Description

Technical Field

[0001] The present invention relates to the technical field of fracturing flowback fluid detection, and particularly to a viscosity detection device for the reuse of fracturing flowback fluid. Background Technique

[0002] The performance of fracturing fluid plays a crucial role in increasing oil production and reserves in oilfields. Through a viscosity detection device, the viscosity of the fracturing flowback fluid after treatment can be accurately measured to ensure that its reuse will not affect the overall performance of the fracturing fluid. This helps to maintain the fracturing effect and improve oil production efficiency. The viscosity detection device can monitor the viscosity change of the fracturing flowback fluid in real time. By adjusting the treatment process, the viscosity of the flowback fluid can reach the reuse standard, thus realizing the recycling of resources. This can not only reduce the injection volume of new liquid, lower the oil production cost, but also reduce environmental pollution. The main methods for detecting the viscosity of fracturing flowback fluid include the rotational viscometer method, on-line viscosity measurement technology, etc. When measuring the viscosity of a liquid by the rotational viscometer method, bubbles are likely to appear in the fracturing flowback fluid. The bubbles will reduce the contact area between the rotor and the liquid, resulting in a decrease in the resistance received by the rotor, slowing down the falling speed of the rotational viscometer rotor, and further causing the measured viscosity value to be on the low side, thus affecting the measurement result of the viscosity. Moreover, the viscosity of the fracturing flowback fluid is usually affected by temperature, resulting in errors in the measurement result.

[0003] The patent document with the publication number of CN221959969U discloses a viscosity detection device based on the reuse of fracturing flowback fluid, including a bottom plate, a second support frame, a cleaning component and a control component. A first support frame is installed on the bottom plate. A stirring mechanism is installed on the first support frame through an adjusting component. A mixing barrel for mixing the fracturing flowback fluid is installed on the first support frame. The stirring mechanism is connected inside the mixing barrel. A discharge pipe is provided at the lower end of the mixing barrel. The second support frame is installed at one end far from the first support frame. A detection mechanism is installed on the second support frame. Part of the structure of the cleaning component is installed on the stirring mechanism through an installation part. The control component is installed on the bottom plate; the viscosity of the fracturing flowback fluid can be detected, and the viscosity of the fracturing flowback fluid can be adjusted during processing to make the fracturing flowback fluid recycled, and the well site and the surrounding surface environment can be prevented from being polluted. However, the following problems still exist in the actual use of this patent:

[0004] Through the setting of the stirring mechanism, the viscosity detection device realizes the effect of adjusting the viscosity of the fracturing flowback fluid. However, since a large number of bubbles are easily generated in the fracturing flowback fluid during stirring, and the bubbles in the fracturing flowback fluid are likely to affect the accuracy of viscosity detection during detection, it is more inconvenient to adjust the viscosity of the fracturing flowback fluid. Moreover, when this viscosity detection device is in use, it is difficult to adjust the temperature of the fracturing flowback fluid, resulting in a relatively low accuracy of viscosity detection of the fracturing flowback fluid.

[0005] Therefore, we propose a viscosity detection device for the reuse of fracturing flowback fluid to facilitate the solution of the above-mentioned problems. Summary of the Invention

By arranging the compression spring 404 on one side of the lifting ring 405, when the sliding block 414 is separated from the guiding block 416, the lifting ring 405 can be quickly reset, so that vibrations are formed between the discharge box 407 and the liquid storage tank 310, achieving the promotion of the discharge of bubbles in the fracturing flowback fluid in the discharge box 407 and the liquid storage tank 310, thereby facilitating the reduction of the influence of bubbles in the fracturing flowback fluid on the accuracy of viscosity detection.

And the rotating shaft 415 and the sleeve 427 are arranged on one side of the liquid storage tank 310 close to the viscosity detection device 1.

The two ends of the return spring 426 are respectively fixedly connected to one side of the fixing plate 423 and one side of the telescopic plate 424. Through the movement of the piston 420 in the sleeve 427, when the discharge box 407 rises and the piston 420 contracts into the sleeve 427, the air in the discharge port 401 can be discharged, and when the discharge box 407 descends, the piston 420 is reset, achieving the effect of evacuating the discharge port 401, so as to further enhance the effect of discharging bubbles in the fracturing flowback fluid and reduce the influence of bubbles in the fracturing flowback fluid on the accuracy of viscosity detection.

[0048] The viscosity detection device 1 is slidably connected to one side of the inner wall of the heat insulation box 301 away from the liquid storage tank 310. The control panel 2 is fixedly installed on one side of the outer wall of the heat insulation box 301. There is a moving component 6 at the lower end inside the heat insulation box 301. The moving component 6 includes a moving seat 601. A detection seat 602 is installed on the top surface of the moving seat 601. The discharge box 407 is slidably connected to the inner wall of the liquid storage tank 310. The bottom of the discharge box 407 is inserted into the middle of the detection seat 602 through an anti-slip seat 410. By setting the detection seat 602, it is convenient for the discharge box 407 to be installed in the middle of the detection seat 602 through the anti-slip seat 410, making the placement of the discharge box 407 more stable.

[0049] Working principle: As Figures 1 - 11As shown in the figure, when using this device, first, inject the fracturing flowback fluid into the liquid storage tank 310 through the feeding port 303 and the liquid inlet 305, and turn on the power supply of the heater 307. The heater 307 at the bottom of the connecting shaft 306 on one side of the heat insulation box 301 heats the fracturing flowback fluid. At the same time, turn on the power supply of the motor 5, and the motor 5 at the upper end of the power frame 302 drives the rotating shaft 415 to rotate. Thus, the rotating shaft 415 drives the driving gear 428 to rotate, and the driving gear 428 drives the transmission gear 304 to rotate. As a result, the transmission gear 304 drives the inner scraper 308 and the outer scraper 309, and the inner scraper 308 scrapes the fracturing flowback fluid outside the heater 307, and the outer scraper 309 scrapes the inner wall of the liquid storage tank 310, realizing the heating and mixing of the fracturing flowback fluid.

[0050] Secondly, insert the upper end of the discharge box 407 into the middle of the discharge port 401, so that the lifting ring 405 slides upward on the sliding rod 403 inside the lifting groove 402, and the upper end of the discharge box 407 is threadedly connected with the internal thread 406 in the middle of the lifting ring 405 through the external thread 408. Subsequently, insert the discharge box 407 into the limit groove 412 at one end of the connecting plate 411, and make the limit ring 409 fit with the top surface of the connecting plate 411. By controlling the opening and closing valve 311, the fracturing flowback fluid falls into the discharge box 407.

[0051] Then, control the rotation of the rotating shaft 415 again, so that the rotating shaft 415 drives the guide block 416 to rotate. Thus, the guide block 416 pushes the sliding block 414 in the circular groove 413, and the sliding block 414 drives the connecting plate 411 to rise. As a result, the connecting plate 411 drives the discharge box 407 and the lifting ring 405 to rise outside the sliding rod 403 through the limit ring 409. At this time, the compression spring 404 contracts. At the same time, the rotating shaft 415 drives the eccentric wheel 417 to rotate. At this time, the eccentric wheel 417 pushes the telescopic rod 419 to slide in the sleeve 427 through the C-shaped frame 418, and the air pressure generated between the discharge port 401 and the discharge box 407 pushes the sealing plug 425 to separate from the exhaust port 421, and the telescopic plate 424 slides on the fixed rod 422 on one side of the fixed plate 423.

[0052] When the sliding block 414 separates from the guide block 416, the compression spring 404 pushes the lifting ring 405 to descend again. At the same time, the eccentric wheel 417 pulls the telescopic rod 419 to slide in the sleeve 427 through the C-shaped frame 418, and the return spring 426 pushes the sealing plug 425 to reset. Subsequently, the piston 420 slides outward of the sleeve 427, and the discharge box 407 descends, realizing the extraction of the gas in the discharge port 401 and the discharge box 407, and realizing the extraction of the bubbles in the fracturing flowback fluid.

[0053] Finally, take out the discharge box 407, place the discharge box 407 in the detection seat 602 through the anti-slip seat 410, and move the moving seat 601 so that the discharge box 407 falls below the viscosity detection device 1. Control the viscosity detection device 1 to descend through the control panel 2, and realize the test of the viscosity of the fracturing flowback fluid.
