[0002] An oil field is a geographical area where oil and natural gas accumulate in underground rock layers to form commercially exploitable reserves. The formation of an oil field is a long and complex process involving changes in the earth's crust, the deposition of biological organic matter and subsequent geological changes. In order to maintain high and stable production of oil fields and improve the ultimate recovery rate of oil fields, many oil fields at home and abroad use the method of injecting water into oil layers to maintain formation pressure and improve oil well recovery. The injector is a special downhole tool used for quantitative water injection into each oil layer during stratified water injection. The injection well allocates the injection volume according to the properties of the oil layers in different layers.

[0003] When the existing water distributor is injecting water into the middle layer of the oil well, the impurities accumulated inside the oil well will enter the water distributor through the water injection holes on the water distributor, causing the water distributor to be blocked, affecting the water injection effect of the water distributor, and it is difficult to clean the impurities precipitated inside the water distributor, thereby reducing the service life of the water distributor.

DETAILED DESCRIPTION

[0037] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0038] like Figure 1-Figure 9As shown, the variable frequency speed regulating water injection distributor for oil wells provided in this embodiment comprises a distributor body 1 and a sealing ring 2 rotatably arranged in the middle of the distributor body 1. A water injection port 104 is provided at the upper end of the distributor body 1. A variable frequency speed regulating water pump is connected to the water injection port 104. Through the output frequency of the variable frequency speed regulating water pump, this control method can adjust the speed of the water injection pump in real time according to the actual water injection demand of the oil field, thereby realizing accurate control of the water injection amount. A lower layer drain port 105 is provided at the lower end of the distributor body 1. A middle layer water injection channel 106 is provided inside the water injection port 104. 08, a middle-layer drain port 109 connected to the middle-layer water injection channel 108 is provided inside the middle-layer water injection channel 108, and a middle-layer drain port 109 is provided in the middle of the water distributor body 1 through the middle-layer water injection channel 108, and water can be discharged to the middle position of the water distributor body 1 through the middle-layer drain port 109. Before the water is discharged through the middle-layer drain port 109, a sealing ring drain hole 201 corresponding to the middle-layer drain port 109 is provided on the sealing ring 2, which needs to correspond to the sealing ring drain hole 201 on the sealing ring 2, and the middle-layer drain port 109 and the sealing ring 2 are connected. After the drainage hole 201 corresponds, water can be discharged from the middle drainage port 109. A sealing ring driving device 4 is fixedly arranged inside the water injection port 104. The sealing ring driving device 4 includes a sealing driving mechanism 9, a transmission mechanism 7 and a magnet driving mechanism 8. The sealing driving mechanism 9 drives the magnet driving mechanism 8 to slide through the transmission mechanism 7. The outer side surface of the magnet driving mechanism 8 is fixedly provided with a first rubidium magnet 803. The inner side surface of the sealing ring 2 is fixedly provided with a second rubidium magnet 10 corresponding to the first rubidium magnet 803. The sealing ring driving device 4 is used to drive the sealing ring 2 The sealing ring 2 rotates, so if it is necessary to drain water from the middle drain port 109, it is necessary to rotate the sealing ring 2 so that the middle drain port 109 corresponds to the sealing ring drain hole 201. A first rubidium magnet 803 is fixedly arranged on one side of the magnet driving mechanism 8, and a second rubidium magnet 10 corresponding to the first rubidium magnet 803 is fixedly arranged on the sealing ring 2. Therefore, as long as the first rubidium magnet 803 is rotated, the sealing ring 2 can be rotated under the action of magnetic force so that the middle drain port 109 corresponds to the sealing ring drain hole 201. The purpose of doing this is:

[0039] On the one hand, the sealing ring 2 can seal the middle-layer drain port 109. When the water distributor body 1 is submerged, no impurities such as mud and sand will enter the middle-layer water injection channel 108 through the middle-layer drain port 109 to block the middle-layer water injection channel 108 or even the inside of the water distributor body 1, thereby affecting the overall service life of the water distributor body 1. When water distribution is required, the sealing ring 2 can be rotated. After the water distribution is completed, the sealing ring 2 is rotated again to stagger the sealing ring drain hole 201 and the middle-layer drain port 109, thereby sealing the middle-layer drain port 109.

[0040] On the other hand, the sealing ring 2 is rotatably arranged on the outer side of the water distributor body 1, and the outer side of the sealing ring 2 is consistent with the outer side of the water distributor body 1, so that impurities such as mud and sand will not adhere to it, ensuring the smooth diving of the water distributor body 1. At the same time, the annular sealing ring 2 will also reduce the water resistance during the rotation process, thereby improving the convenience of use;

[0041] The specific water distribution in the middle layer is as follows:

[0042] The water injection port 104 is provided with a diverter plate rotating groove 107, the sealing drive mechanism 9 comprises a wheel drive motor 901 and a wheel sealing plate 902 arranged at the output end of the wheel drive motor 901, the wheel sealing plate 902 is rotatably arranged inside the diverter plate rotating groove 107, and the middle water injection channel 108 is provided inside the diverter plate rotating groove 107, wherein when the wheel drive motor 901 is not braked, the wheel sealing plate 902 is used to seal the middle water injection channel 108, and the sealing drive mechanism The wheel seal plate 902 on the 9 is rotated inside the diverter plate rotating groove 107 by the wheel drive motor 901, and when the middle layer water distribution is not required, the middle layer water injection channel 108 is sealed by the wheel seal plate 902, so that water will not enter the middle layer drain port 109 through the middle layer water injection channel 108. When water distribution is required through the middle layer drain port 109, the wheel seal plate 902 is removed from the port of the middle layer water injection channel 108 by the wheel drive motor 901;

[0043] When the wheel drive motor 901 rotates, the wheel sealing plate 902 is driven to rotate. The transmission mechanism 7 includes a transmission gear 701 and a driving gear column 703 connected by a transmission rod 702. A driving plate groove 103 is provided inside the water distributor body 1. The magnet driving mechanism 8 is slidably arranged inside the driving plate groove 103. The transmission rod 702 penetrates the water distributor body 1 and extends to the inside of the driving plate groove 103. The bottom of the driving gear column 703 is rotatably arranged inside the driving plate groove 103 through a bearing. A driving rack 903 is fixedly arranged on the sealing driving mechanism 9. The rack 903 is used to rotate the transmission gear 701. A driving rack 903 is fixedly arranged on one side of the wheel sealing plate 902. The transmission mechanism 7 is arranged on one side of the wheel sealing plate 902. When the driving rack 903 rotates, the transmission gear 701 is driven to rotate. When the transmission gear 701 rotates, the driving gear column 703 is driven to rotate through the transmission rod 702. The driving gear column 703 on the transmission rod 702 is rotatably arranged inside the driving plate slot 103. That is to say, when the transmission gear 701 rotates, the transmission rod 702 and the driving gear column 703 will not be displaced.

[0044] After the driving gear column 703 rotates, the magnet driving mechanism 8 includes a driving plate 801, and a driving tooth 802 is fixedly provided on one side of the driving plate 801. The driving tooth 802 is meshed and connected with the driving gear column 703, and the driving gear column 703 drives the driving tooth 802 on the magnet driving mechanism 8 to rotate. The transmission mechanism 7 is used to rotate the magnet driving mechanism 8. The magnet driving mechanism 8 drives the sealing ring 2 to rotate through the second rubidium magnet 10. The second rubidium magnet 10 corresponding to the first rubidium magnet 803 will also rotate under the action of magnetic force, thereby driving the sealing ring 2 to rotate. When the sealing ring 2 rotates, the middle layer drain port 109 is aligned with the sealing ring drain hole 201. Correspondingly, a third filter screen 15 is fixedly arranged on the sealing ring drainage hole 201, and the magnet driving mechanism 8 is slidably arranged inside the driving plate groove 103. When the sealing ring 2 rotates to a certain angle, the sealing ring drainage hole 201 on the sealing ring 2 corresponds to the middle-layer drainage port 109, so that water is discharged from the middle-layer drainage port 109 to the outside of the water distributor body 1 through the sealing ring drainage hole 201. Of course, when the different-wheel sealing plate 902 rotates, the different-wheel sealing plate 902 is moved away from the upper port of the middle-layer water injection channel 108, so that water can enter the middle-layer water injection channel 108 from the water injection port 104, and be discharged to the outside of the water distributor body 1 through the sealing ring drainage hole 201;

[0045] When distributing water to the bottom layer, firstly, the wheel sealing plate 902 is rotated to the upper port of the middle layer water injection channel 108 through the wheel driving motor 901, and the middle layer water injection channel 108 is sealed. At the same time, the sealing ring drainage hole 201 seals the middle layer drainage port 109 to prevent impurities such as mud and sand from entering the interior of the water distributor body 1, and then the lower sealing plate 3 is rotated to distribute water to the bottom layer. A lower layer water injection channel 110 is opened on one side of the middle layer water injection channel 108, and the lower layer water injection channel 110 is connected with the lower layer drainage port 105. A lower layer water injection channel 110 is opened inside the water injection port 104. Water is injected from the water injection port 104 and then discharged to the interior of the lower layer drainage port 105 through the lower layer water injection channel 110. The outer side surface of the lower drainage port 105 is rotatably provided with a lower sealing plate 3, and a plurality of evenly distributed lower layer drainage holes 106 are opened on the lower drainage port 105. The lower sealing plate drainage hole 301 corresponds to the lower drainage hole 106, and the second filter screen 14 is fixedly arranged inside the lower sealing plate drainage hole 301. The lower sealing plate 3 is rotatably arranged on the outer side of the lower drainage port 105. The lower sealing plate 3 is provided with a lower sealing plate drainage hole 301 corresponding to the lower drainage hole 106. Therefore, when the lower sealing plate drainage hole 301 is aligned with the lower drainage hole 106, water can be discharged to the bottom of the water distributor body 1 through the lower drainage port 105. When the bottom water distribution is not required, the lower sealing plate 3 is rotated so that the lower sealing plate drainage hole 301 and the lower drainage hole 106 are not in the same straight line, so that the lower drainage hole 106 can be sealed. The structure is simple. Similarly, when water distribution is not required, the lower drainage hole 106 is sealed in time to prevent impurities such as mud and sand from entering the interior of the water distributor body 1, thereby improving the service life of the water distributor body 1.

[0046] The bottom layer water distribution is as follows:

[0047] A lower sealing plate rotating groove 114 is provided at the bottom of the water distributor body 1. The lower sealing plate 3 is rotatably arranged inside the lower sealing plate rotating groove 114 through the sealing plate driving mechanism 5. The lower sealing plate 3 is fixedly arranged at the bottom of the water distributor body 1 through the sealing plate driving mechanism 5. The sealing plate driving mechanism 5 includes a sealing plate rotating motor 501. The sealing plate rotating motor 501 is fixedly connected to the inside of the water injection port 104 through a motor support arm 502. The output end of the sealing plate rotating motor 501 passes through the water distributor body 1 and is fixedly connected to the lower sealing plate 3. The sealing plate driving mechanism 5 is used to rotate the lower sealing plate 3. The lower sealing plate 3 is fixedly arranged at the output end of the sealing plate driving mechanism 5. Therefore, as long as the sealing plate driving mechanism 5 rotates, the lower sealing plate 3 will rotate. When the lower sealing plate drainage hole 301 on the lower sealing plate 3 corresponds to the lower drainage hole 106, the purpose of bottom water distribution is achieved. The structure is simple. In addition to improving the convenience of use, it can also improve the sealing of the water distributor body 1.

[0048] The present invention can achieve the scope and flexibility of water distribution and lifting for the middle layer and the bottom layer. After the water distribution is completed, the sealing ring 2 can seal the middle layer drain port 109 in time, and the lower sealing plate 3 seals the bottom of the water distributor body 1. The structure is simple and prevents impurities such as mud and sand from entering the interior of the water distributor body 1. It does not affect the water injection effect and can improve the service life of the water distributor body 1.

[0049] Further, such as Figure 1 , Figure 2 as well as Figure 6 As shown, in order to improve the stability of the sealing ring 2 and the lower sealing plate 3 during rotation, a sealing ring rotation groove 101 is provided on the outer side of the water distributor body 1, and symmetrically distributed sealing ring guide grooves 102 are provided inside the sealing ring rotation groove 101. The sealing ring 2 is rotatably arranged inside the sealing ring rotation groove 101, and sealing ring guide rings 202 are fixedly arranged at both the upper and lower ends of the sealing ring 2. The sealing ring guide ring 202 is slidably arranged inside the sealing ring guide groove 102. A sealing ring guide groove 102 is provided inside the sealing ring rotation groove 101, and the sealing ring guide ring 202 on the sealing ring 2 slides inside the sealing ring guide groove 102, which can guide the sealing ring 2 and seal the water distributor body 1;

[0050] Similarly, a lower sealing plate guide groove 111 is opened inside the lower sealing plate rotation groove 114, a sealing plate guide ring 302 is fixedly set on the upper end of the lower sealing plate 3, and the sealing plate guide ring 302 is slidably set inside the lower sealing plate guide groove 111, and a lower sealing plate rotation groove 114 is opened on the outer side surface of the lower drain outlet 105, and a lower sealing plate guide groove 111 is opened inside the lower sealing plate rotation groove 114, and the sealing plate guide ring 302 on the lower sealing plate 3 is slidably set inside the lower sealing plate guide groove 111, thereby improving the rotation stability of the lower sealing plate 3 and the sealing performance of the water distributor body 1.

[0051] Furthermore, electrical energy is required during the use of the water distributor body 1. Figure 1 , Figure 2 and Figure 4As shown, a generator fixing groove 112 is provided on the side surface inside the water injection port 104, and a generator assembly 6 is fixedly arranged inside the generator fixing groove 112. The generator assembly 6 includes a generator 601, and the generator 601 is fixedly arranged inside the generator fixing groove 112 through a generator fixing bracket 602. The generator 601 is electrically connected to the sealing ring driving device 4 and the sealing plate driving mechanism 5 through a wire. The different-wheel driving motor 901 on the sealing ring driving device 4 and the sealing plate rotating motor 501 on the sealing plate driving mechanism 5 are both electrically connected to the generator 601, and the kinetic energy of water can be used to generate electricity to improve the utilization rate of resources. A generator impeller 603 is fixedly arranged at the output end of the generator 601, and the generator impeller 603 is rotatably arranged inside the water injection port 104. When water is injected into the water injection port 104 through a variable frequency speed regulating water pump, the generator 601 drives the generator impeller 603 to rotate under the action of the water flow, and then the kinetic energy of water can be converted into electrical energy, so as to fully utilize resources and improve the utilization rate of resources;

[0052] In order to prevent the failure of timely power generation, an electrical compartment 115 is provided inside the water distributor body 1. An electrical compartment 115 is provided inside the water distributor body 1. An electrically connected battery and a chip processor are fixedly provided inside the electrical compartment 115.

In addition, a chip processor is also provided inside the electrical compartment 115. The chip processor is connected to a WIFI module. The detected information can be transmitted to a wireless device such as a mobile phone by wireless means through the WIFI module, thereby improving the convenience of use.

[0053] In addition, if Figure 1 and Figure 4 As shown, a pressure sensor 11 and a flow rate sensor 12 are fixedly arranged inside the water injection port 104.

At the same time, a first filter screen 13 is fixedly provided on the threaded water injection joint 113, which can prevent impurities from entering the interior of the water distributor body 1 and improve the service life of the water distributor body 1.

[0055] like Figure 1-Figure 9 As shown, the principle of the oil well variable frequency speed regulation water injection distributor provided in this embodiment is as follows:

[0056] When water needs to be discharged from the middle-layer drain port 109, the wheel seal plate 902 on the sealing drive mechanism 9 is rotated inside the diverter plate rotating groove 107 by the wheel drive motor 901, and when the middle-layer water distribution is not needed, the middle-layer water injection channel 108 is sealed by the wheel seal plate 902, so that water will not enter the middle-layer drain port 109 through the middle-layer water injection channel 108. When water distribution needs to be performed through the middle-layer drain port 109, the wheel seal plate 902 is removed from the port of the middle-layer water injection channel 108 by the wheel drive motor 901.

[0057] A driving rack 903 is fixedly arranged on one side of the wheel sealing plate 902, and the transmission mechanism 7 is arranged on one side of the wheel sealing plate 902. When the driving rack 903 rotates, the transmission gear 701 is driven to rotate. When the transmission gear 701 rotates, the driving gear column 703 is driven to rotate through the transmission rod 702. The driving gear column 703 on the transmission rod 702 is rotatably arranged inside the driving plate groove 103. That is to say, when the transmission gear 701 rotates, the transmission rod 702 and the driving gear column 703 will not be displaced.

[0058] After the driving gear column 703 rotates, the driving teeth 802 on the magnet driving mechanism 8 are driven to rotate, and the second rubidium magnet 10 corresponding to the first rubidium magnet 803 also rotates under the action of magnetic force, thereby driving the sealing ring 2 to rotate. When the sealing ring 2 rotates to a certain angle, the sealing ring drain hole 201 on the sealing ring 2 corresponds to the middle-layer drain port 109, so water is discharged from the middle-layer drain port 109 through the sealing ring drain hole 201 to the outside of the water distributor body 1. Of course, when the different-wheel sealing plate 902 rotates, the different-wheel sealing plate 902 is removed from the upper port of the middle-layer water injection channel 108, so water can enter the middle-layer water injection channel 108 from the water injection port 104, and be discharged to the outside of the water distributor body 1 through the sealing ring drain hole 201.

[0059] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0060] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0061] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
