Abstract

The invention provides a microfluidic technology-based fluid flow simulation experiment device and method. Micro-nano channel models with different characteristics are designed aiming at pore throat characteristics and pore throat scale characteristics of real oil reservoir rock. A migration process and the distribution state of fluid flowing in the micro-nano channel model are observed, recordedand quantitatively analyzed in real time; flow characteristic research when different fluids pass through the micro-nano channel model is realized, so that the micro-nano channel fluid flow simulationexperiment device based on the micro-fluidic technology has the effects of high simulation of real rock pore throat characteristics, accurate measurement data, flexible and repeatable operation and microcosmic visualization.

Description

technical field [0001] The invention relates to the technical field of microscopic fluid flow simulation, in particular to a fluid flow simulation experimental device based on microfluidic technology and a method thereof. Background technique [0002] In recent years, in the field of oil and gas field development, with the continuous innovation of oil and gas extraction technology, although the degree of exploitation has continued to increase, a large amount of remaining oil is still stored in the ground, which is difficult to recover. The remaining oil occupies a larger proportion. In tight rock reservoirs, because the crude oil is affected by the capillary force and surface tension of the micropores and fractures of the rock in the reservoir, it is difficult to be driven out by conventional production methods. As a common oil recovery method, yield has been widely used in the development of tight rock reservoirs in recent years. Common injection fluids include chemical re...
