微地震震源定位中目标函数的研究与应用

Study and application of objective function in microseismic source location

    摘要
  • 摘要: 针对常规微地震震源定位中走时目标函数的多解性问题,基于三分量微地震数据,建立了联合走时和三分量微震数据方位信息的矢量目标函数,把矢量目标函数运用于Geiger定位方法中,得到了改进的Geiger定位法。模型数据测试表明:该方法对震源的方位信息敏感,定位精度更高。

     

    Abstract: In order to overcome the multi-solution of microseismic source location using time-dependent objective function, for three-component microseismic data, we established a vector objective function combining travel time and azimuths. Applying the objective function to Geiger's method for location, an improved Geiger's method for location is introduced. Synthetic data verifies that the method is sensitive to azimuths and is more accurate.
