Description

Technical Field

[0001] This utility model belongs to the field of oil displacement agents, specifically relating to a nano-oil displacement agent production device. Background Technology

[0002] Oil displacement agents are additives used in oil drilling and extraction to enhance crude oil recovery. Nano-oil displacement agent production equipment is a new type of technology designed to improve oilfield extraction efficiency and reduce production costs.

[0003] Compared with traditional oil displacement agents, nano-oil displacement agents have higher efficiency and lower dosage in production equipment. However, there are still some problems when using nano-oil displacement agent production equipment. For example, the modification of oil displacement agents requires a long time, resulting in low modification efficiency. At the same time, substances are prone to sticking to the inner wall of the tank during the modification process, resulting in residues remaining on the tank wall.

[0004] In summary, there is an urgent need for a new nano-displacement agent production device to solve the problems of low efficiency and easy adhesion in existing production devices during the modification of displacement agents. Utility Model Content

[0005] This invention provides a nano-oil displacement agent production device, which aims to solve the problems of low efficiency and easy adhesion in existing production devices when modifying oil displacement agents.

[0006] The present invention is implemented as follows:

[0007] A nano-displacement agent production apparatus, comprising:

[0008] The outer cylinder has a drive motor at its lower end;

[0009] The inner cylinder is fitted inside the outer cylinder, with a discharge port on its surface and a feed port at the top.

[0010] The roller is fitted inside the inner cylinder. The upper surface is provided with a circulation port and the lower surface is provided with an extrusion port. Multiple extrusion teeth are provided on the outer wall of the roller.

[0011] Furthermore, the cross-section of the extrusion tooth is arc-shaped, forming an angle of 10°-30° with the vertical line.

[0012] Furthermore, the bottom end of the roller is provided with a conical base.

[0013] Furthermore, the output shaft of the drive motor is fixedly connected to the bottom of the conical base.

[0014] Furthermore, the extrusion teeth are located on one side of the extrusion port.

[0015] Furthermore, the upper end of the extrusion tooth is flush with the lower end of the circulation port.

[0016] Furthermore, the outer side of the extrusion teeth contacts the inner side of the inner cylinder.

[0017] The beneficial effects achieved by this utility model are:

[0018] The material is initially mixed by having multiple extrusion teeth. Under the action of gravity, the material flows into the lower end of the extrusion teeth through the discharge port. The material is squeezed by the extrusion teeth, which can more fully and finely assist in mixing the material, effectively improving the mixing speed and uniformity of the material, thereby improving the modification efficiency. Furthermore, the addition of scrapers can scrape the inner wall of the cavity, preventing the material from sticking to the inner wall of the cavity during mixing, thus avoiding uneven mixing at the edges, and also preventing material residue on the inner wall of the cavity.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] In this embodiment, by providing a circulation port and an extrusion port inside the drum, the nano-oil displacement agent can fully contact and react, thereby improving the production efficiency of the nano-oil displacement agent. At the same time, the nano-oil displacement agent can be uniformly dispersed in the crude oil, avoiding local over-concentration or over-dilute conditions, and ensuring the uniformity and stability of the oil displacement effect.

[0028] It also features extrusion teeth, which allow the nano-oil displacement agent to flow and be extruded vertically, reducing manual intervention and improving production efficiency and safety.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment of the invention, a nano-oil displacement agent production device 100 is provided, comprising:

[0031] The outer cylinder 110 has a drive motor at its lower end;

[0032] The inner cylinder 120 is fitted inside the outer cylinder 110, and has a discharge port 121 on its surface and a feed port at its upper end.

[0033] The roller 130 is fitted inside the inner cylinder 120. The upper surface is provided with a circulation port 131 and the lower surface is provided with an extrusion port 133. Multiple extrusion teeth 132 are provided on the outer wall of the roller 130.

[0034] In this embodiment, a nano-displacement agent production device 100 promotes crude oil production by changing the fluid properties inside the oil well. The nano-displacement agent refers to an oil displacement agent with a particle size at the nanometer level, which has higher permeability and better dispersibility, and can more effectively improve the extraction efficiency of the oil field.

[0035] In this embodiment, the oil displacement agent production device includes an outer cylinder 110, which is used to hold the oil displacement agent and fix the inner cylinder 120 and the roller 130. The outer cylinder 110 can be cylindrical in shape and made of stainless steel. A drive motor is provided at the lower end of the outer cylinder 110. The drive motor can be fixed to the lower end of the outer cylinder 110 by bolt connection. The drive motor is used to drive the roller 130 to rotate. The output shaft of the drive motor passes through the outer cylinder 110 and the inner cylinder 120 and is fixedly connected to the roller 130.

[0036] In this embodiment, the oil displacement agent production device further includes an inner cylinder 120, which is used to hold the oil displacement agent, so that the oil displacement agent tumbles inside the drum 130 and the inner cylinder 120, thereby achieving uniform stirring of the oil displacement agent. The inner cylinder 120 can be cylindrical in shape and made of stainless steel. The inner cylinder 120 and the outer cylinder 110 can be fixedly connected by an inlay method, with the inner cylinder 120 fitted inside the outer cylinder 110. The drive shaft passes through the inner cylinder 120 and is connected to the drum 130.

[0037] In another embodiment, the nano-displacement agent production device 100 further includes a roller 130, which is disposed inside the inner cylinder 120. The roller 130 and the inner cylinder 120 are fixedly connected by an inlay method. The roller 130 can rotate freely. At the same time, a circulation port 131 is provided on the upper surface of the roller 130. The shape of the circulation port 131 can be elongated or circular. The specific shape can be selected according to the actual viscosity and flow rate of the displacement agent.

[0038] The lower surface of the roller 130 is provided with an extrusion port 133, which is used for extruding and mixing the oil displacement agent. The shape of the extrusion port 133 can be elongated, circular, or rhomboid, and the specific shape can be selected according to actual needs. Multiple extrusion teeth 132 are provided on the outer wall of the roller 130. The shape of the extrusion teeth 132 can be arc-shaped or elongated, and the specific shape can be selected according to actual needs.

[0039] Based on the above structure, during installation, the drive motor is fixed at the lower end of the outer cylinder 110, and the output shaft of the drive motor passes through the outer cylinder 110 and the inner cylinder 120 in sequence. The inner cylinder 120 is fitted inside the outer cylinder 110, and the roller 130 is fitted inside the inner cylinder 120. The output shaft is fixedly connected to the roller 130. During the production of the oil displacement agent, the oil displacement agent is placed inside the roller 130, and the drive motor is driven. When the roller 130 rolls, the nano-agent is placed inside the roller 130. The mixed oil displacement agent is input into the space between the inner cylinder 120 and the roller 130 through the extrusion port 133. The mixed oil displacement agent is driven by the extrusion teeth 132 to move along the extrusion teeth 132 to the circulation port 131. The oil displacement agent circulates through the above process until it is evenly mixed. When the oil displacement agent is mixed, it is discharged through the discharge port 121 of the inner cylinder 120.

[0040] In this embodiment, by providing a circulation port 131 and an extrusion port 133 inside the drum 130, the nano-oil displacement agent can fully contact and react, thereby improving the production efficiency of the nano-oil displacement agent. At the same time, the nano-oil displacement agent can be evenly dispersed in the crude oil, avoiding local over-concentration or over-dilute conditions, and ensuring the uniformity and stability of the oil displacement effect.

[0041] The material is initially mixed by the presence of multiple extrusion teeth 132. Under the action of gravity, the material flows into the lower end of the extrusion teeth 132 through the discharge port 121. The material is extruded by the extrusion teeth 132, which can more fully and finely assist in the mixing of the material, effectively improving the mixing speed and uniformity of the material, thereby improving the modification efficiency. Furthermore, the scraper can be set to scrape the inner wall of the cavity, preventing the material from sticking to the inner wall of the cavity during mixing, thus preventing uneven mixing at the edges. It can also prevent material residue from remaining on the inner wall of the cavity. The extrusion teeth 132 enable the nano oil displacement agent to flow and be extruded vertically, reducing manual intervention and improving production efficiency and safety.

[0042] Example 2

[0043] See Figure 2 In this embodiment of the invention, the cross-section of the extrusion tooth 132 is arc-shaped, forming an angle of 10°-30° with the vertical line.

[0044] In this embodiment, the cross-section of the extrusion tooth 132 is arc-shaped, specifically crescent-shaped, semi-circular, or elliptical. The specific shape can be selected according to actual needs. The material of the extrusion tooth 132 can be plastic, such as polyethylene, or metal, such as alloy steel. The specific material can be selected according to actual needs.

[0045] In this embodiment, the extrusion tooth 132 forms an angle of 10°-30° with the vertical line. The specific angle can be 10°, 15°, 20°, 25°, or 30°, and the specific degree can be selected according to the actual needs.

[0046] In this embodiment, the arc shape of the extrusion tooth 132 reduces friction between the tooth and the workpiece, thereby reducing wear and energy consumption during processing. Secondly, the arc cross-section facilitates uniform stress distribution, improving the gear's strength and durability. Furthermore, the 10°-30° included angle design effectively reduces noise and vibration during gear operation. The angle can be adjusted according to the concentration of the nano-oil displacement agent, increasing the mixing degree of the agent and improving work efficiency.

[0047] Example 3

[0048] See Figure 1 and Figure 3 In this embodiment of the utility model, the bottom end of the roller 130 is provided with a conical base 140.

[0049] In this embodiment, a conical base 140 is provided at the bottom of the roller 130. After the nano oil displacement agent source liquid enters the roller 130 through the feed port, the nano oil displacement agent source liquid enters the space between the roller 130 and the inner cylinder 120 along the extrusion port 133 under the action of gravity. Then, under the action of the extrusion teeth 132, it enters the roller 130 through the circulation port 131 along the extrusion teeth 132.

[0050] The conical base 140 design makes the roller 130 more stable during operation, reducing the possibility of equipment shaking and wobbling, thus ensuring the smooth progress of the production process; at the same time, the nano oil displacement agent source liquid enters between the roller 130 and the inner cylinder 120 along the extrusion port 133 under the action of gravity, which can reduce production costs and improve production efficiency.

[0051] Example 4

[0052] See Figure 1 In this embodiment of the utility model, the output shaft of the drive motor is fixedly connected to the bottom of the conical base 140.

[0053] In this embodiment, the output shaft of the drive motor is fixedly connected to the bottom of the conical base 140. The conical base 140 can rotate by the drive of the output shaft of the drive motor, thereby driving the roller 130 to rotate.

[0054] After the output shaft is fixedly connected to the bottom of the conical base 140, it can better transmit power, reduce energy loss, and improve the working efficiency of the motor. Since the output shaft is fixedly connected to the bottom of the base, the installation process is simpler and faster, no additional support structure is required, it is easy to maintain, and parts can be quickly replaced or repaired.

[0055] Example 5

[0056] See Figure 1 and Figure 2 In this embodiment of the present invention, the extrusion teeth 132 are disposed on one side of the extrusion port 133.

[0057] In this embodiment, the extrusion teeth 132 are disposed on one side of the extrusion port 133. When the extrusion teeth 132 rotate, the nano oil displacement agent source liquid will flow along the extrusion teeth 132, thereby achieving the stirring effect.

[0058] By setting the extrusion teeth 132 on one side of the extrusion port 133, the working efficiency of the extrusion port 133 can be effectively improved, the extrusion process can be controlled more precisely, and the extrusion material can be uniformly passed through the extrusion port 133 and then extruded by the extrusion teeth 132. It can also effectively prevent the nano oil displacement agent source liquid from shifting or clogging during the extrusion process, ensuring that the extrusion port 133 always remains unobstructed.

[0059] Example 6

[0060] See Figure 2 In this embodiment of the utility model, the upper end of the extrusion tooth 132 is flush with the lower end of the circulation port 131.

[0061] In this embodiment, the upper end of the extrusion tooth 132 is flush with the lower end of the circulation port 131, so that the nano-oil displacement agent source liquid can be smoothly extruded by the extrusion tooth 132 and enter the drum 130 through the circulation port 131 for circulation and stirring. The reasonable structure can greatly increase the stirring efficiency and the uniformity of the oil displacement agent source liquid mixing.

[0062] Example 7

[0063] See Figure 1 and Figure 2 In this embodiment of the invention, the outer side of the extrusion tooth 132 contacts the inner side of the inner cylinder 120.

[0064] In this embodiment, the outer side of the extrusion tooth 132 contacts the inner side of the inner cylinder 120, which can reduce assembly errors and movement gaps, making the movement of the mechanical device more stable and precise. At the same time, it can also scrape off the nano-oil displacement agent source liquid adhering to the surface of the inner cylinder 120, increasing the uniformity of stirring.
