Abstract

A method and device for analyzing the percolation and connection characteristics of rock mass pores belong to the technical field of rock mass pore structure in engineering such as petroleum and natural gas, mining industry, and geotechnical engineering. The experimental core is selected on site, the core is polished, and the standard rock sample size is made according to the instrument regulations, and placed in the core experiment device; the standard core is scanned by the image magnification device and the transmission mirror scanning image processing system, and the scanned core image is scanned. It is transmitted to the computer image processing system, and the system processing software is installed in the computer processing system; the experimental core is longitudinally cut and scanned through the rock mass cutting system, and the single cut rock mass is transmitted to the computer image processing system in the form of a standard image; the computer The processing system performs grid division on a single core image and coordinates labeling. The present invention realizes the visual description of rock mass porosity, and gives a clear description of the internal structure of rock mass percolation and connection characteristics; more intuitive measurement The porosity of the rock mass.

Description

technical field [0001] The invention relates to a method and a device for analyzing the percolation and connection characteristics of rock mass pores, and belongs to the technical field of rock mass pore structure in engineering such as petroleum and natural gas, mining, rock and soil. Background technique [0002] In the technical fields of conventional and unconventional gas reservoir exploitation such as oilfield natural gas, shale gas and coalbed methane, due to the complex characteristics of the exploited rock mass, the description of the pore structure characteristics in the rock mass is not accurate enough, so that there are still problems in the mining process. Many technical and security issues cannot be resolved. At present, the research on the characteristics of the pore structure in the rock is mainly based on the study of the characteristics of the largest percolation group based on statistical probability. The complex connectivity of the internal pore structure...
