INFLUENCE WATER MINERALIZATION ON THE RHEOLOGICAL PROPERTIES POLYMER
The impact of salinity water (12 mg/l and 20 g/l) on the dynamic viscosity of the anionic polyacrylamide was revealed. Tests wereconducted on the rheometer HAAKE MARS III. It is shown that the dynamic viscosity of polyacrylamide with a small quantity of anionic charge (23.2%) and low molecular weight (12.7 million) increased with growing up salt content in the water solution. It is revealed, that the oil well temperature has a great effect on the rheological properties of the anionic polymer of acrylamide. The influence of polymer molecular weight and value of its anionic charge on the dynamic viscosity of polyacrylamide was studied.
