The invention provides a rock burst migration identification method based on a Weibull hybrid model, and relates to the technical field of coal mine safety, and the method comprises the steps: obtaining historical micro-seismic monitoring data of any reference coal mine, and constructing a corresponding reference anomaly identification model which is used for determining the anomaly probability of any reference coal mine; target micro-seismic data of the target coal mine are obtained, the target micro-seismic data are mapped to any reference anomaly identification model, a target data set corresponding to the target micro-seismic data is obtained, and the target data set comprises multiple target samples corresponding to the target micro-seismic data; and obtaining an abnormal probability of the target sample in any reference abnormal identification model, and determining whether the target micro-seismic data is abnormal based on the abnormal probability. The problem of constructing a coal mine micro-seismic anomaly identification model under the conditions of insufficient micro-seismic data and unmarked data is solved, and the micro-seismic anomaly state identification capability is improved.

The application provides a velocity model updating method and device based on seismic-logging data difference, which comprises the following steps: obtaining seismic data and logging data; synthesizing model seismic data according to the logging data; calculating the local similarity of the model seismic data and the seismic data by using the LSIM method to obtain a time offset; generating updated logging velocity according to the time offset and logging velocity in the logging data; obtaining initial seismic migration velocity; and generating updated seismic migration velocity according to the logging velocity, the updated logging velocity and the initial seismic migration velocity. The application quantifies misplacement and updates seismic migration velocity by using the local similarity technology, realizes high precision and geological consistency of the velocity model, improves the resolution of the velocity model, and helps to solve the velocity model construction problem in complex strata or anisotropic regions, and has a wide application prospect.
