Single well microseism monitoring method, storage medium and terminal equipment

The invention discloses a single-well microseism monitoring method, a storage medium and terminal equipment, and the method comprises the steps: updating a speed model through a perforation with a known position, positioning surrounding microseism events through a relative positioning method, taking the microseism events as pseudo main events, updating the speed model again, positioning more micro-seismic events according to the re-corrected speed model and the main event positioning method, further re-correcting the speed model, continuously iteratively circulating the above process, continuously updating the precision of the speed model, and finally, obtaining a relatively accurate speed model, and monitoring the microseism event in the research area based on the accurate speed model. According to the method, not only is a small number of perforations utilized, but also the precision of the speed model is continuously improved by utilizing microseism events generated in the hydraulic fracturing process.
