This invention provides a multifunctional electrolyte preparation tank, comprising a transparent tank body. Inside the tank body, a temperature measuring component and a specific gravity measuring component are detachably installed. The temperature measuring component includes a first mounting box and a thermometer, with the thermometer installed inside the first mounting box. The specific gravity measuring component includes a second mounting box and a hydrometer, with the hydrometer installed inside the second mounting box. Both the first and second mounting boxes are inserted into the inner wall of the preparation tank body. By stably installing the thermometer and hydrometer in the first and second mounting boxes respectively, the temperature can be directly observed without removing the thermometer, avoiding inaccurate readings due to ambient temperature. Simultaneously, the hydrometer is confined within the second mounting box and does not float, solving the problem of difficult readings caused by the floating and swaying of traditional hydrometers. This achieves stable, accurate, and real-time monitoring of temperature and specific gravity during electrolyte preparation.

The invention relates to a method for measuring the sand-carrying capacity of emulsion fracturing fluid. The method comprises the following steps: measuring the apparent density rho of the emulsion fracturing fluid by using a buoyancy type densimeter; measuring the actual density rho 0 of the emulsion fracturing fluid by using a weighing densimeter; the difference value between the apparent density rho of the emulsion fracturing fluid and the actual density rho 0 of the emulsion fracturing fluid is used for representing the sand-carrying capacity of the emulsion fracturing fluid, and the larger the difference value is, the larger the sand-carrying capacity of the emulsion fracturing fluid is. After the measuring method is put into use, the measurement is simple and convenient, the result can be quickly obtained, and the measuring efficiency of the emulsion fracturing fluid on-site measurement of the sand-carrying capacity is improved. And on-site temporary adjustment is facilitated, the fracturing construction stopping time is shortened, and the fracturing construction efficiency is improved.
