Claim 0:
1. A distributed three-dimensional (3D) induced polarization (IP) data acquisition and processing device, comprising:
a transmitter module, a computer and multiple receiver modules, wherein
the transmitter module is configured to transmit a preset current signal to a ground where a region to be measured is located, and record the current signal in real time;
the receiver modules each are configured to acquire a voltage signal and an apparent polarizability of the ground where the region to be measured is located, and record the voltage signal and the apparent polarizability in real time; and
the computer is configured to acquire the current signal, the voltage signal and the apparent polarizability, respectively process the current signal and the voltage signal to obtain an apparent resistivity of the region to be measured, and analyze, according to the apparent polarizability and the apparent resistivity, a polarizability and a conductivity of the region to be measured;
wherein the receiver modules each comprise: a voltage recorder and at least three receiving electrodes, the receiving electrodes each are connected to the ground, and configured to acquire a voltage signal flowing through the ground; and the voltage recorder is connected to each of the receiving electrodes, and configured to acquire the voltage signal and the apparent polarizability of the ground where the region to be measured is located, and record the voltage signal and the apparent polarizability, and
wherein when there are three receiving electrodes, the three receiving electrodes are arranged in an L-shaped distribution.
