发明名称 MULTIPLE TRANSMITTER AND RECEIVER WELL LOGGING DEVICE WITH ERROR CALIBRATION SYSTEM
摘要 A device and method for obtaining an electromagnetic propagation measurement of a subterranean geologic formation, with the formation being intersected by a borehole. The device comprises a transmitter for transmitting an electromagnetic signal, and a first and second receiver for receiving the transmitted signal. The device further comprises a circuit for injecting a calibration signal into the first receiver and the second receiver, and a processor for processing the uncalibrated receiver signal and the calibration signal to obtain electromagnetic propagation measurement that is free from errors introduced by the receiving elements of the system. The processor may include a receiver data acquisition circuit for correcting data acquisition errors related to the first receiver and the second receiver.
