| 英文摘要 | To locate sources of micro-seismic events, a method based on seismic interferometric traveltime is proposed in this paper. This method builds on the concept of seismic wave-field interferometry. In this method, we define the interferometric traveltime as the difference of traveltimes from one seismic source to other two different receivers. The locations of micro seismic events can be obtained by inverting seismic source's spatial position through iteration to obtain minimum interferometric traveltime residual. We set up a difference objective function to eliminate the seismic origin time in seismic arrival time. It can simplify the micro-seismic locating problem, because it reduces the velocity disturbance's influence on traveltime difference. The examples of the numerical calculation show that this method is stable under the velocity model disturbance, and has the advantage of interferometric locating in the multi-event problem with high accuracy. |
