Analysis on Toxic and Hazardous Substances of Polymer Surfactants Used in Oilfields

Abstract

Polymer surfactant, which combines the advantages of polymer and surfactant, is a new type of oil displacement agents in oilfield.Meanwhile, the hazardous composition of the polymer surfactant is unknown.In order to clarify its potential impacts on the operator health during production,the hazardous composition and toxicity in the two solutions ,which polymer surfactants prepared by using fresh water and waste water were investigated.And the existence of inorganic and organic pollutants in the solution were also studied.The results were shown that determination of inorganic phosphorus and arsenic exceeded the standard limits.The polymer surfactant powder and solution extraction products were analyzed, it can be concluded basicly that there is no organic pollutants, or it can be ignorable.
