Good water solubility: After the operation is completed, it can be easily dissolved by means of water injection or other methods to achieve the removal of the plug, leaving no residues in the formation

Rapid plugging: It can quickly form a tight plugging structure, effectively preventing the passage of fluids, and showing a remarkable temporary plugging effect

High selectivity: It conducts targeted plugging of formations with specific pore and fracture sizes, precisely acting on the parts that need temporary plugging

Little formation damage: Its components are environmentally friendly and it has stable chemical properties, minimizing the impact on the permeability of the reservoir

In petroleum extraction: During well drilling and completion, it plugs the lost circulation zones to prevent the loss of drilling fluid and protect the reservoir. In workover and fracturing operations, it temporarily plugs specific areas, facilitating subsequent operations

In water conservancy projects: It is used for seepage prevention and plugging in facilities such as dams and sluices. It swells upon contact with water to form a plugging structure, preventing water seepage

In construction: During underground construction, it deals with the water gushing layers to ensure the safety and smooth progress of the construction
