摘　　要：压裂微震数据采集具有采样时间长,以及采样间隔小的特点,采集得到的数据量很大。因此数据的读取和显示,需要一些特殊的方法,进而能有效地分析数据中的微震事件。针对微震数据的特点,这里运用LOD(Level of Detail)和内存映射,来实现微震数据快速读取和可视化,为精确反演微震事件奠定了基础。The acquisition of micro-seismic data has some features, including long sampling time and small sampling interval. Therefore, the amount of micro-seismic data is very large. According to the features of micro-seismic data, some special ways are needed to read and to display micro-seicmic data. Meanwhile, they are the foundation of precise inversion of micro-seismic events. In this paper, LOD (Level of Detail) and memory mapping are used to achieve the aim.
