摘要

国外经过多年多次试验确立了水力压裂诱生微地震井中监测方法,我国刚开始应用此项技术,而应用比较多的是在地面进行监测。根据20世纪90年代以来,典型微地震压裂监测试验成果、井中微地震压裂监测实例及有关的技术试验史料分析认为,微地震压裂监测应在井中进行。同时还进一步分析了地面监测不到高信噪比、高分辨率、高保真度诱生微地震波的原因,并建议引进和发展井中微地震压裂监测技术、地面测斜仪压裂监测技术和电位法水力压裂监测技术。
Inner well monitoring methods for hydraulic fracturing inducing microseismic have been proved by many tests through many years in foreign countries,this kind of methodology just appeared in our country for a short time,and are mostly applied above ground.Since 1990s,the analysis of the typical microseismic fracture monitoring tests achievements,inner well cases and related technology tests data shows that this methodology should be carried out in wells.Furthermore,the article pointed out the reasons for why monitoring above ground will not get an induced microseismic wave with high signal-to-noise ratio,high resolution and high fidelity.The suggestion of introducing and developing inner well microseismic fracture monitoring technology is proposed in the article as well.
