Chemical Gel Plugging Agent
FC-S73S plugging agent consists of composite plugging particles compounded with natural biopolymer materials. When added into isolation fluid systems, the blended components form compact sealing layers against borehole fractures, effectively stopping slurry circulation loss during well cementing and drilling operations.
This product is suitable for plugging cracks and pores below 500μm.
