Description

Technical Field

[0001] This invention relates to the field of dispersion device technology, specifically to an acid-dispersing agent dispersion device. Background Technology

[0002] During acid fracturing in oil wells, it is necessary to promptly discharge the flowback fluid from the well to the surface. Normally, the flowback fluid is quickly discharged to the surface by relying on the formation pressure itself. However, when the formation pressure weakens, the flowback rate of the flowback fluid in the well decreases significantly. At this time, flowback aids are required. Flowback aids are a type of additive used in fracturing fluids. They can reduce the surface tension and interfacial tension of the fracturing fluid, increase the flowback volume, and reduce the damage of the fracturing fluid to the formation. During the use of flowback aids, a flowback aid dispersion device is required. Existing flowback aid dispersion devices are usually housed inside a mixing tank. Depending on the site conditions, different additives may be added to the mixing tank. When these additives are mixed with the flowback aid, they can help ensure the stable use of the flowback aid in the field.

[0003] Existing dispersion devices for discharge aids rely primarily on the stirring structure inside the mixing tank when mixing additives and discharge aids. This stirring structure typically consists of stirring blades and stirring rollers. While the combination of stirring blades and rollers does achieve proper mixing of additives and discharge aids within the mixing tank, some shortcomings remain in practical application, such as:

[0004] The inner wall of the mixing tank of the existing drainage aid dispersion device is not equipped with a good auxiliary stirring structure. When the stirring structure drives the drainage aid and additives inside the mixing tank to mix, the drainage aid and additives are prone to sticking to the inner wall of the mixing tank, resulting in poor mixing efficiency of the drainage aid and additives.

[0005] The storage structure of existing drainage aid dispersion devices is usually set on one side of the mixing tank. This causes the drainage aid and additives to flow into the interior of the mixing tank through one side, which makes it difficult for the drainage aid and additives to mix quickly inside the mixing tank, resulting in poor mixing efficiency of the drainage aid and additives.

[0006] Therefore, we propose an acid-discharging agent dispersion device. Summary of the Invention

[0007] One of the technical problems this application aims to solve is that the discharge aid and additives tend to adhere to the inner wall of the mixing tank and cannot facilitate rapid mixing of the discharge aid and additives inside the mixing tank.

[0008] To address the aforementioned technical problems, this application provides an acid discharge aid dispersion device, comprising a collection tank and a stirring structure rotatably connected inside the collection tank, and further comprising:

[0009] The upper and lower dispensing caps are symmetrically and fixedly connected to the storage container. Both the upper and lower dispensing caps are hollow structures. The upper and lower dispensing caps can seal the inner cavity of the storage container and enable the stirring structure to mix the dispensing aid inside the storage container.

[0010] A first diversion pipe and a second diversion pipe are fixedly connected. The first diversion pipe is fixedly connected to the upper liquid distribution cover, and the second diversion pipe is fixedly connected to the lower liquid distribution cover. A first liquid outlet blade and a second liquid outlet blade are fixedly connected to both the first diversion pipe and the second diversion pipe. The first liquid outlet blade and the second liquid outlet blade on the first diversion pipe are opposite to the first liquid outlet blade and the second liquid outlet blade on the second diversion pipe. The first liquid outlet blade and the second liquid outlet blade are provided with liquid outlet holes. When the stirring structure agitates the drainage aid, the first liquid outlet blade and the second liquid outlet blade can disturb the drainage aid inside the collection tank.

[0011] In some embodiments, the stirring structure is located at the center of the upper liquid distribution cover, the first diversion tube is evenly distributed on the outside of the stirring structure, and the second diversion tube is evenly distributed on the outside of the first diversion tube.

[0012] In some embodiments, a drive motor is detachably connected to the upper part of the upper liquid distribution cover, the output shaft of the drive motor is fixedly connected to the stirring structure, and an upper conveying pipe is fixedly connected to the upper liquid distribution cover on one side of the drive motor, the inner cavity of the upper conveying pipe communicating with the inner cavity of the upper liquid distribution cover.

[0013] In some embodiments, a discharge pipe is fixedly connected to the lower part of the lower liquid distribution cover, and a lower delivery pipe is fixedly connected to the lower part of the lower liquid distribution cover on one side of the discharge pipe, with the inner cavity of the lower delivery pipe communicating with the inner cavity of the lower liquid distribution cover.

[0014] In some embodiments, the first liquid outlet blade and the second liquid outlet blade are equally spaced on the first and second diversion pipes, the inner cavities of the first and second liquid outlet blades are connected to the inner cavities of the first and second diversion pipes, and the second liquid outlet blade is distributed at the lower part of the first liquid outlet blade.

[0015] In some embodiments, the included angle between the second liquid outlet blade and the liquid outlet hole is 45 degrees, and the cross-sections of the first liquid outlet blade and the second liquid outlet blade are both arc-shaped.

[0016] In some embodiments, a liquid supply pipe is fixedly connected to the upper part of one side of the storage bucket, and the number of liquid supply pipes is two.

[0017] This invention has at least the following beneficial effects:

[0018] The first and second diversion pipes in the device are distributed opposite to each other, and the first and second liquid outlet blades on the first diversion pipe are distributed opposite to the first and second liquid outlet blades on the second diversion pipe. This can realize the rapid mixing of the discharge aid discharged from the first and second diversion pipes, and can improve the mixing efficiency of the discharge aid in the device.

[0019] The first diversion pipe in the device is located on the outside of the stirring structure, and the second diversion pipe is located on the outside of the first diversion pipe. When the stirring structure drives the agitator inside the collection tank to agitate, the first and second liquid outlet blades on the first and second diversion pipes can turbulent the agitator, enabling the agitator to be quickly mixed inside the collection tank.

[0020] The device has an included angle between the first and second liquid outlet blades, and liquid outlet holes are provided on the first and second liquid outlet blades. This allows the first and second liquid outlet blades to spray the drainage aid into the inside of the collection tank at multiple angles through the liquid outlet holes, which is beneficial for the first and second liquid outlet blades to turbulent the drainage aid.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1-2 5. The present invention provides a technical solution:

[0029] An acid discharge aid dispersion device includes a collection tank 4 and a stirring structure 11 rotatably connected inside the collection tank 4, and further includes:

[0030] The upper liquid dispensing cap 3 and the lower liquid dispensing cap 10 are symmetrically and fixedly connected to the storage tank 4. Both the upper liquid dispensing cap 3 and the lower liquid dispensing cap 10 are hollow structures. The upper liquid dispensing cap 3 and the lower liquid dispensing cap 10 can seal the inner cavity of the storage tank 4, and can enable the stirring structure 11 to drive the mixing of the dispensing agent inside the storage tank 4.

[0031] When the upper liquid-dispensing cap 3 and the lower liquid-dispensing cap 10 seal the inner cavity of the storage tank 4, the stirring structure 11 can stir the drainage aid inside the storage tank 4, which can help the drainage aid mix inside the storage tank 4.

[0032] Example 2: Please refer to Figure 1-5 The present invention provides a technical solution:

[0033] The first diversion pipe 8 and the second diversion pipe 9 are fixedly connected. The first diversion pipe 8 is fixedly connected to the upper liquid distribution cover 3, and the second diversion pipe 9 is fixedly connected to the lower liquid distribution cover 10. The first liquid outlet blade 82 and the second liquid outlet blade 83 are fixedly connected to the first diversion pipe 8 and the second liquid outlet blade 83 on the first diversion pipe 8. The first liquid outlet blade 82 and the second liquid outlet blade 83 are opposite to the first liquid outlet blade 82 and the second liquid outlet blade 83 on the second diversion pipe 9. The first liquid outlet blade 82 and the second liquid outlet blade 83 are provided with liquid outlet holes 81. When the stirring structure 11 agitates the discharge aid, the first liquid outlet blade 82 and the second liquid outlet blade 83 can disturb the discharge aid inside the collection tank 4.

[0034] The stirring structure 11 is located at the center of the upper liquid distribution cover 3. The first diversion tube 8 is distributed at equal intervals on the outside of the stirring structure 11, and the second diversion tube 9 is distributed at equal intervals on the outside of the first diversion tube 8.

[0035] The upper part of the upper liquid distribution cover 3 is detachably connected to the drive motor 1. The output shaft of the drive motor 1 is fixedly connected to the stirring structure 11. The upper liquid distribution cover 3 is fixedly connected to the upper conveying pipe 2 on one side of the drive motor 1.

The inner cavity of the lower conveying pipe 6 is connected to the inner cavity of the lower liquid distribution cover 10.

[0037] When the output shaft of the drive motor 1 drives the stirring structure 11 to agitate, the output shaft of the drive motor 1 can drive the agitator inside the storage tank 4 to agitate through the stirring structure 11. At this time, the first liquid outlet blade 82 and the second liquid outlet blade 83 can turbulent the agitator inside the storage tank 4. Since the first liquid outlet blade 82 and the second liquid outlet blade 83 are provided with liquid outlet holes 81, the first liquid outlet blade 82 and the second liquid outlet blade 83 can transfer the agitator in the first diversion pipe 8 and the second diversion pipe 9 to the inside of the storage tank 4, so that the agitator can be quickly mixed inside the storage tank 4.

[0038] Example 3: Please refer to Figure 1-5 The present invention provides a technical solution:

[0039] The first liquid outlet blade 82 and the second liquid outlet blade 83 are equally spaced on the first diversion pipe 8 and the second diversion pipe 9. The inner cavities of the first liquid outlet blade 82 and the second liquid outlet blade 83 are connected to the inner cavities of the first diversion pipe 8 and the second diversion pipe 9. The second liquid outlet blade 83 is distributed at the lower part of the first liquid outlet blade 82.

[0040] The included angle between the second liquid outlet blade 83 and the liquid outlet hole 81 is 45 degrees, and the cross-sections of the first liquid outlet blade 82 and the second liquid outlet blade 83 are both arc-shaped.

[0041] Two liquid supply pipes 5 are fixedly connected to the upper part of one side of the storage bucket 4.

[0042] There is an included angle between the first liquid outlet blade 82 and the second liquid outlet blade 83. At the same time, the first liquid outlet blade 82 and the second liquid outlet blade 83 are provided with liquid outlet holes 81, which can realize the first liquid outlet blade 82 and the second liquid outlet blade 83 spraying the drainage aid into the inside of the collection tank 4 at multiple angles through the liquid outlet holes 81. This can help the first liquid outlet blade 82 and the second liquid outlet blade 83 to turbulent the drainage aid.
