According to the rock resistivity measuring instrument and the measurement method, the data acquisition and analysis can be carried out on a rock sample of which the internal distribution structure has the inhomogeneous anisotropic in the x, y and z three dimensional stereo space, thereby solving the problem that an error caused by the single dimension measurement is larger.
Description
technical field [0001] The invention relates to the technical field of geological exploration electronic measurement, in particular to a rock resistivity measuring instrument and a measuring method. Background technique [0002] The traditional single-dimensional measurement method is to use a measurement probe to perform data measurement and subsequent data processing on a certain dimension of the sample. However, the electrical conductivity of a rock sample is affected by its internal non-uniform anisotropy distribution. Therefore, the resistivity value measured in a single dimension can only represent the resistivity characteristics of the sample in this dimension. [0003] The traditional single-dimensional measurement method is to use a measurement probe to perform data measurement and subsequent data processing on a certain dimension of the sample. [0004] Generally, there are two-electrode method and four-electrode method. [0005] The two-electrode method usually...
