| Abstract: | Polymeric viscosity-reducer PT-1 is a copolymer of maleic anhydride with vinyl monomer and acrylamide and synthesized through an initiation polymerization reaction. Its synthesis is briefly described,its chemical structure is investigated by IR and thermal properties by DTA and TG analyses.The performance evaluation tests are conducted in three laboratory muds (a fresh water bentonite,a weighted fresh water bentonite,and a polymer muds)and multisulfopolymer drilling muds from two wells.In all cases tested PT-1 is better than or similar to a complex ionic mud additive,XY-27,and sulfonated tannin,SMT.Its thermal stability,salt and calcium- tolerence are satisfactory,too. |
