Description

Technical Field

[0001] The present invention relates to the technical field of oil extraction, and particularly to a wellhead microbubble continuous generation device. Background Technique

[0002] With the development of unconventional oil and gas resources, secondary and tertiary oil recovery technologies for improving the recovery rate of unconventional reservoirs have attracted extensive attention from scholars. Due to the unique property of foam that it can block water but not oil, good application effects have been achieved in the development of reservoirs in the medium and high water cut periods. The stability of foam is the key factor affecting the effect of improving the recovery rate. It is necessary to use a foam continuous generation device to generate foam to improve the oil recovery effect.

[0003] Existing foam continuous generation devices still have problems such as relatively large foam diameter, difficulty in removing adhered polymers in the reservoir, and high technical costs, which limit their popularization and use in low-permeability reservoirs. Compared with ordinary foam, microfoam has the characteristics of small diameter, large specific surface area, high stability, and fluidity similar to water. Microfoam flooding has advantages such as low injection pressure and wider swept volume. The injection pressure is only 1 / 3 of that of polymer flooding. At the same time, it can effectively control the gas mobility, expand the swept volume, and thus improve the recovery rate. It is a potential tertiary oil recovery technology. However, the foam continuous generation device generates ordinary foam and cannot improve the oil recovery rate. Summary of the Invention

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0027] Please refer to Figure 1-6 , a wellhead microbubble continuous generation device, including an installation base plate 1, a microbubble generation mechanism 2 is arranged above the installation base plate 1, and an air injection mechanism 3 is arranged on the front surface of the microbubble generation mechanism 2;

[0028] The microbubble generation mechanism 2 includes a mounting and fixing frame 201. The bottom surface of the mounting and fixing frame 201 is fixedly connected to the upper surface of the mounting base plate 1. The inner wall of the mounting and fixing frame 201 is fixedly connected with a surfactant storage tank 202. A rotating motor 203 is arranged on the front surface of the surfactant storage tank 202. The output end of the rotating motor 203 is fixedly connected with a rotating shaft 204. The rotating shaft 204 is rotatably connected inside the surfactant storage tank 202. Equally spaced connecting rotating rods 205 are fixedly connected to the outer surface of the rotating shaft 204. One end of each connecting rotating rod 205 away from the rotating shaft 204 is fixedly connected with a rotating ring 206. Each rotating ring 206 is slidably connected inside the surfactant storage tank 202. Equally spaced extension bars 207 are fixedly connected to the inner wall of each rotating ring 206. By setting the rotating motor 203, the power of the rotating motor 203 can be controlled to drive the rotating shaft 204 to rotate inside the surfactant storage tank 202. Since the surfactant storage tank 202 stores surfactant, the rotating rotating rings 206 and extension bars 207 can be used to pick up more surfactant. Thus, by blowing air with a relatively fast flow rate on the rotating rings 206, the principle of blowing bubbles can be conveniently used to generate stable and continuous microbubbles, which can play a role in improving the oil recovery rate;

[0029] An additive pipe 18 is fixedly connected and communicated with the front surface of the surfactant storage tank 202. One end of the additive pipe 18 away from the surfactant storage tank 202 is fixedly connected and communicated with a check valve 19. A check valve 19 is a valve whose closing member is a circular valve disc and blocks the reverse flow of the medium by its own weight and the pressure of the medium. The model of the check valve 19 is DH77X. The check valve 19 can be used to control the switch of the additive pipe 18, facilitating the delivery of surfactant into the surfactant storage tank 202, and preventing the surfactant from flowing directly out of the additive pipe 18, thus facilitating the use of the surfactant storage tank 202;

[0030] Stable bearings 7 are fixedly connected to both the front surface and the back surface of the surfactant storage tank 202. The inner ring of each stable bearing 7 is fixedly connected to the outer surface of the rotating shaft 204. By using the stable bearings 7 fixed on both sides of the surfactant storage tank 202, the rotating shaft 204 can rotate stably inside the surfactant storage tank 202, thereby improving the stability of the wellhead microbubble continuous generation device;

[0031] A retaining disc 8 is arranged on the back surface of one of the stable bearings 7. The front surface of the retaining disc 8 is fixedly connected to the end of the rotating shaft 204 away from the surfactant storage tank 202. Fixing the retaining disc 8 at one end of the rotating shaft 204 can use the retaining disc 8 to make the rotating shaft 204 rotate stably inside the surfactant storage tank 202, thereby further improving the stability of the microbubble continuous generation device.

[0032] The specific implementation manner of this embodiment is as follows: First, connect the rotating motor 203 to the power supply. When it is necessary to use this microbubble continuous generation device to transport a large amount of continuous and stable bubbles to the oil wellhead, first manually control the check valve 19, which can conveniently transport the surfactant into the surfactant storage tank 202 and prevent the surfactant from leaking out through the additive pipe 18, thus facilitating the use of the surfactant in the surfactant storage tank 202. By controlling the power supply of the rotating motor 203 and using the relatively fast-flowing air transported from one side of the microbubble continuous generation device, drive the connecting rotating rod 205 to rotate through the rotating motor 203, so that multiple rotating rings 206 can rotate in the surfactant storage tank 202. Each time a rotating ring 206 rotates one circle, it can pick up the surfactant once in the surfactant storage tank 202. Then, use the relatively fast-flowing air to blow towards the rotating ring 206, and utilize the principle of blowing bubbles to generate a large amount of continuous and stable bubbles, which can play a role in improving the oil recovery rate by using these microbubbles.

[0033] Please refer to Figure 1-6 , the gas injection mechanism 3 includes two groups of support legs 301. The bottom end of each group of support legs 301 is fixedly connected to the upper surface of the installation base plate 1. The top ends of the two groups of support legs 301 are jointly fixedly connected with an air pump 302. The air pump 302 is a device for exhausting air from or adding air to a closed space. The model of the air pump 302 is DL8060. The air pump 302 is electrically connected to the rotating motor 203 through a wire. The input end and the output end of the air pump 302 are respectively fixedly connected and communicated with an air delivery conduit 303 and an exhaust conduit 304. The end of the exhaust conduit 304 far away from the air pump 302 penetrates through the surfactant storage tank 202 and extends to the inside of the surfactant storage tank 202. One of the rotating rings 206 is communicated with the exhaust conduit 304. The front of the surfactant storage tank 202 is fixedly connected and communicated with a microbubble output pipe 305. The microbubble output pipe 305 is communicated with the exhaust conduit 304. Through the support legs 301, the air pump 302 can be fixed on one side of the surfactant storage tank 202. By controlling the power supply of the air pump 302 and using the air delivery conduit 303 to draw external air into the air pump 302, the air pump 302 is used to output high-flow air through the exhaust conduit 304. Since the exhaust conduit 304 is communicated with the surfactant storage tank 202, it is convenient to use the high-flow air generated by the air pump 302 to blow bubbles on the communicated rotating ring 206, which can play a role in facilitating the use of this wellhead microbubble continuous generation device;

[0034] The upper surface of the mounting base plate 1 is provided with two groups of mounting threaded holes 11. Each group of mounting threaded holes 11 is internally threadedly connected with a mounting bolt 4. The bottom end of each group of mounting bolts 4 penetrates through the mounting threaded holes 11 and extends below the mounting base plate 1. By manually placing the mounting base plate 1 at the position and drilling corresponding threaded holes for the mounting threaded holes 11, it is convenient to use the mounting bolts 4 to fix the mounting base plate 1 at the required position;

[0035] The outer surface of each group of mounting bolts 4 is fixedly connected with a fixing ring 15. The bottom surface of each group of fixing rings 15 is fixedly connected with a buffer spring 16. The inner wall of each group of buffer springs 16 is in contact with the outer surface of the mounting bolt 4. By using the fixing ring 15, the buffer spring 16 is fixed on the outer surface of the mounting bolt 4, so that the buffer spring 16 can buffer the impact force received by the mounting bolt 4;

[0036] The bottom end of each group of buffer springs 16 is fixedly connected with a buffer ring 17. The inner wall of each group of buffer rings 17 is in contact with the outer surface of the mounting bolt 4. The bottom surface of each group of buffer rings 17 is in contact with the upper surface of the mounting base plate 1. By using the buffer ring 17, the force-bearing area of the buffer spring 16 applied to the mounting base plate 1 is increased, so that the service life of the buffer spring 16 can be extended, and further the service life of the fixing structure can be extended;

[0037] The outer surface of the rotating motor 203 is fixedly connected with a fixing seat 9. The upper surface of the fixing seat 9 is fixedly connected with the outer surface of the exhaust duct 304. By using the fixing seat 9, the rotating motor 203 can be fixed on the outer surface of the exhaust duct 304, so that the rotating motor 203 can stably output power;

[0038] One end of the air delivery duct 303 far from the air pump 302 is fixedly communicated with a sliding box 5. The upper surface of the sliding box 5 is provided with a sliding groove 10. The sliding groove 10 is communicated with the air delivery duct 303. A sliding plate 13 is slidably connected inside the sliding box 5. A filter screen 14 is fixedly inlaid on the front surface of the sliding plate 13. By fixing one end of the air delivery duct 303 to the sliding box 5, it is convenient for the sliding plate 13 to slide in the sliding groove 10 opened on the sliding box 5, so as to conveniently filter the air passing through the air delivery duct 303 by using the filter screen 14;

[0039] The upper surface of the sliding plate 13 is fixedly connected with a pulling plate 6. The bottom surface of the pulling plate 6 is in contact with the upper surface of the sliding box 5. The upper surface of the pulling plate 6 is fixedly connected with a pulling handle 12. By manually pulling the pulling handle 12, it is convenient to use the pulling plate 6 to pull the sliding plate 13, so as to conveniently replace the filter screen 14.

[0040] The specific implementation of this embodiment is as follows: First, connect the air pump 302 to the power supply. When it is necessary to utilize the high-velocity air generated by the air injection mechanism 3 to generate microbubbles using the principle of blowing bubbles, first manually pull the handle 12, which can conveniently use the pulling plate 6 to pull the sliding plate 13, thereby facilitating the use of the filter screen 14 fixed inside the sliding plate 13 to filter the air passing through the air delivery conduit 303. Thus, by controlling the power supply of the air pump 302, the filtered air can be transported to its interior through the air delivery conduit 303. With the action of the air pump 302, the high-velocity air can be output through the exhaust conduit 304. Thereby, it can be connected to the surfactant storage tank 202 through the exhaust conduit 304, and the high-velocity air can be transported to one side of the rotating ring 206 rotating inside the surfactant storage tank 202 to blow the surfactant inside the rotating ring 206 to form a large number of stable bubbles, playing the role of conveniently and automatically outputting microbubbles to the oil wellhead.

[0041] Please refer to Figure 1-6, the specific implementation of this embodiment is as follows: First, connect the rotation motor 203 to the power supply. When it is necessary to use this microbubble continuous generation device to transport a large amount of continuous and stable bubbles to the oil wellhead, first manually control the check valve 19, which can facilitate the transportation of the surfactant into the surfactant storage tank 202 and prevent the surfactant from leaking out through the additive pipe 18, thus facilitating the use of the surfactant in the surfactant storage tank 202. By controlling the power supply of the rotation motor 203 and using the relatively fast-flowing air transported from one side of the microbubble continuous generation device, the rotation rod 205 is driven to rotate by the rotation motor 203, so that multiple rotating rings 206 can rotate in the surfactant storage tank 202. And every time a rotating ring 206 rotates one circle, it can pick up the surfactant once in the surfactant storage tank 202. Then, the relatively fast-flowing air is blown onto the rotating ring 206, and thus, by using the principle of blowing bubbles, a large number of continuous and stable bubbles can be generated, which can play the role of using this microbubble to improve the oil recovery rate. First, connect the air pump 302 to the power supply. When it is necessary to use the relatively fast-flowing air generated by this gas injection mechanism 3 to generate microbubbles by using the principle of blowing bubbles, first manually pull the pulling handle 12, which can facilitate the use of the pulling plate 6 to pull the sliding plate 13, and thus facilitate the use of the filter screen 14 fixed in the sliding plate 13 to filter the air passing through the air delivery conduit 303. Then, by controlling the power supply of the air pump 302, the filtered air can be transported into it through the air delivery conduit 303. And due to the function of the air pump 302, the relatively fast-flowing air can be output through the exhaust conduit 304. Thus, by connecting the exhaust conduit 304 to the surfactant storage tank 202, the relatively fast-flowing air can be transported to one side of the rotating ring 206 rotating in the surfactant storage tank 202 to blow the surfactant in the rotating ring 206 to form a large number of stable bubbles, which can play the role of facilitating the automatic output of microbubbles to the oil wellhead.
