| RGB Plotting Technique Based on Matching Pursuit Algorithm and Its Application to Channel Characterization |
| The exact and efficient acquisition of frequency information of seismic data is the key to the time-frequency technique. Compared with common wavelet transform and generalized S transform method, the matching pursuit algorithm can obtain precise position both in time and frequency domain because of its higher time-frequency resolution and local adaptability. The accurate information of frequency domain can help to do seismic attributes and hydrocarbon detection work. RGB plot is a display technique, which divides several frequency data into lower frequency, middle frequency and higher frequency data, with the display fused by red, green, and blue. This technique can reflect information of various bands, which avoids the less information of a single attribute. In practical application, RGB plot by matching pursuit algorithm is used to depict the channel boundary and characterize the heterogeneity of inner channel to a certain degree, which has profound significance in comparison with common attribute. |
