[0002] Emulsion-type fracturing fluid drag reducer is a special chemical additive used in oil and gas field fracturing operations. Emulsion-type fracturing fluid drag reducer usually exists in the form of an emulsion, that is, the oily additive in the aqueous liquid is suspended in water to form an emulsion. This form of drag reducer is conducive to uniform dispersion in the aqueous liquid, improving the effect of the drag reducer and ensuring that it can play a better role in the fracturing process. Emulsion-type fracturing fluid drag reducer needs to form a uniform emulsion in water. Mixing equipment can ensure that the additive is fully mixed with water, prevent the additive from agglomerating or unevenly dispersing, so as to achieve the best drag reduction effect.

However, this method cannot heat the materials during mixing. In a low temperature environment, some materials will become viscous and the viscosity will increase, which will reduce the mixing efficiency and make the mixing process more difficult and time-consuming. The lack of heating function may limit the processing capacity of these materials and affect production efficiency. The high viscosity of the materials will lead to uneven mixing, and some components are difficult to completely dissolve or evenly disperse, thereby affecting the quality and stability of the product.
