| titleOfInvention | A kind of acrylamide based copolymer and its preparation method and application |
| abstract | The invention discloses a kind of acrylamide based copolymer and its preparation method and application. Described acrylamide based copolymer contains construction unit A, construction unit B and construction unit C, wherein, described construction unit A is the construction unit shown in formula (1), and described construction unit B is the construction unit shown in formula (2), and described construction unit C is the construction unit shown in formula (3); And taking the total mole number of construction unit in described acrylamide based copolymer as benchmark, the content of described construction unit A is 5-95 % by mole, and the content of described construction unit B is 2.5-90 % by mole, and the content of described construction unit C is 0.5-90 % by mole; The viscosity average molecular weigh of described acrylamide based copolymer is 2,000,000-1,500 ten thousand. Acrylamide based copolymer drag reducing efficiency provided by the invention is high, heat-resisting and high, the anti-high shear performance of salt tolerance is good, good water solubility, have good compatibility, viscosity average molecular weigh low and little to the nocuity on stratum with clay stabilizer (alcohol). |
