井中微震监测资料处理解释方法应用研究

The Application of the Method of Processing and Interpretation for Micro-seismic Monitoring Data in Wells

微震监测是一种有效的裂缝监测技术,与其他裂缝监测方法相比,监测结果准确,信息丰富。随着非常规油气藏的开采,微震监测技术得到更多的运用,本文针对井中微震资料处理流程和震源定位方法进行研究,以提高定位精度,得到一套行之有效的微震资料处理流程。基于理论模型试算,验证了采用微震事件的走时反演能较好地确定微震位置。该方法应用于河南油田泌阳凹陷某井中微震事件的资料处理解释中,取得了良好的应用效果。

Micro-seismic monitoring is an effective crack monitoring method.It has more accurate monitoring results and provides more information.With the exploitation of unconventional reservoir,micro-seismic monitoring technology will be used more frequency.In order to improve the positioning accuracy,the data processing and location methods have been developed in this paper.An effective data about processing flow have been obtained.The hypocentral location can be determined by travel time inversion for micro-seismic events based on the model trial.This method has been applied to an actual micro-seismic monitoring data processing which is acquired in Bi Yang depressed area by The Henan oil field branch,and has achieved a good application effect.
