The invention discloses a three-dimensional numeral
simulation method based on an arbitrary
dipole-
dipole device for a direct-current
induced polarization method. The three-dimensional numeral
simulation method includes the steps of adopting a three-dimensional direct-current
induced polarization arbitrary
dipole-dipole device to carry out all-region observation and parameter measurement; calculating a
specific resistance model of a normalized background
electric field of actually measured data; calculating the normalized transmission functions of the
specific resistance and
polarizability ofthe actually measured data; calculating the normalized transmission functions of the
specific resistance and
polarizability of a theoretical model. According to the method, under complex conditions, all-region observation of three-dimensional numeral
simulation of the three-dimensional direct-current
induced polarization arbitrary dipole-dipole device can be achieved without limitation of null lines of an
electric field, the distribution of electrodes is flexible, and as for an important exploring area, the density of measurement points can be enhanced freely, the method is capable of adaptingto exploration in a complex environment; more abundant three-dimensional information of an underground target body can be obtained, and preparation conditions can be provided for inversion imaging ofeach anisotropic medium; the method has the advantages of being big in morphological difference, abundant in polarization information, high in resolution ratio, and capable of effectively improving the calculation accuracy of numeral simulation.
