摘要： A method for transmitting signals through a metal tubular includes the steps of transmitting modulated electromagnetic signals through a non magnetic metal section of the metal tubular, detecting the signals or a field associated with the signals, and controlling or monitoring devices or operations associated with the metal tubular responsive to the signals. A material, geometry, treatment, and alloying of the non magnetic metal section are selected to optimize signal transmission therethrough. A system for performing the method includes the metal tubular and the non magnetic metal section. The system can also include a transmitter device configured to move through the metal tubular emitting the electromagnetic signals, an antenna on the outside of the non magnetic metal section configured to detect the electromagnetic signals, and a receiver-control circuit configured to generate control signals responsive to the electromagnetic signals.

摘要： The switching device comprises an electronic switch (111) embedded within a downhole tool (100) and an activator (20) for remote switching of the electronic switch (111). Theactivator (20) may be a handheld unit that is used at the surface of the wellbore by an operator or may be a wireline run unit. The activator (20) permits wireless and contactless activation of the electronic switch (111) without the need for mechanical switches which could provide a point of failure for the downhole tool (100). The electronic switch (111) comprises an electronics module and a power source such as one or more batteries (126) wherein in the active configuration, the switch (111) can allowelectrical connection between the electronics module and the power source (126) and in the inactive configuration, the switch (111) prevents electrical connection between the electronics module and the power source (126).
