Design method of borehole fracture visualization system

Abstract

The invention belongs to the technical field of borehole fracture visualization, and discloses a design method of a borehole fracture visualization system. The design method comprises the following steps that firstly, unified coordinate processing is conducted on a borehole basic diagram of a research area, basic information of a drill site is discretized to obtain a spatial data volume comprising spatial coordinate information and non-spatial information, and standardization processing is conducted on acquired actually measured data; the spatial coordinate information and the actually measured data in the spatial data volume are split according to space positions, and grid division is conducted; after fracture data are judged, data filling and assignment are conducted according to grid division, splicing is conducted, the actually measured data are corrected to obtain a final fracture model, visualization is achieved, specific information of fractures is calculated according to obtained result, and information such as the length, the width, the inclination angle and the proportion of the fractures is obtained. The design method is used for realizing visualization treatment of different fractures under different arrangement drill holes, and the problems that the fracture development degree is not clear and the distribution position is not detailed are solved.

Description

technical field [0001] The invention belongs to the technical field of borehole fissure visualization, and in particular relates to a design method of a borehole fissure visualization system. Background technique [0002] Gas drainage is the fundamental measure and main way to control and utilize coal mine gas. However, in most cases, the gas drainage rate is generally low. The main reason is that the stability of the hole wall is poor. Gas leakage, and the development of internal fissures in the sealing section often promotes gas extraction. [0003] As early as the early 1970s, the research on three-dimensional geological body modeling technology began to emerge abroad. In constructing a 3D model using multi-source data, scholars mine the characteristics of multi-source data. For example, some scholars use potential data fields, seismic images and surface data, and drilling data combined with planar geological data interpreted by geological experts. data and other data s...
