Supercritical water crude oil dissolution observation device and dissolution degree detection method

Abstract

The invention discloses a supercritical water crude oil dissolution observation device and a dissolution degree detection method. Visible windows communicated with a reaction cavity are formed in thetwo sides of a reaction kettle body. A visual mirror is arranged in the visual window to realize visualization of the reaction cavity of the reaction kettle body. Meanwhile, the heating box body is used for heating the reaction kettle body. Light holes coaxial with the visible window in the reaction kettle body are formed in the box body walls on the two sides of the heating box body. The reactioncondition in the reaction kettle body can be acquired through the camera to obtain a supercritical reaction image. A dissolving process image of the crude oil during the period that the water is heated from the normal temperature to the supercritical state can be obtained. Observation of dissolution of the crude oil in the supercritical water is achieved, the in-situ observation of the dissolution condition of the crude oil in the supercritical water in the heating process is obtained by comparing the gray values of the pixel points in the reaction image with the minimum gray value of the dissolution of the crude oil in the supercritical water, the method is simple, and the detection result is accurate.

Description

technical field [0001] The invention belongs to the field of energy and environment, and in particular relates to a crude oil dissolution observation device in supercritical water and a dissolution degree detection method. Background technique [0002] Petroleum is an important strategic material for all countries in the world. Industrial development, national defense construction and people's basic necessities of life are inseparable from petroleum. The consumption of global oil and gas resources is increasing, but the remaining conventional oil and gas resources are decreasing, which makes the demand for efficient crude oil extraction and development of unconventional oil and gas resources more and more important. When water reaches the supercritical state of 374°C and 22.1MPa, it has high solubility, high diffusivity and high reactivity. Supercritical water can be applied to the process of petroleum refining and unconventional oil and gas resource development. The dissol...

Problems solved by technology

At present, the temperature and pressure of supercritical water are high, and there are strict requirements on the materials of supercritical water reactors. Generally, a supercritical water reactor structure with a fully sealed structure is used, which cannot realize the visualization of the internal reaction of the reactor, and cannot quickly and accurately determine the crude oil in the supercritical water reactor. critical solubility in water
