进行地下作业时用于分析地层特性的方法和系统

Methods and systems for analyzing formation properties when performing subterranean operations

Abstract

公开一种用于分析地下地层的方法。从发射机把第一信号发射到地层,并且接收第二信号,第二信号是第一信号的反射。然后把第三信号发射到地层,第三信号是时间反演的第二信号。然后接收和监测第四信号,第四信号是来自地层的第三信号的反射。
A method of analyzing a subterranean formation is disclosed. A first signal is transmitted from a transmitter to the formation and a second signal which is a reflection of the first signal is received. A third signal, which is the second signal reversed in time, is then transmitted to the formation. A fourth signal which is a reflection of the third signal from the formation is then received and monitored.
