Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0016] see figure 1 , a method for outputting a geological section of a three-dimensional geological model, comprising the following steps:

[0017] Step 1. Stratigraphic marking: materialize the various layers of the geological model in CATIA software, attach different colors, and then use the attribute of color to mark the stratum and structural planes. The geological model constructed by conventional methods is composed of grid surfaces ( That is, the ground plane) and the mesh body, and the lines cut out by the mesh plane and the mesh body are all white, so the stratum cannot be marked. In this step, through the automatic surface command in the CATIA software, the ground plane is materialized and colored.

[0018] Step 2. Create a section: Secondary developm...

Abstract

The invention discloses a geological section output method of a three-dimensional geological model. The method comprises the following steps that (1) a stratum is marked, wherein all stratum surfaces of the geological model are subjected to substantiation in three-dimensional modeling software, and the stratum surfaces and a structural surface are marked with different colors; (2) a section is set up, wherein two points on the geological model are clicked, the original location and the length of the section are calculated through the three-dimensional modeling software, and a sectioning auxiliary surface is generated; (3) a chart ratio is made, wherein the distance between the two end points of the sectioning auxiliary surface is calculated through programming, the obtained distance is compared with the actual distance between the two end points of the actual sectioning auxiliary surface to obtain the chart ratio, and a sectioning auxiliary chart is drawn according to the ratio; (4) a coordinate axis is established; (5) drilled hole projection is carried out, wherein drilled holes near the sectioning auxiliary surface are selected and projected to the sectioning auxiliary surface, information of drilled holes on the periphery of the geological model are recognized and reflected on the sectioning auxiliary surface, and projection holes are drawn; (6) a geological section map is output. The geological section output method solves the problem that drawing work efficiency of a traditional flat section is low, and can be widely applied to the field of three-dimensional emulation techniques.

Description

technical field [0001] The invention relates to the technical field of three-dimensional simulation, in particular to a method for outputting geological sections of three-dimensional geological models. Background technique [0002] Three-dimensional geological modeling based on CATIA software has been used in the industry for many years, and the modeling technology is becoming more and more mature. At present, due to the relatively lagging industry standards for 3D mapping, 3D geological modeling has not been fully promoted, and engineers and technicians still maintain the previous drawing habits, which require a lot of time and energy to draw geological plane profiles. On the basis of creating a 3D geological model based on CATIA, the output of a 2D profile can be realized through the own functions of the CATIA software, but the direct output is not a standardized geological profile, which still needs to be further supplemented and improved. Therefore, how to quickly outpu...
