| 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 in described acrylamide based copolymer on the basis of the total mole number of construction unit, the content of described construction unit A is 5 95 moles of %, the content of described construction unit B is 2.5 90 moles of %, and the content of described construction unit C is 0.5 90 moles of %；The viscosity average molecular weigh of described acrylamide based copolymer is 2,000,000 1,500 ten thousand.The acrylamide based copolymer drag reducing efficiency that the present invention provides is high, heat-resisting and salt tolerance high shear performance high, anti-is good, good water solubility and clay stabilizer (alcohol) have good compatibility, viscosity average molecular weigh is low and little to the nocuity on stratum. |
