Abstract
Alkaline/surfactant/polymer (ASP) flooding has been applied to oil extraction in Daqing oilfield in several years. It is a great technology to improve oil recovery after polymer flooding. However, the agent would produce lots of fluid compositions, including a lot of polymer, alkaline and surfactant chemicals, which can improve the output of crude oil but increase the difficulty to disposal, such as fluid emulsion serious, smaller oil bead particle size and higher sewage viscosity and so on. An efficient demulsifier is urgent researched. In the paper, some development and application of common emulsifiers were introduced, including Quaternary ammonium salt of demulsifier, Amine polyether demulsifiercess and Water-oil separation agent Drows-1. It is significance to research the efficient green environmental protection demulsifier, which will decrease environmental pollution and increase sewage treatment efficiency in future.
