Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Borehole histogram is a comprehensive map prepared to describe the stratum, thickness, lithology, structural structure and contact relationship of the borehole through the rock formation, groundwater sampling and testing, borehole structure and drilling, etc. The intelligent process starts from paper drilling drawings, and consists of three steps from the standardization of drilling data to the real-time update of geological 3D modeling. It can realize 3D geological modeling without manual operation, and integrate geological knowledge into the intelligently generated geological data. The mod...

Abstract

The invention discloses an efficient three-dimensional geological modeling intelligent processing method based on paper drilling, and the method comprises the following steps: 1, scanning a paper drilling histogram through a table recognition method, carrying out unified filing of the paper drilling histogram into an image and text data, and recognizing each piece of table data; 2, summarizing a geological standard stratum table through machine learning, uniformly importing drilling data into a drilling standard database according to a table, reading drilling data point cloud from the drillingstandard database, and generating a geological surface according to a certain rule connection line; and 3, fusing geological knowledge can into a profile map intercepted by the model, processing stratum culling, modifying and correcting improper places and synchronizing drilling data and changes of connecting lines of the drilling data to the geological model in real time. According to the processing method, errors generated by manual processing can be reduced, risks are reduced, and the efficiency and accuracy of the whole process are improved.

Description

technical field [0001] The invention relates to the technical field of geological information processing, [0002] In particular, the present invention relates to an efficient intelligent processing method for three-dimensional geological modeling based on paper boreholes. Background technique [0003] The 3D modeling of urban geology based on paper borehole data, in the past practical production, it is necessary to manually sort out the data from paper documents to complete the extraction of borehole information. Due to the diversity of borehole sources and the different standards for stratum and lithology classification, before the borehole data can be used for 3D geological modeling, it is first necessary to formulate a standard stratigraphic comparison table according to the geological conditions of the area. Even if the borehole data is standardized according to the table and interpolated based on the stratum boundary points revealed by the borehole, the resulting geom...
