High-to-Low Voltage Couplers and Coupling Methods and Sensor-Equipped Electric Submersible Pump Systems |
摘要 |
An electrically powered artificial lift system includes a tubular for conveying a wellbore fluid upward and a downhole pump that urges the wellbore fluid into the tubular. A power cable conveys a three-phase power signal to the pump motor on three conductors. One of the three conductors is coupled to an internal node of a high-to-low voltage (HLV) source coupler via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. A similar downhole coupler couples a wye point of the motor to a downhole sensor assembly to supply the sensor power signal and to receive the telemetry signal. |

1. An electrically powered artificial lift system that comprises:
a tubular for conveying a wellbore fluid upward; a downhole pump that urges the wellbore fluid into the tubular, the downhole pump being driven by a three-phase motor; a cable that conveys a motor power signal to the motor on three conductors; and a high-to-low voltage (HLV) source coupler having an internal node coupled to a selected one of the three conductors via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. |
