Description

Technical Field

[0001] This application relates to the field of polymerization reactor technology, specifically a polymerization reactor for drilling fluid production. Background Technology

[0002] Drilling fluid is a general term for various circulating fluids that fulfill the needs of drilling operations through multiple functions. It is considered the lifeblood of drilling, also known as borehole flushing fluid. Its main function is to design drilling fluid formulations to ensure the smooth completion of drilling operations within the wellbore to reach the desired oil formation. It is primarily suitable for unstable rock formations with loose, fractured, easily collapsing, or water-swelling and spalling characteristics.

[0003] An existing patent (publication number: CN215086784U) discloses a polymerization reactor for drilling fluid production, including a reactor body, a reactor lid fixed to the top of the reactor body, a feed pipe connected to the top of the reactor lid, a discharge pipe connected to the bottom of the reactor body, a motor fixed in the middle of the top of the reactor lid, and a rotating shaft driven by the output shaft of the motor. The rotating shaft is equipped with a defoaming device and a stirring device. The defoaming device includes a bubble-absorbing plate, a defoaming paddle assembly, and a defoaming mesh arranged sequentially along the length of the rotating shaft. The rotating shaft is rotatably connected to the bubble-absorbing plate through bearings. The bottom of the bubble-absorbing plate has multiple bubble-absorbing holes. Bubble-absorbing tubes are fixed at both ends of the top of the bubble-absorbing plate. The bubble-absorbing tubes pass through the reactor lid and are connected to a connecting pipe. A defoaming box is fixed on the outer wall of the upper part of the reactor body. A suction pump is fixed on the top of the defoaming box. One end of the connecting pipe is connected to the inlet end of the suction pump. The outlet end of the suction pump is connected to the defoaming box through a drain pipe. A return pipe is connected between the bottom of the defoaming box and the interior of the reactor body. It has high defoaming and defoaming efficiency and can effectively suppress the generation of bubbles in the reactor.

[0004] While the apparatus in the aforementioned comparative documents can improve defoaming efficiency, its conventional stirring structure results in a monotonous stirring effect, leading to uneven mixing and low reaction efficiency. To address these issues, a drilling fluid production polymerization reactor is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a drilling fluid production polymerization reactor, which solves the problems of uneven mixing and low reaction efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a drilling fluid production polymerization reactor, comprising a polymerization reactor body, a top cover, a stirring assembly, and a temperature control assembly. The stirring assembly includes a servo motor fixedly connected to the bottom surface of the polymerization reactor body, and a main shaft fixedly connected to the output shaft end of the servo motor. The outer surface of the main shaft is fixedly connected with uniformly distributed first and second stirring blades. The interior of the polymerization reactor body is provided with a flow guide tube. The outer surface of the flow guide tube is fixedly connected with uniformly distributed connecting frames. The flow guide tube is fixedly connected to the inner wall of the polymerization reactor body through multiple connecting frames. The outer surface of the flow guide tube has uniformly distributed oblique flow guide holes. The direction of the oblique flow guide holes is opposite to the direction of rotation of the main shaft. Multiple first and second stirring blades correspond to the positions of multiple oblique flow guide holes, and each first and second stirring blade maintains a certain distance from the inner wall of the flow guide tube.

[0007] The above scheme optimizes the mixing structure through the set stirring components, achieving uniform mixing and high-efficiency reaction. When the servo motor starts, it can drive the first and second stirring paddles to rotate. The multi-layered first and second stirring paddles, together with the guide tube, form strong shearing and circulating flow, making the material mix more uniform and the reaction more complete. In addition, the guide tube is provided with oblique guide holes opposite to the rotation direction of the main shaft, which can effectively reduce stirring resistance and energy consumption. The set temperature control components can control and adjust the temperature inside the polymerization reactor, optimizing the drilling fluid production environment.

[0008] Furthermore, a set of auxiliary stirring blades is fixedly connected to both the top and bottom of the main shaft, and the guide tube is located between the two sets of auxiliary stirring blades.

[0009] With the above scheme, when the main shaft rotates, it can drive two sets of auxiliary stirring blades to rotate. The rotation of the auxiliary stirring blades can play a role in assisting stirring and mixing, which is more practical.

[0010] Furthermore, the temperature control component includes a jacket formed in the inner wall of the polymerization reactor body, the interior of which is filled with heat-conducting oil, and a heating component and a cooling component are mounted on the outer surface of the polymerization reactor body via a bracket.

[0011] The above scheme allows the heating component to heat the heat transfer oil and the cooling component to cool it, thus facilitating the heating or cooling of the inner wall of the polymerization reactor.

[0012] Furthermore, the heating and cooling components are connected to two circulation pipes on the side closest to each other, and the four valves are all connected to the interior of the interlayer. Each circulation pipe segment is equipped with a valve.

[0013] The valves provided by the above scheme can easily control the direction of heat transfer oil flow, thereby facilitating the switching of the temperature control components between heating and cooling.

[0014] Furthermore, positioning bolts are installed at the edges of the top cover, and the top cover is positioned on the top of the polymerization reactor body by the positioning bolts. A temperature sensor is installed on the bottom surface of the top cover, and the heating and cooling components are electrically connected to the temperature sensor.

[0015] The above scheme allows for easy disassembly and assembly of the top cover and the polymerization reactor body, facilitating regular cleaning of the inner wall of the polymerization reactor body. The temperature sensor can monitor the internal temperature of the polymerization reactor body in real time, facilitating temperature control and optimizing the drilling fluid production environment.

[0016] Furthermore, a controller is fixedly connected to the outer surface of the polymerization reactor body, and the electrical components inside the stirring assembly and temperature control assembly are all electrically connected to the controller.

[0017] The above-described controller can control the electrical components inside the stirring and temperature control components, simplifying the operation process.

[0018] Furthermore, the top of the top cover is equipped with two feed ports, the output end of each feed port is connected to the interior of the polymerization reactor body, and a liquid outlet is installed on one side of the polymerization reactor body, the input end of the liquid outlet is connected to the interior of the polymerization reactor body.

[0019] The above scheme allows for the convenient addition of drilling fluid base and additives to the polymerization reactor body through the feed inlet, and the convenient discharge of the mixed drilling fluid through the outlet.

[0020] Furthermore, four L-shaped support rods are fixedly connected to the outer surface of the polymerization reactor body, and an anti-slip pad is fixedly connected to the bottom of each L-shaped support rod.

[0021] The above-mentioned design, with its L-shaped support rods and anti-slip pads, improves the stability of the polymerization reactor body when placed on the ground, thus contributing to the stable production of drilling fluid.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This drilling fluid production polymerization reactor features an optimized stirring structure through its set stirring components, achieving uniform mixing and high-efficiency reaction. When the servo motor starts, it drives the first and second stirring paddles to rotate. The multi-layered first and second stirring paddles, in conjunction with the guide tube, form strong shearing and circulating flow, making the material mixing more uniform and the reaction more complete. Furthermore, the guide tube has oblique guide holes that are opposite to the rotation direction of the main shaft, which can effectively reduce stirring resistance and lower energy consumption. The set temperature control components can control and adjust the temperature inside the polymerization reactor. The jacket is filled with heat transfer oil, and heating or cooling is achieved through heating and cooling components. Combined with temperature sensors and controllers, the temperature inside the polymerization reactor can be controlled and adjusted to optimize the drilling fluid production environment.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a drilling fluid production polymerization reactor includes a polymerization reactor body 1, a top cover 2, a stirring assembly 4, and a temperature control assembly 5. The stirring assembly 4 includes a servo motor 401 fixedly connected to the bottom surface of the polymerization reactor body 1, and a main shaft 402 fixedly connected to the output shaft end of the servo motor 401. The outer surface of the main shaft 402 is fixedly connected with uniformly distributed first stirring paddles 403 and second stirring paddles 404. The first stirring paddles 403 and second stirring paddles 404 are staggered, and adjacent first stirring paddles 403 and second stirring paddles 404 are in opposite directions. The reason for the opposite direction is to form an up-and-down circulating flow when the first stirring paddles 403 and second stirring paddles 404 rotate, thereby enhancing the mixing effect. The polymerization reactor body 1 is provided with a flow guide cylinder 405. The first stirring paddles 403 and second stirring paddles 404 are both located inside the flow guide cylinder 405. When the first stirring paddles 403 and second stirring paddles 404 rotate, they can form an annular channel with the flow guide cylinder 405, thereby improving the mixing efficiency and reaction efficiency through strong shearing and circulating flow.

[0033] Please see Figure 3 , Figure 4 and Figure 5 The outer surface of the guide tube 405 is fixedly connected with evenly distributed connecting frames 406. The guide tube 405 is fixedly connected to the inner wall of the polymerization reactor body 1 through multiple connecting frames 406. The outer surface of the guide tube 405 has evenly distributed oblique guide holes 407. The direction of the oblique guide holes 407 is opposite to the direction of rotation of the main shaft 402, which limits the positional relationship of the oblique guide holes 407 and can effectively reduce stirring resistance and energy consumption. Multiple first stirring blades 403 and second stirring blades 404 correspond to the positions of multiple oblique guide holes 407 respectively. Each first stirring blade 403 and second stirring blade 404 maintains a certain distance from the inner wall of the guide tube 405. A set of auxiliary stirring blades 408 are fixedly connected to the top and bottom of the main shaft 402. The guide tube 405 is located between the two sets of auxiliary stirring blades 408. When the main shaft 402 rotates, it can drive the two sets of auxiliary stirring blades 408 to rotate. The rotation of the auxiliary stirring blades 408 can play an auxiliary stirring and mixing effect, which is more practical.

[0034] Please see Figure 1 , Figure 2 and Figure 3The temperature control component 5 includes a jacket 501 formed in the inner wall of the polymerization reactor body 1. The jacket 501 is filled with heat transfer oil. A heating component 502 and a cooling component 503 are mounted on the outer surface of the polymerization reactor body 1 via a bracket. The heating component 502 and the cooling component 503 are existing devices and are not the objects to be protected in this application. Therefore, the internal structure and working principle of the heating component 502 and the cooling component 503 will not be described. However, it should be understood that the heating component 502 can heat the heat transfer oil and the cooling component 503 can cool the heat transfer oil, thereby facilitating the heating or cooling of the inner wall of the polymerization reactor body 1.

[0035] Please see Figure 2 , Figure 3 and Figure 4 The heating component 502 and the cooling component 503 are connected to two circulation pipes 504 on their adjacent sides. Four valves 505 are connected to the interior of the jacket 501. Each circulation pipe 504 has a valve 505 installed at its end. The valves 505 can be used to control the direction of heat transfer oil flow, thereby facilitating the switching of heating or cooling by the temperature control component 5. Positioning bolts 6 are installed on the edge of the top cover 2, and the top cover 2 is positioned on the top of the polymerization reactor body 1 by the positioning bolts 6. A temperature sensor 506 is installed on the bottom surface of the top cover 2. The heating component 502 and the cooling component 503 are electrically connected to the temperature sensor 506. The positioning bolts 6 allow for easy disassembly and assembly between the top cover 2 and the polymerization reactor body 1, facilitating regular cleaning of the inner wall of the polymerization reactor body 1. The temperature sensor 506 can monitor the internal temperature of the polymerization reactor body 1 in real time, facilitating temperature control and optimizing the drilling fluid production environment.

[0036] Please see Figure 1 , Figure 2 and Figure 3A controller 3 is fixedly connected to the outer surface of the polymerization reactor body 1. The electrical components inside the stirring assembly 4 and the temperature control assembly 5 are all electrically connected to the controller 3. The controller 3 can control the operation of the electrical components inside the stirring assembly 4 and the temperature control assembly 5, simplifying the operation process. Two feed ports 7 are installed on the top of the top cover 2. The output end of each feed port 7 is connected to the interior of the polymerization reactor body 1. A liquid outlet 9 is installed on one side of the polymerization reactor body 1. The input end of the liquid outlet 9 is connected to the interior of the polymerization reactor body 1. The feed ports 7 can be used to easily add drilling fluid base fluid and additives to the polymerization reactor body 1. The liquid outlet 9 can be used to easily discharge the mixed drilling fluid. Four L-shaped support rods 8 are fixedly connected to the outer surface of the polymerization reactor body 1. The bottom of each L-shaped support rod 8 is fixedly connected to an anti-slip pad. The L-shaped support rods 8 and the anti-slip pads can improve the stability of the polymerization reactor body 1 when placed on the ground, which is beneficial to the stable production of drilling fluid.

[0037] In this embodiment, a drilling fluid production polymerization reactor, through the set stirring component 4, can optimize the stirring structure to achieve uniform mixing and high-efficiency reaction. When the servo motor 401 is started, it can drive the first stirring paddle 403 and the second stirring paddle 404 to rotate. The multi-layered first stirring paddle 403 and second stirring paddle 404 cooperate with the guide tube 405 to form strong shearing and circulating flow, making the material mixing more uniform and the reaction more complete. Furthermore, the guide tube 405 is provided with oblique guide holes 407 opposite to the rotation direction of the main shaft 402, which can effectively reduce stirring resistance and reduce energy consumption. The set temperature control component 5 can control and adjust the temperature inside the polymerization reactor body 1. The jacket 501 is filled with heat transfer oil, and heating or cooling is achieved through the heating component 502 and the cooling component 503. Combined with the temperature sensor 506 and the controller 3, the temperature inside the polymerization reactor body 1 can be controlled and adjusted to optimize the drilling fluid production environment.

[0038] The working principle of the above embodiment is as follows: During use, drilling fluid base fluid and additives are added to the polymerization reactor body 1 through two feed ports 7 for stirring and mixing reaction. Then, the servo motor 401 is started. When the servo motor 401 is started, it drives the main shaft 402, the first stirring paddle 403 and the second stirring paddle 404 to rotate. When the first stirring paddle 403 and the second stirring paddle 404 rotate, they can drive the material to circulate in the annular channel formed between the first stirring paddle 403, the second stirring paddle 404 and the guide cylinder 405. At the same time, the inclined guide holes 407 opened on the surface of the guide cylinder 405 guide the material from the guide cylinder. The internal discharge of the cylinder 405 creates a strong shearing and mixing effect, thereby achieving uniform mixing and efficient reaction. When the main shaft 402 rotates, it also drives two sets of auxiliary stirring blades 408 to rotate, further optimizing the uniformity and efficiency of stirring, making it more practical. The temperature sensor 506 can detect the temperature inside the polymerization reactor body 1 in real time. The heating component 502 or the cooling component 503 can heat or cool the material inside the polymerization reactor body 1 as needed, thereby optimizing the production environment of the drilling fluid and improving the production quality. Finally, the produced drilling fluid can be discharged through the outlet 9.
