Abstract

The invention relates to a supercritical carbon dioxide flooding device. The supercritical carbon dioxide flooding device comprises an injection system, a vacuum system and a data collection and automatic control system, wherein a liquid collector is connected to the input end of the injection system through a pipeline, a model system is connected to the output end of the injection system througha pipeline, a vacuum system is connected to the output end of the injection system through a pipeline, and an extraction metering system is connected to the output end of the model system through a pipeline. According to the supercritical carbon dioxide flooding device, the modularization, the originality, the automatic control, the expandability and the like are used as principles, the idea is advanced, the operation is simple and convenient, the model can be freely combined, the data is tested accurately, the data is collected automatically, the overall design is attractive and elegant, thepracticability is high, various safety standards are met, and the device adopts the modular design and can be combined according to different test requirements; and multiple displacement tests such assimulation tests of supercritical carbon dioxide flooding, water flooding, gas flooding, chemical flooding and the like for improving the recovery efficiency can be carried out on a core under the condition that an oil reservoir is simulated.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development engineering, in particular to a supercritical carbon dioxide flooding device. Background technique [0002] The supercritical carbon dioxide flooding device is based on the displacement mechanism and the principle of similarity, and the oilfield site is designed in a similar proportion. Under the simulated reservoir pressure and temperature conditions, with the help of the latest achievements of modern science and technology, such as computer technology and advanced sensors Technology, automatic control technology, etc., conduct physical simulation experiments. Its main function is to carry out various displacement tests on cores under simulated reservoir conditions, such as supercritical carbon dioxide flooding, water flooding, gas flooding and chemical flooding, etc. to enhance recovery simulation tests. [0003] The existing carbon dioxide flooding devices are independent...
