水力压裂诱发地震研究进展

Research Progress of Hydraulic Fracturing Induced Earthquake

随着近年来页岩气水力压裂技术的普及,该技术诱发的地震活动也引起了全世界的广泛关注。四川盆地作为开采中国页岩气的主要区域之一,自2015年水力压裂技术在盆地内全面推进,地震活动频度和震级均呈增长趋势。本文通过收集和分析全球水力压裂诱发的地震,尤其是四川盆地区域的地震,从地震活动的现象和特征、可能诱发机制、地震监测、风险减轻、灾害预测等方面进行了较为全面的阐述,对全面认识水力压裂诱发地震具有一定的参考价值。

In recent years,the popularity of hydraulic fracturing technology inducing seismicity it has attracted wide attention all over the world.Since the comprehensive promotion of hydraulic fracturing technology in 2015,as one of the main areas of shale gas exploitation in China,Sichuan Basin has an increasing trend in the frequency and magnitude of seismic activity.We collect the data of global earthquakes induced hydraulic fracturing,especially in Sichuan Basin,to expound the seismicity characteristics,inducing mechanism,earthquake monitoring,risk mitigation,disaster prediction of induced earthquakes,which have certain value of reference to the comprehensive understanding of hydraulic fracturing induced earthquakes.
