Nonionic flocculants are widely used in the treatment of industrial wastewater. They have good flocculation performance, but do you know how to control the stirring speed and time of nonionic floccula...
The nonionic flocculant used in industrial wastewater treatment is mainly nonionic polyacrylamide, which has the properties of high purity, good solubility and wide molecular weight distribution. This...
In recent years, the extraction of shale gas has developed rapidly, and the recovery efficiency can be improved through transforming the reservoir by hydraulic fracturing technology. A large amount of...
Whether used in slickwater fracturing or coiled tubing stimulation, friction reducer can increase the pumping water displacement and maintain a low treatment pressure at the same time. Generally speak...
With the large-scale development of shale gas reservoir, the fracturing in using slickwater system needs high efficiency friction reducer products, and the ideal friction reducer should have low frict...
With the deepening of the research, friction reducer products are becoming mature and have entered the stage of commercial application. Both the new pipeline design and the existing pipeline operation...
Friction loop is one of the core performance indicators of friction reducers. The excellent drag reduction performance can significantly reduce the friction along the process and the hydraulic horsepo...
