The invention discloses a three-dimensional
conversion method for a two-dimensional geological profile map, and the method comprises the steps: S100, data obtaining and preprocessing: obtaining an original geological profile map, carrying out the format conversion of the original geological profile map, eliminating overlapped line segments and micro short line segments, and maintaining the
topological consistency; s200, conversion parameter calculation is conducted, specifically, drilling coordinates are obtained, and a conversion script is compiled based on the real geodetic coordinates, the two-dimensional profile map coordinates and the
azimuth angle; and S300, conversion execution: reading the map subjected to format conversion in the S100 into three-
dimensional modeling software, and executing the script language compiled in the S200 to obtain a three-dimensional geological profile map. According to the method, the whole file is converted, the conversion from the two-dimensional geological
prospecting line section to the three-dimensional
geological section map can be rapidly and integrally completed through the existing
software technology and simple script codes so as to be used for three-dimensional geological modeling, a large amount of manpower and
material resources can be effectively saved, and the production efficiency can be improved.
