3D Visual Modeling Method of Coal Measures Bearing or Water-resisting Layer

Abstract

The invention discloses a three-dimensional visualization modeling method of a coal-bearing or water-resisting layer, which includes: preparing basic data for research; establishing a corresponding fault model based on a digital structural map and breakpoint data; and dividing the aquifer and the water-resisting layer , identify the corresponding aquitard or aquitard interface, establish the stratigraphic framework of the aquitard or aquitard, establish the corresponding layer model by Kriging interpolation method; Establish sedimentary microfacies model based on the technology of facies distribution characteristics; based on facies control technology and theory, establish physical property model of aquifer according to collected and calculated physical property data; show coal-bearing or water-resistant strata according to the final related model The spatial distribution law of . The invention uses modeling to describe the spatial distribution of the aquitard or aquitard objectively, intuitively reflects the three-dimensional spatial distribution of the aquitard or the aquifer's water-rich characteristics, and provides a three-dimensional visualization for the study of the coal-bearing or aquitard. in accordance with.

Description

technical field [0001] The invention relates to a method for three-dimensional spatial distribution of a coal measure containing or water-resistant layer, in particular to a three-dimensional visualization modeling method for a coal measure containing or water-resistant layer. Background technique [0002] my country's coal production and consumption ranks among the top in the world, and coal plays a pivotal role in domestic energy consumption. With the increase of mine mining depth and intensity, mine water disasters occur more and more frequently. It is particularly important to find out the hydrogeological conditions of coal mines and study the distribution of aquifers intuitively. [0003] In the traditional study of coal-bearing or water-resisting strata, two-dimensional geological maps are mainly used, and the principles of projection geometry, descriptive geometry and ore body geometry are used to project the distribution of water-bearing or water-resisting strata on...

Problems solved by technology

[0006] However, the published technology still has the following flaws. First, the technology for discriminating sedimentary geological features by the public method is relatively simple, and the analysis is only based on the probability accumulation curve. The analysis results are not very accurate for the complex geological features. Second, the Markov principle of sedimentary microfacies modeling is a stochastic modeling method. The stochastic simulation method has great uncertainty, and only relying on mathematical calculations for sedimentary microfacies modeling cannot truly reflect the distribution of sedimentary microfacies

Third, the technical method used does not use structural modeling technology, which cannot reflect the control of structural features on coal-bearing or water-resisting layers
