A method and device for studying the percolation characteristics of rock mass pores and fissure structures and seats

Abstract

The invention relates to a method and device for researching the hole-and-fissure structure characteristic and the site percolation characteristic of rock. The device comprises a rock core experimental device, an operation table, an image magnification device, a transmitting-mirror scanning image processing system and a rock cutting system. The rock core experimental device comprises a tested piece composed of a standard rock core and a rock-core clamping device, the tested piece is placed on a sliding base, a scale ruler is arranged on the upper surface of the operation table, a support is arranged on one side of the operation table, a hydraulic jack is fixed to the side face of the support and jacks on the rock-core clamping device from the side face, and the standard rock core is clamped and fixed from one side through the rock-core clamping device; the rock cutting system is composed of a focused particle beam emitting head and an FIB intelligent control system, and the focused particle beam emitting head is fixed above the standard rock core. By means of the method and device, visual description of the distribution characteristics of hole-and-fissure dual media of the rock is achieved, and clear description is provided for the percolation characteristic and the communication characteristic of the rock.

Description

technical field [0001] The invention relates to the technical field of microcosmic rock mass in petroleum and natural gas, mining, geotechnical and other engineering, in particular to a method and device for studying rock mass pore and fissure structure and seat percolation characteristics. Background technique [0002] In the production of conventional and unconventional oil and gas reservoirs, the dual media of pores and fractures is a common type of media. Due to the complex structure and characteristics of different types of rock mass, as well as the inaccurate description of the internal pore and fracture structure characteristics of the rock mass, there are many technical and safety problems that cannot be solved in actual mining. At present, the research on the internal structural characteristics of rock mass is limited to porous media, mainly based on the study of the characteristics of the largest percolation cluster based on statistical probability, and the influen...
