摘要： A method, a non-transitory computer-readable medium, and a computing system are provided for determining a telemetry mode of a signal. A drilling telemetry signal is received from a downhole tool in a wellbore. A transformation is determined based at least partially upon the drilling telemetry signal. Multiple features are extracted based at least partially upon the transformation. A decision region is identified based at least partially upon the features. A telemetry parameter is identified based at least partially upon the decision region. A telemetry mode of the drilling telemetry signal is determined based at least partially upon the telemetry parameter. The drilling telemetry signal is decoded based at least partially upon the telemetry mode.

摘要： A method for predicting a telemetry mode of a downhole tool includes receiving a signal from the downhole tool at a computing system at a surface. The method also includes predicting the telemetry mode of the downhole tool based on the signal. The method also includes switching a telemetry mode of the computing system to match the telemetry mode of the downhole tool. The method also includes demodulating the signal using the computing system after the telemetry mode of the computing system has been switched.

摘要： A system and method for downhole signal enhancement. The system includes a downhole tool having one or more sensors coupled thereto. The one or more sensors may measure internal pressure and one or more parameters selected from the group consisting of external pressure, pressure sensor temperature, weight on bit, torque on bit, bending moment, roll gyro, tangential acceleration, radial acceleration, and axial acceleration. A noise estimator may be coupled to the downhole tool and estimate a downhole noise component in the one or more parameters. A telemetry modulator may be coupled to the downhole tool and generate a signal that includes the estimated downhole noise component and a telemetry component. The downhole noise component in the signal may be reduced based at least partially upon the estimate.

摘要： A method includes receiving a signal having a telemetry portion and a noise portion. The method may also include identifying one or more harmonic frequencies in the signal. The method may also include determining whether the one or more harmonic frequencies are in a predetermined frequency band. The method may also include determining whether a signal-to-noise ratio (SNR) of the signal is below a predetermined SNR threshold. The method may also include generating one or more notifications in response to the determination whether the one or more harmonic frequencies are in the predetermined frequency band and the determination whether the SNR is below the predetermined SNR threshold.

摘要： Methods, computing systems, and computer-readable media for detecting sensor malfunctioning status. The method includes receiving sensor measurements of a first type from a first type of sensor, deriving a first value for a metric from the sensor measurements of the first type, receiving sensor measurements of a second type from a second type of sensor, wherein the second measurements of the second type include a second value for the metric, comparing the first value to the second value, determining whether the first type of sensor or the second type of sensor is malfunctioning based on the comparing, and storing or outputting information indicating whether first type of sensor and the second type of sensor are malfunctioning.
