Description
DEVICE AND METHOD FOR TESTING FOAM PROPERTIES BASED ON 0"
[0001] 1. Technical Field
[0002] The present invention relates to the technical field of foam property evaluation, and more particularly, to a device and method for testing foam properties based on nanoparticle stabilization.
[0003] 2. Description of Related Art
[0004] Foam fluid is widely applied in the exploitation of petroleum, and foam systems of different gas sources have been extensively developed. For example, CO; foam systems have become a research hotspot because of their unique properties. However, the stability of foam systems has always restricted the application of similar foam systems. In recent years, the stabilization of foam systems with nanoparticles has become a crucial means to improve foam properties. The added nanoparticles can form a layer of solid-phase network structure on the surface of a liquid film to improve the overall stability of a foam system.
[0005] The dispersion effect, type and concentration of nanoparticles may affect the properties of nanoparticle-stabilized foam systems. The existing evaluation devices do not consider the dispersion effects of nano-systems. The well dispersed solution can obtain different foaming effects at different time and under different conditions. The evaluation means on foam properties mainly include stirring or bubbling bulk phase evaluation and formation seepage evaluation, and corresponding evaluation indexes include foaming volume, half-life and resistance factor. However, the microstructure and overall property of foam are greatly changed after the addition of nanoparcticles, and the conventional evaluation indexes cannot reflect such changes. Therefore, the effect of nanoparticles cannot be analyzed intuitively and effectively.
[0006] In order to better evaluate the foam system stabilized by nanoparticles, a property 1 evaluation device and a reasonable evaluation method are urgently needed. LU500887
[0007] The objective of the present invention is to provide a device and method for testing foam properties based on nanoparticle stabilization in order to solve the evaluation problems on the dynamic structural change of a foam system stabilized by nanoparticles.
[0008] The technical solution of the present invention is: a device for testing foam properties based on nanoparticle stabilization includes an ultrasonic dispersion instrument, a peristaltic pump, a first pipe, a second pipe, a third pipe, an organic glass container, a first high-definition (HD) camera, a second HD camera, a third HD camera, a gas cylinder, and a computer;
[0009] A first output port of the peristaltic pump is connected to the ultrasonic dispersion instrument by the first pipe; a second output port of the peristaltic pump is connected to the organic glass container by the second pipe; a gas outlet of the gas cylinder is connected to the bottom of the organic glass container by the third pipe; the first HD camera, the second HD camera and the third HD camera are evenly disposed on one side of the organic glass container; and the first HD camera, the second HD camera and the third HD camera are all connected to a computer by communication.
[0010] Further, the ultrasonic dispersion instrument is to hold a surfactant solution containing nanoparticles in a set proportion;
[0011] The peristaltic pump is used to pump and inject a foam solution obtained by dispersing the surfactant solution;
[0012] The organic glass container is used to observe the foaming status of foam entering the container;
[0013] The first HD camera, the second HD camera and the third HD camera are all used to capture foam structure images in real time and to display and store same in the computer.
[0014] Further, a first check valve is disposed on the first pipe; a second check valve-15>00887 disposed on the second pipe; a first needle valve is disposed at the end of the third pipe close to the organic glass container; a second needle valve is disposed at the other end of the third pipe close to the gas cylinder; a gas flow meter is disposed between the first needle valve and the second needle valve.
[0015] The first check valve is used to control the foam solution into the peristaltic pump without flowing back to the ultrasonic dispersion instrument; the second check valve is used to control the foam solution into the organic glass container without flowing back to the peristaltic pump.
[0016] Further, a first prism, a second prism and a third prism are evenly disposed on the organic glass container; the first prism, the second prism and the third prism are respectively at the same horizontal plane as the first HD camera, the second HD camera and the third HD camera,
[0017] The first prism, the second prism and the third prism are all used to convert a curved window of the organic glass container into a plane window. This function can facilitate image processing and fractal dimension calculation, because the two steps are based on a two-dimensional plane.
[0018] The beneficial effects of the present invention are: the property testing device of the present invention, which involves the connection control of components such as the ultrasonic dispersion instrument, the peristaltic pump and the check valves, is simple in structure and easy to implement, and provides an appropriate way for complex dispersion systems such as a nanoparticle-stabilized foam system.
[0019] Based on the above system, the present invention further proposes a method for testing foam properties based on nanoparticle stabilization, including the following steps:
[0020] S1: preparing a surfactant solution containing nanoparticles in a set proportion, and adding same to the ultrasonic dispersion instrument for dispersion within a preset time;
[0021] S2: pumping the foam solution obtained by the dispersion into a syringe with 412500887 peristaltic pump, and injecting the foam solution into the organic glass container through the syringe;
[0022] S3: opening the first needle valve and the second needle valve, controlling the gas in the gas cylinder to be injected into the organic glass container by the gas flow meter, and treating the foam solution with a bubbling method to produce foam;
[0023] S4: capturing foam structure images of different positions by the first HD camera, the second HD camera and the third HD camera respectively;
[0024] SS: binarizing the foam structure images of different positions, and performing fractal dimension calculation on the binary foam structure images by using a box counting method to obtain fractal dimensions of a foam structure, thus completing the foam property test.
[0025] Beneficial effects of the present invention:
[0026] (1) The present invention relates to a fractal evaluation method for the properties of a nanoparticle-stabilized foam system, mainly including image capture, image processing and fractal calculation. The structure of the foam structure is directly analyzed based on the fractal theory, and a bridge between a microstructure and macroscopic properties of nanoparticle foam is built, which improves the accuracy of evaluation results and makes up for the deficiencies of conventional evaluation methods.
[0027] (2) The evaluation method of the present invention realizes real-time and accurate measurement of the properties and dynamic structure of the foam system stabilized by nanoparticles.

[0037] In the embodiment of the present invention, the ultrasonic dispersion instrument 1 is used to hold surfactant solution containing nanoparticles in a set proportion; LU500887
[0038] The peristaltic pump 2 is used to pump and inject the foam solution which is obtained by dispersing the surfactant solution.
[0039] The organic glass container 4 is used to observe the foaming condition of the foam entering the container.
[0040] The first HD camera 5-1, the second HD camera 5-2 and the third HD camera 5-3 are all used to capture foam structure images in real time and to display and store them in the computer 7.
[0041] In the embodiment of the present invention as particularly shown in FIG. 1, the first check valve 8-1 is disposed on the first pipe 3-1; the second check valve 8-2 is disposed on the second pipe 3-2; the first needle valve 9-1 is disposed on one side of the third pipe 3-3 close to the organic glass container 4; while the second needle valve 9-2 is disposed on the other side of the third pipe 3-3 close to the gas cylinder 6; the gas flow meter 10 is disposed between the first needle valve 9-1 and the second needle valve 9-2;
[0042] The first check valve 8-1 is used to control the foam solution into the peristaltic pump 2 without flowing back to the ultrasonic dispersing instrument 1; the second check valve 8-2 is used to control the foam solution into the organic glass container 4 without flowing back to the peristaltic pump 2.
[0043] In the embodiment of the present invention as particularly shown in FIG. 1, the first prism 11-1, the second prism 11-2 and the third prism 11-3 are evenly disposed on the organic glass container 4; The first prism 11-1, the second prism 11-2 and the third prism 11-3 are at the same horizontal plane with the first HD camera 5-1, the second HD camera 5-2 and the third HD camera 5-3 respectively;

[0045] According to the above system, the present invention also proposes the foam property testing method based on nanoparticle stabilization, including the following steps: LU500887
[0046] S1: preparing the surfactant solution containing nanoparticles in a set proportion, adding it to the ultrasonic dispersion instrument and dispersing it within a preset time; the foam solution includes 0.25wt% APG (alkyl glycoside) + 1.5wt% SiO»; the dispersion time is 10 min; however, in the practical experiment, the dispersion time should be more than 10 min for the best effect, or there is still nanoparticle aggregation in the solution;
[0047] S2: pumping the foam solution obtained by dispersion into a syringe with the peristaltic pump, and injecting the foam solution through the syringe into the organic glass container;
[0048] S3: opening the first needle valve and the second needle valve to control the gas of the gas cylinder to inject into the organic glass container at the rate of 0.5 mL/min by a gas flow meter, and processing the foam solution with the bubbling method to produce foam;
[0049] S4: acquiring the foam structure images at different positions by the first HD camera, the second HD camera and the third HD camera respectively;
[0050] SS: converting the foam structure images at different positions to the binary images and adopting the box counting method to calculate and obtain the fractal dimension of the binary images, so as to complete the foam property test. The larger the fractal dimension, the more dispersed the foam structure and the worse the property, while the smaller the fractal dimension, the more uniform the foam and the better the property.
[0051] For example, in the specific operation, the acquired 30s image is processed and calculated its fractal dimension, as shown in FIG. 3. As can be seen in FIG. 3, the fractal dimension of the lower part of the organic glass cylinder 1s relatively small. Affected by the foam drainage, the more upward the part of organic glass cylinder, the worse the shape, and the fractal dimension becomes gradually larger.
[0052] Working principle and process of the present invention: add the foam solution to the ultrasonic dispersion instrument for dispersion; pump the foam solution obtained by dispersion into a syringe with the peristaltic pump, and inject the foam solution through the syringe into {100887 organic glass container; open the first needle valve and the second needle valve to control the gas of the gas cylinder to inject into the organic glass container at the rate of 0.5 mL/min by the gas flow meter, and process the foam solution with the bubbling method to produce foam; acquire the foam structure images at different positions by the first HD camera, the second HD camera and the third HD camera respectively; convert the foam structure images at different positions to the binary images and adopt the box counting method to calculate and obtain the fractal dimension of the binary images, so as to complete the foam property test. The larger the fractal dimension, the more dispersed the foam structure and the worse the property, while the smaller the fractal dimension, the more uniform the foam and the better the property.
[0053] The present invention enables the complete testing of nanoparticle foam stability without changing equipment. The fractal method used for the evaluation has better property in quantifying the foam structure compared to the traditional observed timing methods based on foaming volume and half-life.
[0054] The beneficial effect of the present invention:
