摘要

Polyaspartic acid modified by sulfonic acid group (PASP/ASA) was synthesized and characterized, and then its comprehensive scale inhibition performance was tested in the laboratory simulated environment as an oilfield scale inhibitor. By statically experiment the performance of polyaspartic acid/ aminomethanesulfonic acid in inhibiting CaSO4 and CaCO3 scale under different synthesis condition, results present that the maximum scale inhibition efficiency of the prepared PASP/ ASA for CaSO4 and CaCO3 scale is 100% and 83.36% at the dosage of 2.5 mgL~(-1) and 10 mgL~(-1), respectively.
