| 摘 要： | 当微地震事件个数较多时,传统双差定位算法的数据存储量和计算量巨大,难以适应微震震源的定位。提出一种新的微震震源定位算法——混合差定位法。这种算法综合了双差定位算法和Geiger定位法的优点,不仅数据的存储量和计算量大大减小,且与双差定位相比,其定位结果不受初始震源丛的质心位置的影响。模型数据和实际微地震数据测试结果验证了该方法的有效性和实用性。

| Abstract: | When the number of microseismic events is large, traditional double difference algorithm is not suitable for location because of huge amount of data storage. To solve this problem, we propose a new microseismic source localization algorithm-hybrid difference positioning method, which combines the advantages of the double difference algorithm and Geiger positioning method. It not only reduces greatly data storage capacity, but also is insensitive to the initial position of the source. Model data and actual microseismic data verify the validity and practicability of the method. |
