Polyacrylamide (S-PAM), as a new type of oil displacement agent in oilfield,
integrates the advantages of both polymer and surfactant. The oil displacement
experiments using S-PAM in multi-blocks reveal that in-use S-PAMs differ
greatly from ordinary polymers and the physical properties remain unclear. This
is unfavorable to production application and occupational health and safety. This
research compared the physical properties of S-PAMs selected from two producing
area, including specific gravity, particle size and viscosity. The compared
results showed that specific gravity of Lianhua S-PAM was smaller than Haibo
S-PAM; Lianhua S-PAM and Haibo S-PAM accounted for the 93.8% and 80.1% of the
total amount via the particles with 40 mesh and 60 mesh; the viscosity of
Lianhua S-PAM was higher than that of Haibo S-PAM in two S-PAM solutions with
