地震监测钻井设计及工艺研究

摘要
采用井下地震仪可监测到许多地面地震台未记录到的微弱地震波;井下地层形变观测可以摆脱地表的天然及人为干扰,使观测数据更加真实地反应地层变化情况,可大幅度提高震源定位精度。本文结合实际工程对地震监测井的设计、钻井和固井的工艺技术进行了分析研究。针对地震监测井的特殊要求,采用了钻井综合防斜保直技术和分层注浆固井新工艺,使所建地震监测井的垂直度和固井质量都达到了优良,为获取精准的地震监测数椐提供了基本保障。
The down-hole seismograph can monitor lots of weak earthquake waves that can not be recorded by ground seismographs.The down-hole strata deformation observation can avoid natural and human disturbances on the surface of the earth,which allows observational data to reflect truly strata changes,and greatly improves the source location accuracy.In this work,combined with practical engineering,the design of earthquake monitoring wells,drilling and cementing technology were analyzed.According to the special requirements of earthquake monitoring wells,the technology of preventing borehole deviation and the new craft of layered grouting cement were adopted during the drilling,making the perpendicularity of the earthquake monitoring wells and cementing quality both be excellent,which provides a basic guarantee to obtain accurate earthquake monitoring data.
