Wireless two-way communication for downhole tools

摘要

Systems, methods, and devices for two-way communication with a downhole tool string are provided. In one example, a method may include placing a downhole tool string into a pressure riser of a well while at least one component of the downhole tool string is not activated. Thereafter, a wireless control signal may be issued through the pressure riser to the downhole tool to cause the downhole tool string to activate the component. The wireless control signal may involve an acoustic signal, an optical signal, and/or an electromagnetic signal such as electrical dipole coupling or magnetic dipole coupling.

1. A method comprising:
placing a downhole tool string into a pressure riser of a well while at least one component of the downhole tool string is not activated; and issuing a wireless control signal through the pressure riser to the downhole tool to cause the downhole tool string to activate the at least one component; wherein the wireless control signal is issued through the pressure riser via magnetic dipole coupling and wherein the wireless control signal comprises a signal-to-noise ratio of greater than or equal to 11.6 dB.
