SYSTEM AND METHOD FOR GEOPHYSICAL DATA COLLECTION

摘要

A system and method for geophysical data collection, for use with resistivity and induced polarization. The system and method include the use of a single voltage reference wire to which all voltage recorders or nodes are connected by means of a piercing wire connector, the voltage recorders providing a measurement of the potential voltage between the reference wire and the ground and allowing for calculation of relative voltage potentials between adjacent recorders.

1. A system for use in gathering geophysical data derived from resistivity or induced polarization, the system comprising:
a current transmitter for transmitting current into the ground in an area of interest; a single voltage reference wire for extension within the area of interest; a plurality of voltage recorders spaced apart at respective measurement points along the length of and adjacent to the reference wire; each of the voltage recorders electrically connected to:
a ground-engaging local electrode; anda wire connector; and each of the wire connectors for connecting to the reference wire adjacent the respective voltage recorder; wherein the voltage recorders are configured to measure the potential voltage between the reference wire and the ground at the respective measurement points.
