Background technology
There are symmetrical four-pole sounding, dipole-dipole depth measurement and middle terraced section bathymetry etc. in two-dimentional electrical prospecting at present.
Symmetrical four-pole sounding method arranges that approximate log is powered at equal intervals away from the two-dimentional electrical method of realization using each measurement point
Explore depth measurement, the advantages of this method is symmetrical powering pole of each measurement point arrangement relative to measurement point, and measuring electrode away from
From control less than 1/3 polar distance of supplying power, realize that level field trend is presented in measurement point measuring signal, GEOLOGICAL INTERPRETATION is simple.But due to
Each measurement point is required to arrange a series of supply terminals, often arranges a series of supply terminals, is only capable of measuring single measurement point, therefore works
Efficiency is too low.Assuming that a certain exploration line arranges n symmetrical quadrupole measurement point, according to the single measurement of symmetrical quadrupole shown in table 1
Point polar distance of supplying power and measuring electrode are arranged away from parameter list, then in order to complete the depth measurement of all measurement points work, need arrangement 16 × 2

The depth of exploration of bigger is only realized by increasing the power of electric power system, and will cause electric power system heavy in this way, is reduced
Exploration efficiency.
The pattern of terraced section during middle ladder section bathymetry borrows realizes depth measurement by the size of polar distance of supplying power terraced in change
Purpose, this method terraced depth measurement pattern in measuring the work of the depth measurement other than point range and using for supply terminals, can realize exploration effect
The raising of rate, but this method uses the symmetrical quadrupole of small pole span to each for depth measurement work of the supply terminals in the range of measurement point
The electric signal of measurement point measures, so as to cause the electrical prospecting needed to two methods of each measurement point development, although energy
The depth measurement workload of big pole span is reduced, but increases the workload of small pole span.
