Abstract
The present application provides an underground reservoir monitoring system for real-time monitoring changes of reservoir parameters. The system measures the alternating current signal when an alternating current passes through the transceiver along the casing, and calculates the alternating current flow parameters including phase velocity, group velocity, time difference, amplitude attenuation, and phase difference of the alternating current along the casing based on the alternating current signal. Each alternating current flowing parameter has a one-to-one relationship with the reservoir parameter. Using these relationships, reservoir parameters are calculated and used to monitor changes of the reservoir parameters.
