AEO - 4A 裂缝监测技术可对水力压裂施工井或高压注水井实施同步裂缝监测。利用岩石张裂时发出的声波在岩石中的传播原理,可准确测出裂缝的形态方位和延伸长度。主要介绍了AEO - 4A 裂缝监测技术的监测原理、应用范围及声波信号的录取方法。以子寅油田仑16 块16 - 27 压裂井实测结果为例,进行了测试结果分析,并提出了新建议。

Synchronous monitor crack of hydraulic fracturing well or high pressure water injection well is practiced by crack monitor instrument , AEO-4A. Making use of the principle that the sonic wave made by the rock open fracture spread in the rock , can accurately test the crack’s appearance directions and extend length. Primarily introduced the crack monitoring principle , the application limit and sonic wave signal record method. As an example , the measured result of Lun 16-27 well , Ziyin Oilfield is analysed , and new proposals are suggested.
