Polymer relies on its special properties, which is an effective means to enhance oil recovery. But the composition of its produced liquid is very complex, especially emulsifying phenomenon severely constrains the process oil-water separation at a later stage. At present technical means of demulsification taken by both home and abroad oilfield mainly include physics, chemistry and other methods....

The article deals with the issues of improving quality highly watered well production fluid processing using chemical demulsifier reactants at crude oil facilities; analysis use Samotlor field has been made. presents results study effectiveness "Hercules 2202 grade A" and "SNPH-4460-2" demulsifiers in comparison indicators bottom water achieved presence used existing their optimal consumption d...
