Two-dimensional high-temperature high-pressure macroscopic visual displacement experiment device and use method thereof

Abstract

The embodiment of the invention mainly aims to provide a two-dimensional macroscopic visual displacement experimental device and a use method thereof, so as to realize an experimental means for observing a displacement mechanism of a heavy oil reservoir through a flat tempered glass macroscopic model. In order to achieve the purpose, the two-dimensional high-temperature and high-pressure macroscopic visual displacement simulation experiment system for the thickened oil comprises a multi-element thermal fluid injection device, a macroscopic simulation experiment device, a visual data acquisition device and a metering device. The characteristics of the heavy oil reservoir are fully considered, convenience is provided for researching a heavy oil displacement mechanism through a macroscopic experiment, oil displacement mechanism research of an oil reservoir environment with top water, edge water and bottom water can be simulated, heavy oil reservoir displacement effect research under different well pattern arrangements can be carried out, and the method has the advantages of being low in experiment cost, high in working efficiency and the like and is suitable for popularization and application. And the requirements of heavy oil reservoir development and research can be met.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a two-dimensional high temperature and high pressure macroscopic visual displacement experimental device and a method for using the same. Background technique [0002] Understanding and mastering the mechanism of oil and gas development is very important for writing efficient development plans for oilfields. Many scholars at home and abroad have conducted research on the mechanism of various oil recovery methods in reservoirs, but most of them are aimed at thin oil and thick oil. There is very little research on oil. The main reason is that the displacement mechanism of heavy oil reservoirs cannot be truly understood due to the relatively high viscosity of heavy oil. Macroscopic visualization experiment is one of the effective means to study the mechanism of oil and gas seepage. Using high-temperature and high-strength tempered glass plates can conduct intu...
