Abstract

The invention discloses an offset electrical sounding device, comprising an electrical transmitter (F), at least two sets of electrical receiver (V) and an offset processor; wherein the electrical transmitter (F) is used for supplying measuring current, the electrical receiver (V) includes a plurality of measuring electrodes which are parallel to power-supply baselines arranged in an area to be investigated and are arranged with certain reasonable offset distance, and based on the distance between vertical projecting points of the offset distance and an proximal end power-supply electrode to the respective measuring lines and the measuring electrodes, and the distance between two adjacent measuring electrodes (measuring dipoles) which are used for obtaining readings, the offset processor is used for correcting the offsets of data read from the at least two sets of electrical receiver (V), thus obtaining the final corrected measuring reading. The invention also provides an offset electrical sounding method. By utilizing the device and the method, the measuring efficiency can be greatly improved.

Description

technical field

[0001] The invention relates to the field of electrical prospecting, in particular to an offset electrical sounding device, which is used for rapid measurement in electrical prospecting; the invention also provides an offset electrical sounding method. Background technique

[0002] The direct current method is a branch of the electrical prospecting field. Long-term practice has proved that the direct current method is one of the important methods for exploring groundwater resources and various metal mineral resources.

[0003] There are a variety of electrical detection devices in the prior art. The axial measurement method is mainly used for electrical bathymetry measurement, that is, the axis position where the power supply electrode is located (the baseline of the movement of the power supply electrode or the straight line formed by two power supply electrodes) and the position of the survey line where the measurement electrode is located are A straight l...
