G01V 1/282 (2013.01); G01V 1/345 (2013.01); G01V 2210/6222 (2013.01)] | 9 Claims |
1. An interpretive-guided velocity modeling seismic imaging method, comprising:
configuring a computing device having one or more processors and a memory, the memory storing program instructions executed by the one or more processors for:
performing first imaging on a given initial velocity model to obtain a first imaging result;
performing relative wave impedance inversion on the first imaging result to obtain a relative wave impedance profile;
performing Curvelet filtering on the relative wave impedance profile to obtain a first interpretation scheme;
superposing the first interpretation scheme and the given initial velocity model to obtain a new migration velocity field;
performing second imaging on the new migration velocity field to obtain a second imaging result; and
repeating the steps of relative wave impedance inversion and Curvelet filtering for the obtained second imaging result until a final seismic imaging result is obtained, the final seismic imaging result is a clear image of a real geological structure.
