This article uses three kinds of viscometry method, including a point method in the national standard 12891.5, dilution method in industry standard SY/T5862-2009 and China petroleum natural gas group company standard Q/SY QL 0122-2008, to determine polyacrylamide molecular weight of more than 100, 000 and ensures its distribution. The results show that the difference of value is less than 1%, and the difference of distribution is less than 2% by using three determination methods to determine molecular weight of partial hydrolysis polyacrylamide. In addition, it has explored and summarized through the experiment and relevant literature and found that the influence factors of relative molecular weight about the viscosity measurement of polyacrylamide include many factors such as objective condition, viscometer, solution concentration and temperature control precision of the constant temperature trough.
