Problems solved by technology

[0004] However, the currently disclosed stirrable intermediate container has the following problems: 1) the connection between the stirring motor and the piston affects the pressure resistance of the intermediate container, and the pressure resistance of the intermediate container is poor; 2) the heat resistance of the stirring motor is poor, so that the displacement fluid can only Partial heating in the intermediate container, and the heating effect is difficult to guarantee after the fluid flows out of the intermediate container, resulting in distortion of the fluid temperature

Embodiment 1

[0051] Such as Figure 6 As shown, before the experiment, in order to further determine the feasibility of the device, the stirring mechanism 6 was taken out separately, and the piston mechanism 4 was removed, and the magnetic rotor 603 was put into a transparent airtight container filled with water, and it was found that the container was filled with water. The magnetic rotor 603 can still rotate normally, therefore, the magnetic rotor 603 can also work normally when the intermediate container is filled with the experimental fluid and sealed, and the experimental stirring function can be achieved.

Embodiment 2

[0053] Such as Figure 7 As shown, in order to further confirm the feasibility of the device, the magnetic rotor 603 is placed in a stainless steel intermediate container with a wall thickness of 1 cm, placed on a magnetic stirrer, and the magnetic stirring can still be performed normally after the saturated water is pressurized to 10 MPa. Therefore, in the process of pressurized displacement, the pressure does not affect the work of the magnetic rotor 603, and the function of continuous mixing and stirring can be realized, and the process temperature is 100°C, and the experimental process is resistant to high temperature and high pressure. This embodiment is to verify the effect of magnetic stirring under pressure, and simulate the situation where the magnetic rotor 603 is stirred after being pressurized in the high-temperature and high-pressure stirrable intermediate container device 9 . Through this embodiment, it is verified that the experiment runs stably and the scheme i...

Abstract

The invention discloses a high-temperature and high-pressure-resistant stirrable intermediate container device and a porous medium displacement experimental system, comprising an intermediate container and a stirring mechanism, the intermediate container includes a cylinder body, an upper end cover, a lower end cover, an upper end cover, a lower end cover and a cylinder The body is screwed tightly and sealed, and the stirring mechanism is arranged in the intermediate container; the upper end cover and the lower end cover are provided with axial through holes, and the top of the upper end cover and the bottom of the lower end cover are connected with two open valves; the stirring The mechanism is a cylindrical structure, and its outer diameter matches the inner diameter of the cylinder. The side of the stirring mechanism moves up and down along the inner wall of the cylinder. The stirring mechanism is equipped with a piston mechanism to seal and isolate the upper and lower parts of the cylinder. The invention improves the structure of the existing intermediate container so that it can withstand high temperature and high pressure and realize the stirring function. It can also increase or decrease the number of battery packs to change the battery capacity to meet the needs of different stirring times. At the same time, the control system is improved to make it better. achieve stirring.

Description

technical field [0001] The invention belongs to the technical field of oil and gas reservoir development instruments, and in particular relates to a high-temperature and high-pressure-resistant stirrable intermediate container device and a porous medium displacement experimental system. Background technique [0002] In the process of oil extraction, porous media displacement experiments are often used to guide field production. For example, in the tertiary oil recovery process of oil and gas reservoirs, when the mechanism of enhanced oil recovery is studied through indoor porous media displacement experiments, the crude oil dilution, emulsification, polymer flooding, particle suspension liquid flooding (such as microsphere flooding), secondary flooding, etc. Experiments such as composite flooding involve a large number of chemical agents such as polymers, surfactants and co-surfactants. It includes a large number of production processes such as the dissolution of granular s...
