Zusammenfassung:The invention discloses a density clustering-based dipole acoustic logging frequency dispersion correction method and a related device. The density clustering-based dipole acoustic logging frequency dispersion correction method comprises the following steps of: performing frequency dispersion analysis on dipole acoustic logging data of a target depth point to obtain a frequency dispersion curve corresponding to the target depth point; repeating the execution until the frequency dispersion curve group of the target layer section is obtained; processing the frequency dispersion curve group by using density clustering to obtain an effective part in the frequency dispersion curve group; and fitting effective parts in the frequency dispersion curve group to obtain a correction result. According to the method, the frequency dispersion curve is clustered and screened by using density clustering, and the training of a large amount of data is not needed in advance, so that the extraction efficiency of effective data i
