Preparation of an ASP system using high salinity water from oilfield sewage treated by electrodialysis;

It is difficult for the traditional physical and chemical process to dispose the oilfield sewage up to the discharge standard.

In view of the weaknesses of SY/T 5329-94 in determining oil content of oilfield sewage,a discussion is made on the basis for improvements in standard oil preparation,solvent for extraction,wave lengths for color comparison,and the drawing of typical curve.
