摘要
介绍了监测复杂断块油藏水力压裂裂缝扩展规律的三种技术,包括井下微地震测试技术、地面倾斜仪测试技术及地面电位法测试技术,并对方位测试技术的测试原理、应用仪器、测试程序及现场应用进行了细致分析。现场试验表明,在复杂断块油藏依靠数值软件模拟的裂缝扩展规律与实际相差较大,要想较准确认识裂缝扩展规律应该依靠水力裂缝方位测试技术。
Three techniques of monitoring ways of speading of hydraulic fracture of complicated fault reservior are presented in the paper:microseismography;clinometer;potentiometry.Then detail analyses on them are conducted,which leads to the conclusion that testing method of hydraulic fracture orientation is the best method to know ways of fracture speading.
