The analysis and research of new fracturing fluid dynamic mixer

Fracturing operation is an important link in the process of petroleum and natural gas extraction, and the preparation of fracturing fluid is the key factor to the fracturing operation. In order to solve the problems of insufficient amount of rubber guanidine powder inhalation and a lot of powder package, a new type of fracturing fluid dynamic mixer is designed. The principle of annular jet and the discrete action of powder are applied in the design process. The main advantages of new mixer are large powder intake, uniform mixing and high inhalation efficiency. Through the combination of numerical simulation and experimental verification, the new fracturing fluid dynamic mixer is analyzed, the key structure size of the mixer is optimized, and its performance parameters are optimized. After optimization, the negative pressure value of new fracturing fluid dynamic mixer can research 0.0872MPa, and it can well meet the requirements of inhalation performance.
