Problems solved by technology

[0002] During the fracturing construction process, it is necessary to continuously mix the guar gum base fluid through the mixing truck to ensure the smooth progress of the construction. At present, manual sampling is generally used to detect the viscosity of the base fluid during the fluid mixing process. The viscosity detection method of the base fluid is in Sampling at the export of the mixed vehicle, and then checking the readings with a six-speed rotary viscometer, and judging whether it is necessary to adjust the addition ratio of the guar gum powder according to the testing results. This testing method requires more personnel, and sampling and testing are required. There is a time interval in the detection process, and there will be discontinuous detection of the viscosity of the base liquid, slow feedback of viscosity values, and failure to detect changes in viscosity in time; and when guar gum powder is added to the mixing vehicle, the guar gum powder is not evenly fed, When encountering liquid materials, it is easy to condense into agglomerates, which will lead to uneven viscosity of the prepared base fluid, which will affect the configuration of subsequent fracturing fluids and reduce the sand-carrying performance of fracturing fluids. Therefore, the present invention proposes a base fluid Viscosity automatic calibration device to reduce and avoid the occurrence of this situation
