METHOD FOR DETERMINING GEOLOGICAL TYPE

Disclosed is a method for determining a geological type. The method includes: determining a plurality of actual measuring points and actual measuring lines of a target stratum; acquiring actual data of each actual measuring line; determining device coefficients and apparent resistivity corresponding to the actual measuring points according to the actual data; acquiring quality detecting data corresponding to quality detecting lines; determining the device coefficients of the actual measuring points, and determining apparent resistivity of the quality detecting points according to the updated device coefficients, emission currents and potential differences; and generating a quality detecting data summary file, an actual data total file and a quality detecting summary total file based on the actual data and the quality detecting data, so as to determine a geological type of the target stratum.
