Description

Technical Field

[0001] The invention relates to the field of breaker preparation, and more specifically to a fracturing fluid capsule breaker preparation device. Background Art

[0002] Fracturing fluid is one of the key working fluids in oil and gas production and is often used in hydraulic fracturing operations. Capsule breakers play a role in delayed breaking in fracturing fluids. Capsule breakers are wrapped in special capsules and can release breakers in a concentrated manner under certain conditions, thereby effectively reducing the viscosity of the fracturing fluid and reducing damage to the formation.

[0003] The preparation method of the capsule breaker includes multiple steps, among which the preparation processes of the organic solution, emulsification polymerization, encapsulation and drying are the most critical, and the drying of the capsule breaker is an important step in the preparation process, which is related to the stability, release performance and final application effect of the breaker. In the prior art, a Chinese patent with the authorization announcement number CN211316894U discloses a heating device for preparing a petroleum capsule breaker, which avoids overheating and decomposition of the ammonium persulfate crystals by not directly contacting the electric heating tube with the ammonium persulfate crystals, and at the same time fully heats and dries the ammonium persulfate crystals at the bottom of the tank, thereby improving the drying effect of the capsule breaker to a certain extent;

[0004] When the existing capsule breaker drying device is working, the capsule breaker is heated and dried indirectly through the heating tube and the tank body. Although it can reduce the probability of overheating and denaturation of the capsule breaker to a certain extent, in actual work, the drying temperature will directly affect the preparation quality of the capsule breaker. Although the risk of excessive temperature of the capsule breaker can be reduced by adopting indirect heating, the temperature of the inner wall of the tank body will be higher than the temperature inside the tank body, so that the temperature of the part of the capsule breaker directly in contact with the inner wall of the tank will be inconsistent with the temperature of the capsule breaker in other parts of the tank body, thereby affecting the drying uniformity of the capsule breaker. Mixing capsule breakers with different dryness will also prolong the drying time of the capsule breaker, thereby affecting the drying efficiency of the capsule breaker. Summary of the invention

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 A fracturing fluid capsule breaker preparation device comprises a processing tank 11, a collecting barrel 17 is fixedly connected to the lower end of the processing tank 11, an air outlet pipe 16 is fixedly connected to the upper end of the processing tank 11, a drying component is arranged inside the processing tank 11, and the drying component comprises a feeding part and a crushing part;

[0035] The lower end of the gas outlet pipe 16 penetrates the inner side of the processing tank 11, and the material conveying part includes a material guide plate 24 fixedly connected to the inner surface of the processing tank 11, and the material guide plate 24 is distributed in a spiral shape, and the material guide plate 24 is fixedly connected to the outer surface of the gas outlet pipe 16;

[0036] The crushing part includes a discharge trough 25 opened on the outer surface of the guide plate 24, the lower end of the air outlet pipe 16 is fixedly connected to the gas collecting hood 27, the outer surface of the gas collecting hood 27 is fixedly connected to the push rod 26, the end of the push rod 26 away from the gas collecting hood 27 is fixedly connected to the inner surface of the processing tank 11, and the push rod 26 is located directly below the discharge trough 25.

[0037] By adopting the above technical solution, in the production and preparation process of the fracturing fluid capsule breaker, the capsule breaker needs to be dried into a stable solid form for easy packaging and transportation. For this purpose, a drying component is set. When the agglomerated capsule breaker is dried, warm gas is injected into the processing tank 11 from the lower side of the collecting barrel 17, and then the agglomerated capsule breaker is added to the upper surface of the guide plate 24. The guide plate 24 is distributed in a spiral shape, so that the agglomerated capsule breaker slides down along the guide plate 24 under the action of gravity. When the capsule breakers move to the discharge groove 25 on the surface of the guide plate 24, some of the capsule breakers will fall downward through the discharge groove 25, while the remaining capsule breakers will continue to slide downward along the surface of the spiral guide plate 24 and continue to fall downward through the discharge grooves 25 distributed in an annular array on the surface of the guide plate 24, so that the breakers on the surface of the guide plate 24 can gradually fall through the discharge groove 25. In the process of falling, the capsule breakers will contact the top rod 26 on the lower side of the discharge groove 25, and the lumpy capsule breakers will be After the glue agent collides with the push rod 26, it will be broken, thereby breaking and loosening the capsule breaker and reducing the volume of the capsule breaker so that the capsule breaker can contact with the warm gas more fully. The capsule breaker that has been initially broken continues to fall under the action of gravity, and the warm gas will flow upward from the lower side of the processing tank 11. The capsule breaker is dried by the contact between the warm gas and the capsule breaker, which can not only reduce the risk of overheating of the capsule breaker, but also keep the drying uniformity of the capsule breaker consistent. After the push rod 26 is hit by the capsule breaker, a certain amplitude of vibration will be generated, and the vibration will be transmitted to the air outlet pipe 16 and the guide plate 24 through the gas collecting hood 27, so as to accelerate the sliding of the capsule breaker on the surface of the guide plate 24, thereby further improving the feeding effect of the capsule breaker, and part of the warm gas will diffuse to the upper side of the guide plate 24 through the discharge chute 25 to preheat the capsule breaker, thereby effectively shortening the drying time of the capsule breaker, thereby improving the drying efficiency of the capsule breaker to a certain extent.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the outer surface of the collecting barrel 17 is fixedly connected with a support leg 12, and a support rod 13 is fixedly connected between adjacent support legs 12. The inner surface of the collecting barrel 17 is fixedly connected with a guide plate 53, and the guide plate 53 is fixedly connected with an air guide pipe 15 on the side away from the collecting barrel 17, and the lower end of the air guide pipe 15 passes through the outside of the collecting barrel 17.

[0039] The outer surface of the air guide pipe 15 is fixedly connected to an air inlet pipe 14, the upper side of the outer surface of the processing tank 11 is fixedly connected to a feed pipe 18, the air inlet pipe 14 is connected to the hot blast furnace gas pipeline, the collecting barrel 17 is funnel-shaped, and the lower side of the inner surface of the processing tank 11 is fixedly connected to a limiting plate 19, and the limiting plate 19 is annular.

[0040] A pull rod 21 is fixedly connected to the inner surface of the air guide pipe 15, a column 22 is fixedly connected to the outer surface of the upper end of the pull rod 21, a guide seat 23 is fixedly connected to the upper end of the column 22, and the outer surface of the upper end of the guide seat 23 is arc-shaped. The discharge troughs 25 and the push rods 26 are in several groups and distributed in a ring array. The air collecting hood 27 is trumpet-shaped, and the push rods 26 are made of elastic material.

[0041] By adopting the above technical solution, the support leg 12 supports the processing tank 11 through the collecting barrel 17, and the support rod 13 can effectively improve the support stability of the support leg 12. When the capsule breaker drying preparation device is working, the capsule breaker in a lump form is first added to the upper surface of the guide plate 24 through the feed pipe 18, and then the warm gas is injected into the air guide pipe 15 through the air intake pipe 14. The warm gas is preliminarily treated before entering the air intake pipe 14, so that the intake temperature of the warm gas is maintained in the range of 60 to 70 degrees Celsius. The warm gas flows upward inside the air guide pipe 15, and the air guide pipe 15 is fixed to the column 22 by the pull rod 21. The guide seat 23 is supported by the column 22, and the upper surface of the guide seat 23 is in an arc shape so that the capsule breaker can quickly slide down from the upper surface of the guide seat 23. The warm gas inside the air guide pipe 15 will diffuse from the gap between the air guide pipe 15 and the guide seat 23 to the inside of the processing tank 11. The warm gas will fully contact with the capsule breaker during the upward flow, so that the capsule breaker is dried by the warm gas. As the gas continues to flow upward, the gas is collected and guided by the gas collecting hood 27 to the inside of the gas outlet pipe 16, and then discharged to the outside of the processing tank 11 through the gas outlet pipe 16 for further recovery.

[0042] like Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, a return material assembly is provided on the inner side of the collecting barrel 17, and the return material assembly includes a baffle 52 fixedly connected to the inner surface of the collecting barrel 17, and the baffle 52 and the guide plate 53 are both distributed in a circular ring shape. A discharge trough 51 is provided on the outer surface of the collecting barrel 17, and the discharge trough 51 is located on the upper side of the baffle 52. A collecting pipe 58 is fixedly connected to the outer surface of the collecting barrel 17, and the collecting pipe 58 is in a circular ring shape. A discharge pipe 581 is fixedly connected to the outer surface of the lower end of the collecting pipe 58, and a heat conducting plate 55 is fixedly connected to the outer surface of the air guide pipe 15. The number of the heat conducting plates 55 is several groups and distributed in a ring array.

[0043] The outer surface of the guide plate 53 is provided with a discharge trough 2 54, and the number of the discharge troughs 1 51 and 54 is several groups and distributed in a ring array. The lower end of the collecting barrel 17 is fixedly connected to a guide pipe 59, and the lower end of the guide pipe 59 is fixedly connected to the outer surface of the air guide pipe 15. The outer surface of the guide pipe 59 is fixedly connected to a return pipe 57, and the return pipe 57 is a U-shaped structure. The upper end of the return pipe 57 passes through the inner side of the processing tank 11. The inner surface of the processing tank 11 is fixedly connected to a suction pump 56, and the upper end of the return pipe 57 is connected to the suction pump 56.

[0044] By adopting the above technical solution, the capsule breaker continues to fall downward under the action of gravity after being dried by hot air, and some capsule breaker particles will fall on the outer surface of the limiting plate 19 and slide downward under the guidance of the limiting plate 19. The guide seat 23 can effectively prevent the capsule breaker from entering the air guide pipe 15. When the warm gas is ejected from between the air guide pipe 15 and the guide seat 23, it will blow the capsule breaker, which will not only further dry the capsule breaker, but also completely dry the capsule breaker particles. The particles will fall on the upper surface of the baffle 52 under the action of the hot air, and then the capsule breaker particles will enter the interior of the collecting pipe 58 through the discharge trough 51 under the guidance of the baffle 52, and then be discharged through the discharge pipe 581 at the lower side of the collecting pipe 58 for subsequent packaging processing. The weight of some capsule breakers that are not completely dried and the lumpy capsule breakers is greater than that of completely dried capsule breakers. Therefore, the horizontal displacement distance under the action of the hot air is smaller. At this time, the capsule breakers that are not completely dried and the lumpy capsule breakers are The capsule breaker will fall on the upper surface of the guide plate 53 under the action of gravity, and then the capsule breaker will fall into the inside of the collecting barrel 17 through the discharge groove 54 on the surface of the guide plate 53. When the warm gas flows from the inside of the air guide pipe 15, part of the heat will be transferred to the heat conduction plate 55 on the surface of the air guide pipe 15. After entering the inside of the collecting barrel 17, the capsule breaker will contact the outer surface of the heat conduction plate 55, and the undried capsule breaker will be further dried by the heat conduction plate 55. Then the capsule breaker enters the guide pipe under the action of gravity. 59, and at the same time, the extraction pump 56 is started to operate, and the extraction pump 56 sucks the undried capsule breaker from the inside of the guide pipe 59 to the upper surface of the guide plate 24 through the return pipe 57, and continues to perform hot air drying. By separating the dried capsule breaker in time, the drying speed of the capsule breaker can be effectively improved, thereby ensuring that the capsule breaker can be fully dried, which can not only improve the uniformity of the finished particles of the capsule breaker, but also further improve the preparation and processing quality of the capsule breaker.

[0045] like Figure 4 and Figure 7As shown, a material shifting assembly is provided on the inner side of the air outlet pipe 16, and the material shifting assembly includes a limiting rod 33 fixedly connected to the inner surface of the air outlet pipe 16, and a rotating sleeve 32 is fixedly connected to the outer surface of the limiting rod 33, and a rotating shaft 31 is rotatably connected to the inner surface of the rotating sleeve 32, and a paddle 34 is fixedly connected to the outer surface of the rotating shaft 31.

[0046] The outer surface of the rotating shaft 31 is fixedly connected with a connecting seat 35, and the outer surface of the connecting seat 35 is fixedly connected with a material-pickup piece 36. The number of the material-pickup pieces 36 is several groups and distributed in a ring array. The material-pickup pieces 36 are made of lightweight materials.

[0047] By adopting the above technical scheme, when the warm gas is discharged to the outside of the processing tank 11 through the air outlet pipe 16, the gas will drive the rotating shaft 31 to rotate through the paddle 34 during the upward flow, and the air blowing pipe fixes and supports the rotating sleeve 32 through the limit rod 33, so that the rotating sleeve 32 supports the rotating shaft 31, so that the rotation of the rotating shaft 31 is more stable, and the rotating shaft 31 drives the material shifting piece 36 to rotate through the connecting seat, and the capsule breaker will contact the material shifting piece 36 during the falling process, so that the capsule breaker is impacted and broken by the material shifting piece 36, thereby effectively reducing the volume of the capsule breaker, so that the capsule breaker can fully contact with the warm gas, thereby further improving the drying effect of the capsule breaker.

[0048] like Figure 4 and Figure 6 As shown, the lower end of the rotating shaft 31 is fixedly connected to a fixed disk 41, and the outer surface of the lower end of the fixed disk 41 is fixedly connected to a blocking rod 43, and the number of the blocking rods 43 is several groups and distributed in a ring array, and the inner surface of the processing tank 11 is fixedly connected to a bracket 46, and the outer surface of the upper end of the bracket 46 is rotatably connected to a movable rod 42, and the upper side of the outer surface of the movable rod 42 is fixedly connected to a contact plate 44, and the number of the contact plates 44 is several groups and distributed in a ring array, and the outer surface of the contact plate 44 is in sliding contact with the blocking rod 43.

[0049] The outer surface of the movable rod 42 is fixedly connected to a friction wheel 1 45, the outer surface of the bracket 46 is rotatably connected to a rotating shaft 2 48, the upper end of the rotating shaft 2 48 is fixedly connected to a friction wheel 2 47, the outer surface of the friction wheel 1 45 is in rotational contact with the friction wheel 2 47, the lower end of the rotating shaft 2 48 is fixedly connected to a connecting seat 2 49, and the outer surface of the connecting seat 2 49 is fixedly connected to a material shifting piece 2 491.

[0050] By adopting the above technical solution, the rotating shaft 1 31 will drive the fixed plate 41 to rotate synchronously during the rotation process, thereby driving the blocking rod 43 to make a circular motion through the fixed plate 41, and the processing tank 11 will support the movable rod 42 through the bracket 46. The blocking rod 43 will rotate and contact with the contact plate 44 during the rotation process, thereby driving the movable rod 42 to rotate through the contact plate 44. The movable rod 42 will drive the friction wheel 1 45 to rotate synchronously during the rotation process, and the friction wheel 2 47 will drive the friction wheel 2 47 to rotate synchronously by rotating in contact with the friction wheel 1 45, thereby Wheel 2 47 drives shaft 2 48 to rotate synchronously, and shaft 2 48 drives paddle piece 2 491 to rotate synchronously through connecting seat 2 49. Paddle piece 1 36 and paddle piece 2 491 rotate at different speeds, so that paddle piece 1 36 and paddle piece 2 491 can effectively contact and collide with the lumpy capsule breaker, which can not only improve the crushing effect of the capsule breaker, but also prolong the residence time of the capsule breaker in the processing tank 11, so that the capsule breaker has sufficient time to contact with the warm gas, thereby ensuring the drying quality of the capsule breaker.

[0051] Working principle: When the capsule breaker is dried, firstly, the lumpy capsule breaker is added to the upper surface of the guide plate 24 through the feed pipe 18, and part of the capsule breaker will fall downward through the discharge chute 25. During the falling process, the capsule breaker will contact the top rod 26 on the lower side of the discharge chute 25, and the lumpy capsule breaker will be broken after colliding with the top rod 26. At the same time, warm gas is injected into the air guide pipe 15 through the air inlet pipe 14. During the upward flow of the warm gas, it will fully contact the capsule breaker, so that the capsule breaker is dried by the warm gas. During the falling process, the capsule breaker will contact the material-pickup sheet 1 36 and the material-pickup sheet 2 4 91 is in contact with each other, so that the material-discharging piece 1 36 and the material-discharging piece 2 491 can effectively contact and collide with the agglomerated capsule breakers, thereby further reducing the volume of the capsule breakers and allowing the capsule breakers to fully contact with the warm gas, thereby further improving the drying effect of the capsule breakers. Some of the capsule breakers that are not completely dried and the agglomerated capsule breakers will be collected inside the collecting barrel 17, and the undried capsule breakers will be further dried by the heat conducting plate 55. The suction pump 56 will suck the undried capsule breakers from the inside of the guide pipe 59 to the upper surface of the guide plate 24 through the return pipe 57, and continue to perform hot air drying.
