Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to a production and preparation device and a preparation method of a water plugging and leak plugging material for oil production. Background Art

[0002] In the process of oil production, in order to solve the problem of leakage, plugging agents are used to plug water and leak at the leaking location. According to the different plugging mechanisms, plugging agents can be divided into three types: physical plugging agents, chemical plugging agents and biological plugging agents. The operating steps of physical plugging agents are as follows: first, the physical plugging agent is mixed with water and other materials until a pumpable mixed liquid is formed, and then the mixed liquid is pumped into the leaking location to plug the leaking location.

[0003] Chinese patent CN217016486U discloses a mixing and preparing device for the production of drilling fluid plugging agents, including a tank body, a top cover fixedly connected to the upper surface of the tank body, and a first motor fixedly connected to the center position of the upper surface of the top cover. The mixing and preparing device for the production of the drilling fluid plugging agent first drives the rotating shaft to rotate through the rotating shaft of the second motor, and at this time the third stirring blade rotates synchronously, so that the raw materials can enter the tank body more quickly, and also effectively prevents the raw materials from causing the feed pipe to be blocked. When the raw materials enter the tank body, the output end of the second motor drives the fixed frame to rotate, and at this time the first stirring blade rotates synchronously, and the rotating rod and the second stirring blade also rotate at the same time, so that the raw materials can be mixed more quickly, and the stirring work efficiency is improved.

[0004] The mixing and preparing device for the production of drilling fluid plugging agent disclosed in the above-mentioned prior art can quickly mix the raw materials, thereby improving the mixing work efficiency. However, when large particles or agglomerates appear in the raw materials, the mixing and preparing device for the production of drilling fluid plugging agent cannot intercept the large particles and agglomerates, and crush and grind them. The large particles and agglomerates are only broken by beating and crushing with stirring blades. This beating and crushing method will have the problem of incomplete crushing, which reduces the uniformity of raw material mixing and further affects the plugging effect.

[0005] In view of the above problems, a production and preparation device and a preparation method of water plugging and leak-proofing materials for oil production are proposed. Summary of the invention

By adopting this device to work, the problem that when large particles or agglomerates appear in the raw materials in the above background, the mixing and preparation device for producing the above-mentioned drilling fluid plugging agent only uses stirring blades to break the large particles and agglomerates, and the problem of reduced raw material mixing uniformity and poor plugging effect due to incomplete crushing is solved.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to solve the technical problem of poor plugging effect caused by low uniformity of raw material mixing, such as Figure 1-Figure 5 and Figure 7-10 As shown, the following preferred technical solutions are provided:

[0038] A production and preparation device for water plugging and leak-proofing materials for oil production, comprising a tank body 1 and a plurality of legs 2 fixedly mounted on the bottom surface of the tank body 1, the raw materials are stirred inside the tank body 1, the legs 2 are used to provide stable support for the tank body 1, an instrument 3 is fixedly mounted on the top surface of the tank body 1, an operator can judge the working condition of the tank body 1 through the instrument 3, a power assembly 4 is fixedly mounted on the top surface of the tank body 1, the output end of the power assembly 4 is interspersed in the inner cavity of the tank body 1, the power assembly 4 is used to provide power output for the stirring process, a plurality of driving assemblies 5 and a plurality of load-bearing assemblies 6 are fixedly mounted on the outer peripheral wall of the output end of the power assembly 4, the load-bearing assemblies 6 are correspondingly arranged directly below the driving assembly 5, and the load-bearing assemblies 6 and the driving assembly 5 are meshed and connected, and mounting frames 7 are fixedly mounted on the outer side walls of the plurality of load-bearing assemblies 6 When the driving component 5 rotates, it will drive the mounting frame 7 to rotate at an appropriate angle through the load-bearing component 6, thereby causing the mounting frame 7 and the parts on the mounting frame 7 to rotate at an appropriate angle, which can reduce the fluid resistance during the stirring process, and is used to achieve higher-speed rotation and stirring. A transmission component 30 is provided on the mounting frame 7, and a plurality of meshing components 40 are slidably installed on the inner wall of the inner cavity of the tank body 1. The meshing components 40 and the transmission component 30 are correspondingly meshed and connected. The transmission component 30 is respectively fixedly mounted with a first interception plate 8 and a second interception plate 10, and the first interception plate 8 and the second interception plate 10 are symmetrically arranged. The transmission component 30 is also respectively fixedly connected with a grinding roller 9 and a rotating blade 20, and the grinding roller 9 is embedded and rotatably arranged inside the first interception plate 8, and the rotating blade 20 is embedded and rotatably arranged inside the second interception plate 10.

[0039] When the raw materials are just started to be mixed and stirred, the power assembly 4 is started to rotate counterclockwise. During the counterclockwise rotation, when the second interception plate 10 intercepts large particles or agglomerates, the large particles or agglomerates are broken once under the high-speed impact of the rotating blades 20, and the large particles or agglomerates are broken into small particles, which is beneficial to improve the mixing uniformity of the raw materials.

[0040] After the raw materials are mixed and stirred for a period of time, the power component 4 is controlled to rotate clockwise. During the clockwise rotation, the first interception plate 8 intercepts the small particles that have been crushed once. Under the grinding action of the grinding roller 9, the small particles that have been crushed once are further broken into smaller particles, thereby further improving the mixing uniformity of the raw materials.

[0041] After the raw materials are mixed and stirred clockwise for a period of time, the driving component 5 is started to rotate. During the rotation of the driving component 5, the load-bearing component 6 will drive the mounting frame 7 and the first intercepting plate 8, grinding roller 9, second intercepting plate 10, rotating blade 20 and transmission component 30 on the mounting frame 7 to rotate synchronously at an appropriate angle, so as to reduce the fluid resistance during the stirring process to achieve a higher stirring speed, and the small particles that have been crushed twice will be completely crushed into tiny particles. Since the meshing component 40 has the function of moving up and down, even if the transmission component 30 changes its angle, the transmission component 30 and the meshing component 40 can still be meshed and connected. While rotating at high speed, the transmission component 30 can still drive the grinding roller 9 to rotate to continue to crush the small particles. Through such a setting, not only the stirring speed is fast, but also the mixing uniformity is enhanced.

[0042] The tank body 1 includes a tank body 11 and a feed port 12 connected and fixedly installed on the top surface of the tank body 11 , a feed port 13 connected and fixedly installed on the outer peripheral wall of the tank body 11 , and a discharge port 14 connected and fixedly installed on the bottom surface of the tank body 11 .

[0043] The power assembly 4 includes a first motor 41 fixedly mounted on the top surface of the tank body 11 and a rotating shaft 42 fixedly mounted on the output end of the first motor 41. The rotating shaft 42 is rotatably arranged in the inner cavity of the tank body 11. The first motor 41 is used to provide power output during the stirring process, and the rotating shaft 42 is used to drive the installation frame 7 and the first intercepting plate 8, grinding roller 9, second intercepting plate 10, rotating blades 20 and transmission assembly 30 on the installation frame 7 to rotate.

[0044] The installation frame 7 includes a frame body 71 fixedly installed on the outer wall of the load-bearing component 6 , and a limit rod 72 is fixedly installed on the top surface of the inner cavity of the installation frame 7 .

[0045] The transmission assembly 30 includes a first transmission gear 301 that is rotatably installed on the outer wall of the frame 71, the first transmission gear 301 is meshed with the meshing assembly 40, and a second transmission gear 302 is fixedly installed on the other end of the first transmission gear 301. A third transmission gear 303 and a friction wheel 304 are rotatably installed on the side walls of the inner cavity of the frame 71, the second transmission gear 302 and the third transmission gear 303 are meshed with each other, and the third transmission gear 303 is transmission-connected to the friction wheel 304 via a belt 305. A transmission shaft 306 and a pair of limit columns 307 are slidably installed on the side walls of the inner cavity of the frame 71.

[0046] The transmission shaft 306 includes a fixed shaft body 3061 which is slidably installed on the side wall of the inner cavity of the frame body 71, and a limiting groove 3064 is provided on the outer peripheral wall of the fixed shaft body 3061. The lower end of the limiting rod 72 is inserted into the inner cavity of the limiting groove 3064. The first rotating shaft body 3062 and the second rotating shaft body 3063 are rotatably installed on the outer walls of both sides of the fixed shaft body 3061 respectively. A grinding roller 9 is fixedly installed on the outer wall of the first rotating shaft body 3062, and a rotating blade 20 is fixedly installed on the outer wall of the second rotating shaft body 3063. Under the cooperation of the limiting rod 72 and the limiting groove 3064, when the first rotating shaft body 3062 or the second rotating shaft body 3063 rotates, the fixed shaft body 3061 will not rotate. Through such a setting, the first rotating shaft body 3062 or the second rotating shaft body 3063 can be rotated independently, so as to achieve crushing and grinding effects respectively.

[0047] When rotating counterclockwise to break large particles or agglomerates, the friction wheel 304 is driven to rotate by the first transmission gear 301, the second transmission gear 302, the third transmission gear 303 and the belt 305. The friction wheel 304 drives the rotating blade 20 to rotate at high speed through the second rotating shaft 3063 to break the large particles or agglomerates for the first time.

[0048] After the first crushing is completed, when clockwise grinding begins, the friction wheel 304 is driven to rotate by the first transmission gear 301, the second transmission gear 302, the third transmission gear 303 and the belt 305, and the friction wheel 304 drives the grinding roller 9 to rotate through the first rotating shaft 3062, so that the small particles that have been crushed for the first time can be ground into tiny particles.

[0049] The first intercepting plate 8 comprises a first plate body 81 fixedly mounted on the outer wall of one side of the limiting column 307 , a grinding groove 82 is formed on the outer wall of the first plate body 81 , and a plurality of first filter holes 83 are formed on the side wall of the inner cavity of the grinding groove 82 .

[0050] The second intercepting plate 10 includes a second plate body 101 fixedly mounted on the outer wall on the other side of the limiting column 307, a crushing groove 102 is provided on the outer wall of the second plate body 101, and a plurality of second filter holes 103 are provided on the side wall of the inner cavity of the crushing groove 102, the aperture of the second filter hole 103 is larger than the aperture of the first filter hole 83, and during the counterclockwise rotation, the second filter hole 103 will intercept large-particle raw materials and condensates, and then the rotating blades 20 will perform the first crushing on the large-particle raw materials and condensates, and when rotating clockwise, the first filter hole 83 will intercept the particles that have been crushed for the first time, and then the grinding roller 9 will grind the particles that have been crushed for the first time to form tiny particles, which is conducive to the full mixing and stirring of the raw materials.

[0051] Specifically, when the raw materials are just started to be mixed and stirred, the first motor 41 is started to rotate counterclockwise. During the counterclockwise rotation, the first motor 41 drives the mounting frame 7 and the first intercepting plate 8, grinding roller 9, second intercepting plate 10, rotating blade 20 and transmission assembly 30 on the mounting frame 7 to rotate synchronously through the rotating shaft 42. Since the meshing assembly 40 is meshed with the first transmission gear 301, the first transmission gear 301 will rotate again during the revolution with the mounting frame 7. During the counterclockwise rotation, under the action of fluid resistance, the second intercepting plate 10 and the rotating blade 20 will slide in the direction close to the mounting frame 7, while the first intercepting plate 8 and the grinding roller 9 will slide synchronously in the direction away from the mounting frame 7. After sliding to the maximum distance, the rotating blade 20 stops sliding. At this time, the friction wheel 304 contacts the second rotating shaft 3063. The power on the first transmission gear 301 is transmitted to the friction wheel 304 through the second transmission gear 302, the third transmission gear 303 and the belt 305, and drives the friction wheel 304 to rotate. The friction wheel 304 drives the second rotating shaft 3063 to rotate. During the rotation of the second rotating shaft 3063, the rotating blade 20 will be driven to rotate at a high speed. During the counterclockwise rotation, when the second intercepting plate 10 intercepts large particles or agglomerates, the large particles or agglomerates are broken once under the high-speed striking action of the rotating blade 20, and the large particles or agglomerates are broken into small particles, which is beneficial to improve the mixing uniformity of the raw materials.

[0052] After the raw materials are mixed and stirred for a period of time, the first motor 41 is controlled to rotate clockwise. During the clockwise rotation of the first motor 41, the mounting frame 7 and the first intercepting plate 8, the grinding roller 9, the second intercepting plate 10, the rotating blade 20 and the transmission assembly 30 on the mounting frame 7 will be driven to rotate synchronously. Since the meshing assembly 40 is meshed and connected with the first transmission gear 301 accordingly, the first transmission gear 301 will rotate again during the process of revolving with the mounting frame 7. During the clockwise rotation, under the action of fluid resistance, the second intercepting plate 10 and the rotating blade 20 will slide in the direction away from the mounting frame 7, while the first intercepting plate 8 and the grinding roller 9 will slide synchronously in the direction close to the mounting frame 7. The plate 8 and the grinding roller 9 stop sliding after sliding to the maximum distance. At this time, the friction wheel 304 contacts the first rotating shaft 3062. The power on the first transmission gear 301 is transmitted to the friction wheel 304 through the second transmission gear 302, the third transmission gear 303 and the belt 305, and drives the friction wheel 304 to rotate. The friction wheel 304 drives the first rotating shaft 3062 to rotate. During the rotation of the first rotating shaft 3062, the grinding roller 9 will be driven to rotate at a high speed. During the clockwise rotation, the first intercepting plate 8 will intercept the small particles that have been crushed once. Under the grinding action of the grinding roller 9, the small particles that have been crushed once will be further crushed into smaller particles, thereby further improving the mixing uniformity of the raw materials.

[0053] In order to solve the technical problems of large resistance of high-speed stirring fluid, causing instability of the stirring device and energy consumption, such as Figure 3-Figure 10 As shown, the following preferred technical solutions are provided:

[0054] The driving assembly 5 includes a second motor 51 fixedly mounted on the outer wall of the rotating shaft 42 , and an output end of the second motor 51 is fixedly connected to a driving gear 52 .

[0055] The load-bearing component 6 includes a mounting frame 61 fixedly mounted on the outer peripheral wall of the rotating shaft 42 , a driven gear 62 is rotatably mounted on the outer side wall of the mounting frame 61 , the driven gear 62 is meshedly connected with the driving gear 52 , and the frame 71 is fixedly mounted on the outer side wall of the driven gear 62 .

[0056] The meshing assembly 40 includes a pair of fixed blocks 401 fixedly mounted on the inner cavity side wall of the tank body 11, and a ring 402 is slidably mounted on the two fixed blocks 401. The two fixed blocks 401 and the ring 402 are elastically connected by springs 403 respectively. A plurality of tooth blocks 404 are fixedly mounted on the top surface of the ring 402. The plurality of tooth blocks 404 are arranged in a circular array, and the tooth blocks 404 are meshedly connected with the first transmission gear 301.

[0057] Specifically, after the raw materials are mixed and stirred clockwise for a period of time, the second motor 51 is started to rotate. During the rotation of the second motor 51, the driving gear 52 and the driven gear 62 drive the mounting frame 7 and the first intercepting plate 8, the grinding roller 9, the second intercepting plate 10, the rotating blades 20 and the transmission assembly 30 on the mounting frame 7 to rotate synchronously at an appropriate angle, so as to reduce the fluid resistance during the stirring process to achieve a higher stirring speed. The reduced fluid resistance is conducive to stable stirring work. In addition, the reduced fluid resistance is also conducive to saving electric energy. The tiny particles that have been crushed twice are completely crushed into tiny particles. Since the transmission assembly 30 changes the angle, The first transmission gear 301 will also move upward. During the upward movement of the first transmission gear 301, the ring 402 and the tooth block 404 will also move upward under the elastic force of the spring 403, so that the tooth block 404 is always in a meshing state with the first transmission gear 301. Through such an arrangement, while rotating at a high speed, the first transmission gear 301 can still drive the grinding roller 9 to rotate through the second transmission gear 302, the third transmission gear 303, the friction wheel 304 and the belt 305, and continue to crush the small particles. The above arrangement not only has a fast stirring speed and high stirring efficiency, but also can enhance the uniformity of mixing, thereby maintaining a good plugging effect.

[0058] In order to further better explain the above embodiment, the present invention also provides an implementation scheme: a method for preparing a water plugging and leak-proof material for oil production, comprising the following steps:

[0059] Step 1: Pour the raw materials into the interior of the tank body 11 through the feed port 12, and start the power assembly 4 to rotate counterclockwise.

[0060] Step 2: After the power assembly 4 finishes rotating counterclockwise, control the power assembly 4 to rotate clockwise.

[0061] Step three: After the power component 4 finishes rotating clockwise, the control driving component 5 drives the mounting frame 7 and the first intercepting plate 8, grinding roller 9, second intercepting plate 10, rotating blades 20 and transmission component 30 on the mounting frame 7 to rotate to a suitable angle through the load-bearing component 6, and increases the rotation speed of the power component 4.

[0062] Step 4: After the mixing and stirring is completed, the material is discharged through the discharge port 14.

[0063] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
