WIRELESS DOWNHOLE FEEDTHROUGH SYSTEM |
摘要 |
An apparatus for communicating optical signals between an external device located on a first side of a wellbore barrier and a downhole device located on a second side of the well bore barrier includes a first wireless node which is positioned on the first side of the well bore barrier and is in communication with the external device via a first cable. A second wireless node is positioned on the second side of the well bore barrier and is in communication with the downhole device via a second cable. The first and second wireless nodes are configured to communicate wirelessly through the well bore barrier using near field magnetic induction (NFMI) communications. |
