Polyacrylamide For Edge-water Encroachment Use

Polyacrylamide for edge-water encroachment use

[ Properties ]
Polyacrylamide for edge-water encroachment use is produced specially for polymer ( EOR ) by new technique. Maximum molecular weight : 24 million. Medium hydrolysis, high viscosity and good solubility.
[ Usage ]
PAM As Oil-displacing Agent
When the oil field is exploited in the petroleum tertiary recovery, if the single injection drive is applied, its fluidity is higher than the crude move, as a result, it lowers the spread efficiency and increases the water consumption, the water content of the crude oil will be increased. In addition, the oil field is positive rhythm deposition, in which the upper part of the oil layer is rougher than the lower part and the permeability in the lower part is higher than the upper part's. When the single water drive is applied, the oil is driven along the bottom, and large quantity of the crude oil is still retained in the upper part. If PAM is applied, it can improve the spread efficiency, and lower the water content in the crude oil displaced and raise the productive output. Some hydrolysis PAM made in our company is conformed with the requirements in the petroleum tertiary recovery. It can be used according to the features on the oil fields (stratum, mineralization and the viscosity of the polymer solution filled).
