Abstract
Description
Technical Field
[0001] This utility model relates to the field of oilfield tracer injection technology, specifically a tracer preparation device. Background Technology
[0002] Fracturing tracer monitoring technology is widely used in oilfields. During the fracturing process, a tracer is added to the fracturing fluid to analyze the fracturing effect and determine if there are any engineering problems during the operation. The tracer is prepared by stirring and heating a tracer mother liquor with water, and then injected into the fracturing fluid storage tank.
[0003] However, current tracer equipment often suffers from several problems. For example, after the tracer is prepared, prolonged static transport can cause it to precipitate at the bottom, leading to a decrease in tracer concentration. This decrease in concentration may further affect the accuracy of detection. Furthermore, the preparation vessel may shift or even tip over during transport, further exacerbating the instability and inconvenience of use. Utility Model Content

Simultaneously, when the transport device accelerates or decelerates, the preparation vessel may shift due to horizontal forces, causing the first and second sliding blocks to slide relative to each other. Under the action of the relative inclined surfaces of the first and second sliding blocks, the support is subjected to inward compressive force, further preventing displacement of the preparation vessel. Through the design of the sliding sleeve, rotating plate, and rotating ring, the power provided by the start and brake of the transport mechanism drives the sliding sleeve and rotating plate to move the rotating ring and its internal rotating frame, stirring the liquid inside the preparation vessel. This dynamic stirring design effectively prevents the tracer inside the preparation vessel from remaining static for extended periods, reducing the formation of sediment and suspended matter, thereby maintaining the tracer's uniformity and avoiding changes in detection accuracy due to concentration reduction.

[0028] Please see Figure 1-7 ,
[0029] A tracer preparation apparatus includes a transport device 1 and a frame 2. The frame 2 is mounted on the back of the transport device 1. A fixed frame 3 is provided inside the frame 2. Fixed sleeves 7 are provided on the top and bottom of the front and rear sides of the fixed frame 3. Guide posts 8 are provided inside the fixed sleeves 7 for connecting with the fixed frame 3. The guide posts 8 are used to install the fixed top sleeves on the fixed frame 3 by bolts 6. Rotating sleeves 9 are installed on the fixed sleeves 7. A screw 10 is connected to the guide posts 8. Both the fixed sleeves 7 and the rotating sleeves 9 are provided with threaded holes that mate with the screw 10. The other end of the screw 10 is connected to a first sliding block 11. The first sliding block 11 mates with a second sliding block 12. A base 14 is provided inside the fixed frame 3. A preparation vessel 5 is provided on the top of the base 14. A rotating ring 13 is provided on the preparation vessel 5. The rotating ring 13 mates with the moving devices 4 at both ends of the top of the fixed frame 3.
[0030] In this example, the base 14 is located in the middle of the fixed frame 3, and the top of the base 14 is provided with a through hole that matches the bottom of the preparation vessel 5. The fixed frame 3 is provided with a through hole that matches the guide post 8 and the bolt 6. The rotating ring 13 is rotatably connected to the preparation vessel 5. The rotating ring 13 is provided with a rotating frame 15 inside, and the outer ring of the rotating ring 13 is provided with helical teeth.
[0031] It should be noted that the top of the base 14 is specially provided with a through hole that matches the bottom of the preparation vessel 5. This design not only enables the preparation vessel 5 to be accurately positioned and stably installed on the base 14, but also ensures the stability of the preparation vessel 5 during rotation and stirring through the cooperation of the through hole.
[0032] In this example, the guide post 8 is provided with a limiting block that cooperates with the inside of the fixed sleeve 7, and the outer ring of the guide post 8 is provided with an extension key. The end of the guide post 8 away from the fixed sleeve 7 is provided with a threaded hole that cooperates with the bolt 6. The rotating sleeve 9 is located at the end of the fixed sleeve 7 away from the fixed frame 3 and is rotatably connected to the fixed sleeve 7.
[0033] It should be noted that the presence of the limiting block not only achieves precise positioning and stable connection between the guide column 8 and the fixed sleeve 7, but also prevents the guide column 8 from excessively deviating or shaking during movement through its limiting function, thus ensuring the stability and reliability of the entire mechanism.
[0034] In this example, the part of the screw 10 that mates with the guide post 8 is provided with a through hole and a keyway. The end of the bolt 6 away from the guide post 8 is fixedly installed at the middle position on the back of the first sliding block 11. Both the first sliding block 11 and the second sliding block 12 are triangular in shape, and the part of the first sliding block 11 that mates with the second sliding block 12 is provided with a slider and a groove. The end face of the second sliding block 12 away from the first sliding block 11 is provided with an anti-slip pad.
[0035] It should be noted that the design of the bolt 6 installation position not only ensures a stable connection between the bolt 6 and the first sliding block 11, but also further enhances the connection strength between the screw 10 and the guide post 8 through the fastening effect of the bolt 6.
[0036] In this example, the motion device 4 consists of a sliding sleeve 401, a configuration groove 402, a counterweight 403, a fixed block 404, a rotating plate 405, and a spring 406. The configuration groove 402 is fixedly installed at the bottom of the sliding sleeve 401, and the counterweight 403 is located inside the configuration groove 402. The fixed block 404 is fixedly installed at the top of the sliding sleeve 401. The rotating plate 405 is fixedly installed at one end of the fixed block 404 near the preparation vessel 5. One end of the spring 406 is connected to the fixed block 404, and the other end is connected to the rotating plate 405.
[0037] It should be noted that the presence of counterweight 403 not only increases the overall weight of the motion device 4 and improves its stability during rotation, but also allows for precise control of the speed of the motion device 4 and the stirring force of the rotating frame 15 by adjusting the number and position of counterweight 403.
[0038] In this example, the sliding sleeve 401 has a through hole that mates with the fixed frame 3. The fixed block 404 is installed at the middle position on the top of the sliding block. The rotating plate 405 is rotatably connected to the fixed block 404. The spring 406 is disposed between the fixed block 404 and the rotating plate 405. The rotating plate 405 mates with the outer ring and helical teeth of the rotating ring 13.
[0039] It should be noted that the through hole design not only ensures the smooth sliding of the sliding sleeve 401 on the fixed frame 3, but also achieves precise positioning and stable support for the entire motion system through the precise fit of the through hole. The fixed block 404, as the support and connecting component of the rotating plate 405 and the spring 406, undertakes the important task of transmitting force and torque.
[0040] In summary: When using this device, the liquid is first injected into the preparation vessel 5. Then, the bolt 6 is inserted into the guide post 8, and the rotating sleeve 9 is installed on the fixed sleeve 7 along with the guide post 8. Next, the fixed sleeve 7 is installed on the fixed frame 3 using the bolt 6. Rotating the rotating sleeve 9 drives the screw 10, causing the first sliding block 11 and the second sliding block 12 to press against the inner side of the frame 2, thus securely installing the fixed frame 3 inside the frame 2. During transportation, when the transport device 1 starts or brakes, the first sliding block 11 and the second sliding block 12 slide relative to each other along the inclined surface of the mating joint, generating an inward squeezing force, thereby enhancing the stability of the fixed frame 3 and effectively preventing displacement of the preparation vessel 5. Simultaneously, the sliding sleeve 401 slides on the top of the fixed frame 3 and, through the rotating plate 405, drives the rotating ring 13 and its internal rotating frame 15 to dynamically stir the liquid inside the preparation vessel 5. This design effectively prevents the tracer from remaining stationary in the preparation vessel 5 for extended periods, avoiding the formation of sediment or suspended matter, ensuring uniform tracer concentration, and thus guaranteeing the accuracy and reliability of the detection.
[0041] Beneficial effects:
