Technical Field

[0001] The utility model relates to the technical field of suspension preparation, in particular to a stirring device for preparing oil-based fracturing drag reducer suspension. Background Art

[0002] Drag reducers play a vital role in oil production, especially in fracturing operations. They can significantly reduce the resistance of fluids flowing through pipelines, thereby improving pumping efficiency and reducing energy consumption. The use of drag reducers can significantly increase the success rate of fracturing operations and reduce construction costs. The preparation of oil-based fracturing drag reducer suspensions requires ensuring that the drag reducer particles are evenly dispersed in the oil-based medium and remain stable over the long term. Therefore, it is necessary to design a stirring device for the preparation of oil-based fracturing drag reducer suspensions.

[0003] The traditional stirring device for preparing oil-based fracturing drag reducer suspension directly discharges the suspension after preparation, which is inconvenient to treat the suspension, resulting in impurities and debris remaining in the suspension, affecting the pumping efficiency during use. Therefore, it is necessary to design a stirring device for preparing oil-based fracturing drag reducer suspension that can facilitate filtering of the suspension. Utility Model Content
