    • A data communication system for use in downhole applications wherein electrical energy is supplied over a multiple-conductor power cable to an ESP motor assembly. A downhole unit is AC-coupled to the conductors of the power cable through the wye point of the ESP motor assembly. A surface unit is AC-coupled to the conductors of the power cable. Uplink communication of telemetry data occurs over an AC communication scheme supported by the downhole unit and the surface unit. Downlink communication of remote control command data occurs over a different AC communication scheme supported by the surface unit and the downhole unit. These AC communication schemes provide an independent supply of power to the downhole environment. All communication between the surface and downhole environment is accomplished through the power cable without the use of additional communication lines. Data communication is maintained in the event of a ground fault on the power cable.
    • 一种用于井下应用的数据通信系统,其中电能通过多导体电力电缆提供给ESP电动机组件。 井下单元通过ESP电机组件的摆动点与电力电缆的导体交流耦合。 表面单元与电力电缆的导体交流耦合。 遥测数据的上行通信通过井下单元和地面单元支持的交流通信方案进行。 远程控制命令数据的下行链路通信由表面单元和井下单元支持的不同AC通信方案进行。 这些交流通信方案为井下环境提供独立的电力供应。 表面和井下环境之间的所有通信都是通过电力电缆实现的,而不需要额外的通信线路。 在电源线上出现接地故障时,可以保持数据通信。

    • At least one three phase driven pumps (56) in a hydrocarbon well (10) well bore (12) uses frequency shift keyed digital signals (78) to pass instructions from a surface station (46, 26, 34, 30) to a tool (14, 76, 56) and reports from a tool (14, 76, 56) to the surface station (46, 26, 34, 30) in common mode through the three phase cables (16) using a star point (58) of the three phase cables (16) after each pump as the signal transmission and reception point and as the point for coupling a DC Power supply (28), also provided in common mode on the three phase cables (16), to the down hole electronic equipment (72 76). The surface equipment (46) and the tool (14) use as a common ground. The digital messages comprises an address portion (80) identifying either the tool (14) for which an instruction (82) is destined or the tool (14) from which a report (also 82) originates. The digital message (18) also comprises a checksum (84) for error identification and correction.
