Drilling histogram compilation method based on field documentation data and automatic cartographic generalization

Abstract

The invention discloses a drilling histogram compilation method based on field documentation data and automatic cartographic generalization. The drilling histogram compilation method comprises the following technical modules independently used for pre-processing and storing original field data according to the rules of geological documentation and histogram drawing, combining with expertise and well logging explanation result data to carry out knowledge innervation and the cartographic generalization on the histogram, automatically classifying and archiving a comprehensive result, putting the comprehensive result into storage and carrying out user-defined printing and outputting on a result map. When a comprehensive drilling histogram is drawn through the technical system, the integral generation of the histogram can be realized, a working principle that original documentation data supports map frame generation and expert knowledge leads a final achievement can be embodied, contradiction that originally collected data is artificially tampered and industry knowledge innervation can not be carried out is avoided, the workflows of the comparison of geological documentation data and well logging data and the regulation of stratum (rock stratum) boundary line regulation can be simplified, the compilation efficiency of the drilling histogram can be greatly improved, and the drawing of the histogram can be more normative.

Description

technical field [0001] The invention relates to a drilling histogram compiling method based on field catalog data and automatic drawing synthesis, which belongs to field geological data collection geological information technology and geological map computer-aided compiling technology. Background technique [0002] The collection of field geological data is the first important step in the digital construction of mines, and it occupies an important position in the production practice of digital mines. The storage method of the data obtained in the field determines the rationality and convenience of data use, and lays a solid foundation for the later compilation of geological maps. Since the 1980s, there have been many drilling histogram editing software. These editing and drawing software have better effects and higher efficiency, but the data used are mostly processed hierarchical result data, ignoring the direct connection between the original data and histogram drawing, a...

Problems solved by technology

[0005] In order to solve the deficiencies of the prior art, the present invention provides a method for compiling and drawing a histogram of boreholes based on field catalog data and automatic drawing synthesis, which overcomes the separation of layered data and original data in the process of drawing comprehensive histograms of boreholes in the past. The core adjustment process is cumbersome and the data lacks automatic classification and archiving. In order to improve the efficiency of drawing, the content of the original data obtained in the field and its cataloging method are analyzed, and the storage of data is combined with the editing and drawing of maps; A visualization tool for integrated columns when adjusting the core; combined with the drawing process, it provides a complete idea for extracting, filtering, saving and outputting the drawing results
