Electromagnetic assessment of multiple conductive tubulars |
摘要 |
Systems, apparatuses, and methods for measuring material thickness of multiple tubulars by placing a logging tool in a well with multiple conductive tubulars and generating an electromagnetic field that interacts with the tubulars. A logging tool obtains the measurements using one or more receivers. A monitoring system or the logging tool applies the measurements to a mathematical model that considers at least a transition zone and one or both of a near field zone and a remote field zone of the electromagnetic field that interacts with the multiple conductive tubulars. Furthermore, the monitoring system or the logging tool may ascertain a thickness of the one or more conductive tubulars using the mathematical model. |
