Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction, and in particular to an extra-heavy oil steam mixer. Background Technology

[0002] Extra-heavy oil is a type of crude oil with extremely high viscosity and poor fluidity. Currently, steam injection and steam drive are the mainstream methods for extracting extra-heavy oil. By injecting high-temperature and high-pressure steam into the oil reservoir, the viscosity of the crude oil is reduced and its fluidity is improved. During the extraction process, the uniform mixing of steam and extra-heavy oil is the key to improving extraction efficiency and directly affects the crude oil recovery rate. Thus, extra-heavy oil steam mixers have emerged.

[0003] When the extra-heavy oil and steam enter the mixer, the porous structure disperses the steam into fine streams, while the steam distribution structure guides the steam into the extra-heavy oil stream at a uniform angle and speed, greatly increasing the contact area between the two and accelerating the transfer of heat from the steam to the high-viscosity extra-heavy oil, rapidly reducing its viscosity. At the same time, the stirring structure continues to operate, forcibly pushing the two fluids to mix violently through mechanical force, breaking down the viscosity barrier of the extra-heavy oil. During this process, the temperature and pressure monitoring device adjusts the operating parameters in real time to ensure that the two are always mixed efficiently and stably under optimal conditions.

[0004] Currently, extra-heavy oil steam mixers have significantly improved the efficiency of the crude oil extraction industry due to their high-efficiency mixing capabilities. However, because the extra-heavy oil entering the mixer has extremely high viscosity and poor flowability, some crude oil will adhere to the inner wall of the mixer due to viscosity during the mixing process. Over time, these deposits accumulate, which not only affects the normal operation of the equipment but also hinders the uniform mixing of extra-heavy oil and steam, thus reducing the efficiency of crude oil extraction. This has become a major problem restricting the efficient extraction of extra-heavy oil. To address this issue, an extra-heavy oil steam mixer is proposed. Utility Model Content

Multiple connecting columns are fixed on the outer wall, and each connecting column is slidably connected to a limiting column on the side away from the rotating column.

[0012] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0020] Furthermore, the two sides of the spring are in contact with one side of the connecting column and the inner wall of the flow cut-off plate, respectively.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, when the second motor is turned on, the power is transmitted to the rotating disk, which drives multiple protrusions to start rotating. The path formed by the rotation of these protrusions just passes through multiple sliders. When the sliders come into contact with the protrusions, the protruding structure of the protrusions causes the sliders to generate a height difference. This height difference causes the support column to move up and down reciprocally, thereby generating a vibration effect. This vibration is transmitted to the shell, which improves the mixing state of the extra-heavy oil and steam in the shell, prevents crude oil from adhering to the inner wall, and greatly improves the utilization rate of crude oil in the shell.

[0032] 2. In this utility model, when motor one is turned on, its driving end drives the rotating column to rotate. The rotating column then drives multiple connecting columns to rotate in a circle. The flow interrupter on the connecting column then moves in a circle around the rotating column. Due to the setting of the limiting column and the spring, the distance between the flow interrupter and the rotating column will change with the rotation speed of the rotating column driven by motor one. Since the multiple flow interrupters are in different positions, the original flow path is disrupted after the gas enters the shell. This greatly increases the contact area between crude oil and steam gas, allowing the two to mix more fully, thereby significantly improving the production efficiency of crude oil.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1 to 3This utility model provides an embodiment of an ultra-heavy oil vapor mixer, comprising a shell 1, which serves as an important mixing site. A support platform 9 is fixedly connected to the bottom of the shell 1, and a support column 10 is fixedly connected to the bottom of the support platform 9, making them tightly connected to the shell 1. A base 11 is slidably connected to the outer wall of the support column 10, which plays an important supporting role. A second motor 12 is fixedly connected inside the base 11, serving as an important power source. A rotating disk 13 is fixedly connected to the drive end of the second motor 12, allowing the driving force of the second motor 12 to be transmitted. Multiple protrusions 14 are fixedly connected to the top of the rotating disk 13, creating a height difference between the top of the rotating disk 13 and the top of the support column 10. Multiple sliders 15 are fixedly connected to the bottom of the support column 10. Fixed disks 2 are fixedly connected to both sides of the shell 1, making the entire device more stable. A first motor 3 is fixedly connected to one side of one of the fixed disks 2, serving as an important power source. A flow interruption component is fixedly connected to the drive end of the first motor 3.

[0041] Reference Figures 2 to 4 The flow-stopping assembly includes a rotating column 4, one side of which is fixedly connected to the drive end of motor 3, allowing the driving force of motor 3 to be transmitted. Multiple connecting columns 5 are fixedly connected to the outer wall of the rotating column 4. Limiting columns 6 are slidably connected to the side of each connecting column 5 away from the rotating column 4, allowing the outer wall of the limiting column 6 to slide inside the connecting column 5. A flow-stopping plate 8 is fixedly connected to the other side of the limiting column 6, serving to block the original flow path of the gas. The bottoms of multiple sliders 15 are slidably connected to the top of the rotating disk 13, creating a height difference when the sliders 15 contact the protrusion 14. The base 11 has an H-shaped cross-section, making the entire device more stable. Springs 7 are fitted onto the outer walls of the multiple limiting columns 6. The inner wall of the flow-stopping plate 8 is slidably connected to the connecting column 6. The outer wall of column 5 allows the flow-breaking plate 8 to slide and change distance on the outer wall of connecting column 5. One side of spring 7 is in contact with one side of connecting column 5, and the other side of spring 7 is in contact with the inner wall of flow-breaking plate 8, so that spring 7 can be squeezed and deformed to generate elastic force. The outer side of rotating column 4 is rotatably connected to the inner wall of fixed plate 2. Multiple air inlets and outlets 18 are fixedly connected to the outer wall of housing 1, so that steam gas can enter and exit housing 1. An oil inlet valve 16 is fixedly connected to the outer wall of housing 1, so that crude oil can enter housing 1. Two oil outlet valves 17 are fixedly connected to the outer wall of housing 1, so that crude oil can leave housing 1 after being fully mixed. The cross-sectional shape of support platform 9 is U-shaped. The bottom of rotating plate 13 is rotatably connected to the inside of base 11, making the whole device more stable.

[0042] Working principle: Open the oil inlet valve 16 to input crude oil into the housing 1. Inlet and outlet gas 18 are also input into the housing 1. Start motor 3 to drive the rotating column 4 to rotate multiple connecting columns 5 in a circular motion. This causes the flow interrupter 8 to move in a circular motion around the rotating column 4. Due to the presence of the limiting column 6 and the spring 7, the distance between the flow interrupter 8 and the rotating column 4 varies depending on the rotational speed driven by motor 3. The different positions of the multiple flow interrupters 8 disrupt the original flow path of the gas entering the housing 1, greatly increasing the contact area between the crude oil and the steam gas and allowing for more thorough mixing. This significantly improves the crude oil production efficiency. Start motor 12 to drive the rotating disk 13 to rotate multiple protrusions 14. The rotation path of the multiple protrusions 14 passes through multiple sliders 15, creating a height difference when the sliders 15 contact the protrusions 14. This causes the support column 10 to reciprocate up and down, achieving a vibration effect and thus causing the housing 1 to vibrate.
