[0002] In the complex and critical industrial field of oil extraction, fracturing and acidizing products in oilfield additives play a crucial role, serving as indispensable materials for ensuring efficient production and enhancing oil and gas recovery rates. Among these, various emulsion polymers, as core components of the fracturing and acidizing product system, are used in extremely large quantities, reaching tens of thousands of tons annually. These emulsion polymers, with their unique properties such as excellent thickening, proppant carrying, and filtration loss reduction capabilities, can effectively form fractures of a certain width and conductivity during fracturing operations, allowing oil and gas to flow more smoothly into the wellbore. In acidizing operations, they help improve the rheological properties of the acid solution, enhancing the acidizing effect and thus significantly increasing oil well production.

[0037] 2. The integrated skid-mounted device for emulsion polymer storage and supply provided by this utility model features a storage tank wrapped with two electric heating cables.

Simultaneously, nano-aerogel is used to insulate the tank, preventing heat loss. Temperature sensors monitor the temperature of the emulsion polymer inside the tank and transmit the data to the control system. The control system then controls the electric heating cables based on the temperature parameters, initiating and stopping the heating to maintain a constant temperature for the emulsion polymer, thus reducing its viscosity and increasing its fluidity. This effectively solves the problem of high viscosity in low-temperature winter environments. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] like Figure 1 and Figure 2 As shown, an integrated emulsion polymer storage and supply skid-mounted device includes a skid 1 and a storage tank 2; the skid 1 is the installation base of the entire equipment and is welded into an integral frame using profiles.

One end of the circulating pipeline 7 is placed at the inner bottom of the liquid storage tank 2, and the other end penetrates the liquid storage tank 2 from top to bottom and is connected to the feeding component 3;

[0049] Outside the liquid storage tank 2, there is a heating module. At the bottom of the liquid storage tank 2, there are multiple temperature detection sensors 8. The heating module and the temperature detection sensors 8 are both connected to the control system 5 and the power supply system 6; the control system 5 receives the temperature data of the temperature detection sensors 8 and controls the heating module to heat the liquid storage tank 2.

[0051] As Figure 3 and Figure 4 shown in the figure, the feeding component 3 includes two feeding pipes 31; on the feeding pipes 31, there are successively a feeding quick connector 32, a feeding valve 33, a filter 34, and a feeding pump 35; by setting the filter 34, it is used to filter the larger flocs in the emulsion; in order to make the emulsion disperse the materials at the bottom of the liquid storage tank 2 after entering the liquid storage tank 2, the end of the feeding pipe 31 far from the feeding quick connector 32 extends into the liquid storage tank 2 and is provided with an elbow 36; the opening of the elbow 36 faces downward; the feeding valve 33 and the feeding pump 35 are connected to the control system 5 and the power supply system 6; the power supply system 6 supplies power to the feeding valve 33 and the feeding pump 35, and the control system 5 can control the opening or closing of the feeding valve 33 and the feeding pump 35.

[0056] The power supply system 6 supplies power to the circulation valve 73, and the control system 5 can control the opening and closing of the circulation valve 73.

[0057] When the material in the storage tank 2 is stationary, the feed valve 33 can be closed and the circulation valve 73 can be opened. The feed pump 35 will draw the material from the bottom of the storage tank 2 through the circulation pipe 71 and return it to the storage tank 2 through the feed pipe 31 and the bend pipe 36, so that the material in the storage tank 2 will not separate.
