Factors Influencing HPAM Solution Viscosity Prepared by Produced Water Using Orthogonal Method
The effect of temperature and metal ion components on the viscosity of HPAM solution was studied by means of orthogonal method. Five factors and 4 levels were considered for the orthogonal design. The five factors included temperature, contents of Na+, Mg2+, Ca2+ and S2-, and the four levels mainly considered the level of produced water components in main oilfields in China. The experiment results show that temperature is the most important factor to control HPAM solution viscosity prepared by produced water. The effect of ions was in order of Na+>S2->Mg2+>Ca2+. The mechanism of each factor influencing viscosity was also discussed. Based on the actual condition of Nanyang oilfield, the desulfurization was used to improve the solution viscosity, and satisfactory result was obtained.
