摘　　要：声发射定位监测裂缝技术通过接受水力压裂时地层裂缝张开及关闭出现的低频音声发射信号,了解声源空间分布,确定裂缝空间形态和地应力分布。在苏里格气田苏A区块气层改造中使用该项技术,完成裂缝、地应力、多次压裂工艺监测,为区块井位部署、水平井轨迹优化、压裂设计优化提供了依据。Acoustic emission monitoring positioning technology can understand the spatial distribution of the sound source to determine the spatial form of crack and stress distribution through accepting the low frequency sound of acoustic emission signals appearing crack's open and close when hydraulic fracture operated. Application of it to gas reservoir at the Su A block in the Sulige gas field,the crack,stress,repeated fracturing process monitoring have been completed which provides the basis for deployment of blocks,optimization of horizontal well trajectory and fracturing design.
