摘要

本文介绍了微震监测在波兰地质条件下微震事件定位中的应用。对于一个合成微地震事件的定位，采用了地面和井下监测阵列两种采集方法。井下微地震监测是一种记录诱发地震活动的技术，它将接收器放置在靠近处理井的监测井中。在地面监测的情况下，接收器放置在地面。采用概率密度函数确定震源位置。根据已有的分析，认为在抛光条件下，采用井下微震监测是较好的选择。使用该方法定位的事件定位准确，定位的不确定性较低。

Differences between downhole and surface micro-seismic monitoring

The article presents usage of microseismic monitoring for location of microseismic events in polish geological conditions. For location of one synthetic microseismic event, two methods of acquisition were applied: surface and downhole monitoring array. Downhole microseismic monitoring is a technique of recording induced seismicity using receivers placed in the monitoring well near to the treatment well. In case of surface monitoring receivers are placed at the surface. For determination of hypocenter location probability density function was used. Based on provided analysis it is concluded that for polish conditions it is better to use downhole microseismic monitoring. Event located with usage of this technique was located correctly and uncertainty of this location was lower.
