Nd G, In C · Shiyou yu tianranqi huagong · 2000
Drilling fluid additives preperation methods by graft copolymerization were introduced. The drilling fluid additives were synthesised by graft copolymerization using many kinds of monomers and natural macromolecular materials including cellulose,starch,lignin,humic acid and quebracho. This paper reviewed briefly their research and application.
