Abstract

A device for mixing liquid phases, comprising a housing, two inlet pipelines, an outlet pipeline, characterized in that a flat cylinder made of porous ceramic with a seal is installed in the recess of the lower wall of the housing of the device, and the internal cavity of the housing is filled with uniform sand.

Description

The device relates to the field of mixing liquids, and can be used, in particular, in petrophysical studies of rock samples. In installations for the study of two-phase filtration to determine water saturation, core resistance is measured. Due to the insufficient miscibility of the phases supplied to the core input (water and oil), there is a significant variation in the readings of the measured resistance. The supply of pre-mixed phases at the entrance to the core holder increases the accuracy of the measured resistance.

There are many devices designed for mixing liquids (RU No. 209325, publ. 10/20/1997; RU No. 2080164, publ. 05/27/1997, etc.), but they all have a design complexity.

The objective of the proposed technical solution is to simplify the design of the device for mixing liquid phases while achieving the necessary homogeneity of the resulting mixture. Mixing the liquid phases is necessary to obtain a homogeneous emulsion having a characteristic that is stable in electrical resistance.

The solution to this problem is achieved by the fact that, according to known devices for mixing liquid phases, including a housing, two inlet pipelines, an outlet pipeline, a flat cylinder made of porous ceramic with a seal is installed in the recess of the lower wall of the housing of the proposed device, and the internal cavity of the housing is filled with uniform sand.

The drawing shows a diagram of the proposed device.

The device includes a casing 1 filled with homogeneous sand 2. Two pipelines 3 are connected to the casing in its upper part, intended for supplying two phases used for filtering through a core sample. In the lower part of the casing is connected to the discharge pipe 4. In the recess of the lower part of the casing using a seal 5, a flat cylinder 6 made of porous ceramic is installed.

The device operates as follows.

Through the inlet piping 3 in the cavity of the housing 1 of the device receives the liquid phase (water and oil) for mixing. The phases passing through sand 2, acting as a diffuser (flow divider), are divided into many small flows and mechanically mixed together. Different viscosity and density of media (oil and water) will lead to the fact that when passing through a porous medium (sand, ceramic), particles of one phase will be ahead of particles of another, which will also serve as an additional factor in mixing the phases supplied to the device.

When passing through the channels of the ceramic cylinder 6, an additional mixing of the phases occurs. Thus, the ceramic cylinder 6 performs two functions: additional (additional) phase mixing and eliminating sand from entering the outlet pipe.

The overall dimensions of the device casing and ceramic disk are determined in the process of research and development work.

The use of the proposed device in installations for the study of phase permeabilities will increase the accuracy of measuring the resistance used in determining the water saturation of the core sample. The design of the device is simple, while ensuring the necessary degree of mixing of the liquid phases required during the study of phase permeability.
