A method to research the properties of Earth formations surrounding a Borehole probe

摘要

Method and apparatus of Recording to investigate the properties of Earth formations surrounding a Borehole probe.The Method comprises the following steps: First, we introduce an electrically Conductive Body, generally tubular in the well; Second, is generated in a Transmitter site on the body, electromagnetic energy that has basically components of the transverse Magnetic mode Q EU are guided by that body; and finally,Are the components of the transverse Magnetic Mode of electromagnetic energy at a receptor site on the body.
