微地震法在煤层气井人工裂缝监测中的应用

Application of Surface Micro-seismic Method in Monitoring CBM Well Artifical Factures

煤层气井人工裂缝在煤层气开发中起着重要的作用,本文阐述了煤层气井人工裂缝监测原理,通过对人工裂缝监测现场试验及研究分析,为煤层气井压裂效果研究找到了一条科学方法,从而为煤层气地面开发井网布置提供了科学依据。

Artifical fractures for CBM wells play important roles in CBM development. The paper has not only set forth the monitoring principle of artifical fractures for CBM wells, but also established a way of improving fractured resuhs through field tests and analysis, thus providing the scientific basis for arrangement of surface CBM well network.
