摘要
作为水力压裂监测的最有效手段,微地震监测越来越受到人们的重视,特别是地面微地震监测因为便于施工、观测充分等优点成为研究的热点,然而由于微地震的特殊性,是否能够在地面强噪声环境下接收到有效的微地震事件,成为地面微地震监测整个技术环节的关键点。文中从水力压裂的产生能量、地面压裂车组噪声的干扰情况以及不同深度微地震传播的差异三个方面进行了深入分析,从"信(有效事件)噪(地面噪声)"两个角度,得出了地面微地震可以接收到可靠的压裂信号的结论。在Yan227水平井水力压裂地面微地震采集的实际数据验证了该方法的实用性,为地面微地震技术开展提供了依据。
Micro-seismic monitoring,as the most effective means of hydraulic fracturing monitoring,has attracted more and more attention and is becoming a hot research topic due to its advantages such as easy engineering and full observation. Nevertheless,due to the particularity of microseism,the problem whether valid micro-seismic events could be received under the strongly noisy ground is the key point of the whole technique. In this paper,the author conducted an in-depth research in three aspects,i. e.,the energy conducted by the hydraulic fracturing,the interference situation of fracture truck unit noise and the difference of different depth of micro seismic propagation and,from two angles of " signal(effective events) and noise(surface noise) ",reached the conclusion that surface microseism is capable of receiving reliable fracture signal. The real micro-seismic data acquisition from Yan227 horizontal hydraulic fracturing well verified the effectiveness of this technology,which provides the basis for the implementation of the surface microseismic technology.
