Embodiment 1

[0040] First, the invention discloses a piston type crude oil / water emulsification device, comprising:

[0041] A cylindrical shell 1, the cylindrical shell 1 has a cavity capable of holding liquid, and the shape of the cavity is cylindrical, the sulfur element in crude oil is divided into active sulfur and inactive sulfur, wherein the active sulfur It can directly interact with metals and cause corrosion of equipment. Sulfur-containing compounds in crude oil interact with other corrosive media such as oxides, chlorides, nitrides, naphthenic acids, and hydrogen to form a variety of sulfur-containing corrosive environments, so 711 anti-corrosion coatings can be used to treat cylindrical cylinders 1 for coating;

[0042] A piston assembly that fits into the barrel 1 and can reciprocate axially along the barrel 1;

[0043] A reciprocating mechanism hinged to the piston assembly;

[0044] In this example, please refer to figure 1 , the reciprocating mechanism is a four-bar lin...

Embodiment 2

[0058] The crude oil / water emulsification method of piston type uses the crude oil / water emulsification device of piston type as described in embodiment 1, comprises the following steps:

[0059] Step 1. Assembling the piston-type crude oil / water emulsification device; in this step, the sieve plates 6 with different apertures are mainly assembled;

[0060] Step 2, setting the temperature of the constant temperature oven 8, so that the emulsification is carried out under a certain temperature condition;

[0061] Step 3. Inject crude oil and water into the cylinder until it is full; it should be noted that, regarding how the crude oil and water are injected and in what ratio, in the prior art, the pipe connecting the crude oil source and the water source is usually A valve is set on the road, and a pump body is set in the pipeline; in other embodiments, crude oil or water can be contained in a container, and then indirectly drawn from the container;

[0062] Considering that if...

Abstract

The invention discloses a piston-type crude oil / water emulsifying device and an emulsifying method. The piston-type crude oil / water emulsifying device comprises a cylinder, a piston component and a reciprocating mechanism. The piston component cooperates with the cylinder and can move back and forth along the axial direction of the cylinder. The reciprocating mechanism is hinged to the piston component. The piston component comprises a rod and a sieve plate connected to the rod. A plurality of sieve holes are formed in the sieve plate along the axial direction of the rod. Two ends of the cylinder are sealed. A liquid inlet and a liquid outlet are formed in the cylinder. The piston-type crude oil / water emulsifying device and the emulsifying method have the advantages that the emulsifying device is beneficial to the preparation of crude oil / water emulsified solutions with high uniformity, the problem of low uniformity in the crude oil emulsion preparation process can be effectively solved, and reliable property representation of the crude oil / water emulsified solutions and kinetic studies on emulsions in relevant tests and projects are ensured.

Description

technical field [0001] The invention relates to the technical field of crude oil / water emulsification processing equipment, in particular to a piston type crude oil / water emulsification device and emulsification method. Background technique [0002] Emulsions are dispersions in which one liquid is dispersed in the form of droplets in another immiscible liquid. Crude oil will also form an emulsion during the extraction process. For example, the crude oil extracted from the crude oil reservoir will contain some water in the crude oil, mostly a crude oil-water mixture, which can easily form a crude oil-water emulsion after passing through the wellbore and the gathering and transportation pipeline. Chemical agents injected during the tertiary recovery of crude oil in crude oil fields can also emulsify crude oil to form emulsions. Due to the great difficulty in simulating the formation process of underground crude oil emulsion indoors, in order to study the surface properties an...
