Stability Evaluation of Surfactant-Grafted Polyacrylamide Used in Oilfields by Evolution of Ammonia ()
ABSTRACT
Surfactant-grafted Polyacrylamide
(S-PAM) serves as a novel oil displacement agent in oilfield. The analysis on composition
of S-PAM shows that due to its instability the harmful ammonia gas may be generated
during the operation of S-PAM or high temperature. In this paper, stability of S-PAM
was studied by measuring the ammonia release from solid and aqueous S-PAM at different
temperatures. The results showed that ammonia release of the solid S-PAM was increased
with raising temperature. The ammonia release from S-PAM produced by Haibo Company
is more than one from Lianhua in the solid state. The ammonia emissions from Lianhua
S-PAM are slightly higher than Haibo one in the solutions prepared by both clean
water and oilfield water.
