    • A downhole tool has a tubular body with an end, an exterior wall, and a bore. A mating surface is formed intermediate the exterior wall and the bore in the end of the tubular body. The mating surface is adapted to couple to a second downhole tool and has an integrated circuit. In several embodiments, the integrated circuit is an RFID circuit in communication with a downhole network through an inductive coupler. A tool identification system has surface equipment with RFID interrogating circuitry connected to a protected integrated RFID circuit in a downhole tool string component through a downhole network. A method for identifying a tool in a downhole tool string includes transmitting signals between surface equipment and identification circuitry in the tool through the downhole network.
    • 井下工具具有带有端部,外壁和孔的管状体。 配合表面形成在外壁和管状体的端部中的孔之间。 配合表面适于联接到第二井下工具并具有集成电路。 在几个实施例中,集成电路是通过电感耦合器与井下网络通信的RFID电路。 工具识别系统具有表面设备,其具有RFID询问电路,其通过井下网络连接到井下工具串组件中的受保护的集成RFID电路。 用于识别井下工具串中的工具的方法包括通过井下网络在工具中的表面设备和识别电路之间传输信号。

    • An apparatus and method for discovering and monitoring a collection of nodes in a downhole network may include receiving data packets originating from several downhole nodes. These packets may be read to extract a unique identifier and hop count for each of the nodes. This information may then be used to create entries in a network topology table corresponding to each of the downhole nodes. Each entry may contain unique identifier identifying the respective node, a hop count identifying a location of the node within the downhole network, and a direction identifier. The method may further include modifying one or more entries in the topology table having a conflicting hop count and direction identifier.
    • 用于发现和监测井下网络中的节点集合的装置和方法可以包括接收源自多个井下节点的数据分组。 可以读取这些分组以提取每个节点的唯一标识符和跳数。 然后可以使用该信息来在与每个井下节点相对应的网络拓扑表中创建条目。 每个条目可以包含标识相应节点的唯一标识符,标识井下网络内的节点的位置的跳数和方向标识符。 该方法还可以包括修改具有冲突的跳数和方向标识符的拓扑表中的一个或多个条目。
