摘　　要：井下微地震监测技术作为监测压裂效果的有效手段之一,首次在长庆油田的庄19井区得到了应用。本文在简要介绍井下微地震压裂监测技术的基础上,论述了选井选层设计、测震传感器的布置优化、井筒体液设计和压裂设计,并利用微地震压裂监测结果分析了压裂井的裂缝展布特征,验证了压裂施工效果。该方法对于验证传统方法的准确性、提高裂缝测试水平及油田开发效果具有重要意义。As one of effective methods of monitoring fracturing effect,downhole microseismic fracture monitoring technique is firstly applied in Zhuang No.19 well area in Changqing Oilfield.This paper introduces mechanism of downhole microseismic technique in hydraulic fracture monitoring and discusses optimization of monitoring well and layer selection,seismic sensors layout, borehole fluid design and fracturing design.Microseismic monitoring data is used to analyze fracture geometry and verify fracturing results.This technique is important in verifying accuracy of traditional method,improving fracture testing level,and improving fracturing techniques and oilfield development.
