Method and device for calculating isoline name of geological structure map

Abstract

The invention provides a method and device for calculating the isoline name of a geological structure map. The method comprises: step one, opening a geological structure map graph and setting an isoline name of the geological structure map graph to be plane representation of the value and altitude attribute of the isoline; step two, receiving an adjusting operation for a reference plane of the geological structure map graph by the user; and S3, according to the adjusting operation for the reference plane, carrying out corresponding computing operation on the isoline name of the geological structure map. According to the invention, several kinds of operation modes of modifying the isoline name and supporting the isoline name are realized by a computing mode; automatic modification and batched processing of the isoline names are realized by a computing way; and the simplification and high efficiency of treatment of the complicated problems are realized.

Description

technical field [0001] The invention relates to the technical field of geological structure map analysis, in particular to a method and device for calculating contour names of geological structure maps. Background technique [0002] In the field of petroleum exploration and development, it is necessary to draw various geological structure graphics such as isochronous maps, isobath maps, and topographic maps for the study and preservation of stratigraphic plane features. (Standard layer) Plane projection of the undulating shape of the layer has the advantage of reflecting the underground structure at a glance. The contour data includes a curve and the name of the curve. Usually, the contour is a smooth and continuous curve, and a certain value is given in the middle. A height value is used to indicate the elevation of the contour line, that is, the depth value (Z value) of the contour line. Taking the structural map as an example, it indicates that the undulating shape of a c...

[0003] figure 1 For the existing method of computing contour names, there are two methods to realize the computing of graphic contour names: 1) carry out single and one-by-one name modification, and cannot carry out batch calculation processing to all contour names; 2) Store the contour information to an external program, calculate it in the external program and then re-map

[0004] The disadvantages of the existing contour name calculation methods are: 1) manually modify the contour names one by one, the contour is complex, the workload is large, it is easy to label mistakes, and the work efficiency is reduced; 2) the contour information is stored externally The program re-maps and repeats back and forth, increasing the workload
