Problems solved by technology

[0005] Generators are generally used to provide electric energy for the power supply in the sweeping work of the excitation elevator. Due to the grounding conditions of the power supply points and the shielding effect of the current and other factors, it is difficult to increase the current input to the ground at each power supply point; If the number of electrodes is increased at the same position, it is also difficult to tap the power supply potential of the generator due to the shielding effect of the current

Embodiment Construction

[0016] Refer to the following figure 1 , figure 2 , image 3 The present invention will be further described in combination with specific embodiments.

[0017] suppose as figure 1 The survey area shown is to carry out IP scanning work, and a total of 9 survey lines are arranged in the survey area (the survey line numbers are 0, 4, 8, 12, 16, 20, 24, 28, and 32 lines). There are 11 measuring points on the line (the measuring point numbers on each measuring line are 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20), and each measuring point number includes the measuring line number And the measuring point number, that is, the measuring point number adopts the X-Y pattern (X is the measuring line number, Y is the measuring point number), for example, the number of the measuring point 0 on the measuring line 0 is 0-0, and so on.

[0018] According to the method of IP scanning that a plurality of power supply points supply power at the same time proposed by the present invention, fi...

Abstract

The invention provides an induced polarization (IP) sweeping method with multiple power supply points realizing simultaneous power supply. According to the method, an electric transmitter is utilizedto simultaneously supply power at more than three power supply points at different positions, an electric receiver is utilized to obtain the potential information and the IP information of the measurement points at the different positions in the measurement area, resistivity data of the measurement points at the different positions are obtained through a normalization device coefficient and a resistivity calculation formula of the multiple power supply points realizing simultaneous power supply, and IP sweeping operation of the multiple power supply points realizing simultaneous power supply is achieved. The method is advantaged in that the method helps to expand the horizontal and vertical range of the horizontal electric field, improve signal intensity, expand the IP sweeping range, reduce isolation influence of a power source and increase the amount of geological information of the measuring points of a measuring electrode, and thereby improvement of the IP sweeping effect and sweeping efficiency is achieved.

Description

technical field [0001] The invention relates to an IP scanning method in electrical prospecting. Background technique [0002] At present, the most commonly used scanning method in IP scanning is the scanning method using an intermediate gradient device powered by a pair of power supply points. The intermediate gradient device powered by a pair of power supply points is within the survey line range of the middle 1 / 3AB length between the power supply points AB, and the current field is close to the horizontal electric field within the 1 / 5AB length range of the vertical survey line direction, which is beneficial in Within this measurement range, the exploration target is analyzed and studied to improve the exploration effect and efficiency. [0003] Although the survey efficiency and effect of the intermediate gradient device powered by a pair of power supply points have been significantly improved and improved, it is limited to the range of the middle 1 / 3AB length of the sur...
