Interpreting microseismic events triggered by reservoir stimulation (especially hydraulic fracturing) has become a common practice to understand fracture dimension and geometry. In this area of study, the need for accuracy and resolution of microseismic data is relatively high since the object of investigation is relatively small compared to other seismological studies. Hence, a robust tool is necessary to assure the quality of microseismic event locations and support the interpretation. To achieve these primary objectives, we performed a waveform clustering workflow that analyzes all waveforms representing a microseismic event. Using this approach, we identified multiplets suggesting events that are closely located and originated from the same source mechanism. We tested the workflow on microseismic data from coalbed methane stimulation. The method increases our confident on using the dataset for interpretation especially since the monitoring survey is limited by a single borehole array with very minimal spatial coverage.

多通道波形聚类：煤层气激发引起的微地震多重峰

解释由储层增产（尤其是水力压裂）触发的微地震事件，已成为了解裂缝尺寸和几何形状的一种普遍做法。在这一研究领域，由于与其他地震学研究相比，调查对象相对较小，因此对微地震数据的准确性和分辨率的需求相对较高。因此，必须有一个强大的工具来确保微地震事件位置的质量并支持解释。为了实现这些主要目标，我们执行了波形聚类工作流，该工作流分析了代表微地震事件的所有波形。使用这种方法，我们确定了多重事件，这些事件暗示了事件的定位和起源是相同的。我们测试了来自煤层气增产的微震数据的工作流程。
