Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1: referring to fig. 1-4, to achieve the above object, the present invention provides the following technical solutions:

a hybrid electric sounding device comprises a receiver and a group of observation electrodes, wherein the group of observation electrodes is formed by M1～The M9 consists of 9 observation electrodes, the B pole of the GDP32 receiver is fixed at a position 1000-3000M away from the centers of the observation electrode groups M1-M9, and the power supply position of the A pole of the GDP32 receiver moves between the observation electrodes M1-M9. Taking the electrical workstation of GDP32 in the united states as an example, a dipole + tripolar + quadrupolar arrangement is constructed on the basis of its multi-channel functions. That is, only one power supply electrode needs to be moved each time, multiple channels of MNs receive simultaneously, and the schematic diagram of the hybrid electric sounding device is shown in fig. 1.

The common electrical depth measurement section can be regarded as a high-density electrical method section with relatively low data density, and in principle, all the depth measurement sections can be processed by using high-density electrical method software. In order to optimize the memory arrangement of the program, the electrodes of the common depth-finding section should be designed on the electrode points of the high-density electrical section. It is generally contemplated that the cross-sectional seam may be positioned at a point on the seam 50m, 40m, 30m, 20m, 10. The distance between the two electrode points closest to each other on the section is called the minimum electrode distance. The larger the minimum electrode distance is, the more effective the computer memory arrangement is, and the faster the inversion speed is.

The B pole is fixed at a position 1000-3000M away from the center of the observation electrode group M1-M9, the A pole starts to supply power from the A1 near M9, the A pole gradually moves towards the An direction to observe M1-M9, and the depth measurement data of the group M1-M9 are observed every time the A pole moves, until the A pole moves to the An position (the A pole is 1000-3000M away from the center of the observation electrode group M1-M9).

Such a hybrid electric depth measurement device corresponds to a combination of tripolar and quadrupole depth measurements, and can be regarded as a tripolar arrangement when the a pole is closer to M1 to M9, and is converted into An asymmetric quadrupole arrangement when the a pole is finally moved to An. The working mode of the hybrid electric sounding device can simplify field work on the premise of not reducing the exploration effect, but increases the complexity of data arrangement. The section resistivity and the polarizability of the hybrid electric sounding device can be calculated in an inversion mode by using data processing software which is compiled by the user.

(2) Data processing format:

the k value of the hybrid electric depth device is calculated by adopting a middle gradient device coefficient formula, and finally, a dat data format is formed as follows:

XXX region XX section depth finding inversion … line name 25 … … minimum electrode distance

11 … … arrangement type (unconventional arrangement = 11)

Sub-permutations of the 0 … … unconventional permutation (all taken to be 0) Type of measurement … Type 0 … … measurement resistivity 300 … data points Total points

Recording location type of 1 … … data point

1 … … data mark of induced polarization (0 = resistivity only, 1= resistivity and polarizability)

89.2 … … … electrode count; the x, z coordinates of the c1 electrode; the x, z coordinates of the c2 electrode; x, z coordinates of the p1 electrode; x, z coordinates of the p2 electrode; the measured apparent resistivity value at the first point, charge rate value … …;

the inversion of the mixed electrical sounding data is different from the conventional quadrupole sounding, model resistivity limitation is required to be added, an expansion model is used, and the result after 3-5 times of iteration is generally taken.

(3) Hybrid electric sounding device model mesh:

high density electrical method profile inversion (including monopole-dipole, tripolar and wenner devices) is usually set as a uniform cross-section model, i.e. model sub-blocks are equal in size, but model data points are inverted trapezoids, and data is missing in deep parts. As shown in fig. 2.

The symmetric quadrupole device is generally provided with a smaller cross-section model subblock in a shallow part, and the model subblock is sparse, namely, a smaller number of deep data points as the pole pitch is enlarged and the deep cross-section model subblock is enlarged. See fig. 3.

The mixed electric deep device model grids are set to be equal section models of shallow parts and unequal section models of deep parts, and sub-blocks of the deep parts are encrypted, namely deep data points are encrypted. See fig. 4.

Embodiment 2, on the basis of embodiment 1, the receiver can also select a GDD multichannel laser in canada, a V8 electric workstation in canada, a WDJS-3 series multichannel digital laser in Chongqing Pentium, and the like.
