Recent advances of modified polyacrylamide in drilling technology

Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

Soil¨Crock mixtures are commonly encountered in the construction of bored piles. Conventional bentonite support fluids have disadvantages, such as more significant environmental impacts, more complex mixing, bigger site footprint, weaker foundation performance, and overall low economies. The present study conducted a comprehensive investigation of partially hydrolyzed polyacrylamide (PHPA
