Description

Technical Field

[0001] The invention relates to the technical field of fracturing flowback fluid detection, in particular to a viscosity detection device for fracturing flowback fluid reuse. Background Art

[0002] The performance of fracturing fluid plays a vital role in increasing the production and reserves of oil fields. Through the viscosity detection device, the viscosity of the fracturing return fluid after treatment can be accurately measured to ensure that its reuse will not affect the overall performance of the fracturing fluid, which helps to maintain the fracturing effect and improve oil production efficiency. The viscosity detection device can monitor the viscosity change of the fracturing return fluid in real time. By adjusting the treatment process, the viscosity of the return fluid can reach the reuse standard, thereby realizing the recycling of resources, which can not only reduce the injection amount of new liquid and reduce the cost of oil production, but also reduce pollution to the environment. The viscosity detection methods of fracturing return fluid mainly include rotational viscometer method, online viscosity measurement technology, etc. When the rotational viscometer method is used to measure the viscosity of the liquid, bubbles are prone to appear in the fracturing return fluid, and the bubbles will reduce the contact area between the rotor and the liquid, resulting in a decrease in the resistance of the rotor, slowing down the descending speed of the rotor of the rotational viscometer, and then making the measured viscosity value low, thereby affecting the viscosity measurement result, and the viscosity of the fracturing return fluid is usually affected by temperature, resulting in errors in the measurement result.

However, since a large number of bubbles are easily generated in the fracturing return fluid during stirring, and the bubbles in the fracturing return fluid are easy to affect the accuracy of viscosity detection during detection, it is inconvenient to adjust the viscosity of the fracturing return fluid. In addition, when the viscosity detection device is in use, it is difficult to adjust the temperature of the fracturing return fluid, resulting in low accuracy in viscosity detection of the fracturing return fluid.

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, so that the placement of the discharge box 407 is more stable.

[0031] Working principle: Figure 1-Figure 11As shown, when using the device, first, the fracturing return fluid is injected into the liquid storage tank 310 through the feed port 303 and the liquid inlet 305, and the power of the heater 307 is turned on, so that the heater 307 at the bottom of the connecting shaft 306 on one side of the insulation box 301 heats the fracturing return fluid, and at the same time, the power of the motor 5 is turned on, so that the motor 5 at the upper end of the power frame 302 drives the rotating shaft 415 to rotate, so that the rotating shaft 415 drives the driving gear 428 to rotate, and the driving gear 428 drives the transmission gear 304 to rotate, so that the transmission gear 304 drives the inner scraper 308 and the outer scraper 309, so that the inner scraper 308 scrapes the fracturing return fluid on the outside of the heater 307, and the outer scraper 309 scrapes the inner wall of the liquid storage tank 310, so as to achieve heating and mixing of the fracturing return fluid.
