Abstract

The invention belongs to the technical field of foam performance study chip analysis, and mainly relates to a glass medium model that imitates a rock core structure and can be used for foam flooding and percolation mechanism study in tertiary oil recovery. The glass medium model includes a first liquid inlet pool, a second liquid inlet pool, a glass substrate, coverglass, a drainage hole, a drainage pool, a drainage pool channel, a micro channel imitating the rock core structure, a first liquid inlet hole, a second liquid inlet hole, a microbubble generation module and a microbubble splitting module. Specifically, the micro channel imitating the rock core structure is etched on the glass substrate; the first liquid inlet hole, the second liquid inlet hole, and the drainage hole are respectively disposed at two ends of the coverglass; the two liquid inlet holes are communicated with the microbubble generation module respectively through the two liquid inlet pools; the microbubble generation module is communicated with the microbubble splitting module; the microbubble splitting module is communicated with the micro channel imitating the rock core structure; and two ends of the drainage pool channel are respectively communicated with the tail of the micro channel imitating the rock core structure and the drainage pool, and the drainage pool is communicated with the drainage hole.

Description

technical field [0001] The invention belongs to the technical field of foam performance research chip analysis, and mainly relates to a glass medium model imitating rock core structure that can be used for foam displacement and seepage mechanism research in tertiary oil recovery. Background technique [0002] At present, my country's demand for petroleum energy is increasing day by day, and the difficulty of petroleum exploration is increasing. How to further improve the recovery rate of crude oil has become an urgent problem for scientific research workers. There are mainly four types of physical models for enhanced oil recovery technology, foam flooding and seepage mechanism research: (1) Physical models for natural cores and artificial cores: they are currently commonly used for physical simulation of displacement. This model maintains the pore structure of the real formation rock well, but the displacement process of this model is invisible, and the relevant mechanism ca...
