Research and application of treatment technology of oilfield sump oil;

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.

According to preparing polymer solution by oilfield produced water, the effect of ions and salinity on polymer solution viscosity was explored and discussed.
