Study on the Composite Viscosity Reducers for Extra-Viscous Crude Oils

The optimum condition of composite viscosity reducer was oabtined here. It indicates that coordination and synergic function indwell the composite viscosity reducer for optimum composite viscosity reducer's viscosity reducing property being more effective than solo one's in it and inferior composite viscosity reducer's viscosity reducing property being not as good as some solo one's in it by experiment.It can make the viscosity reducing property of composite viscosity reducer more effective to explore the law in the composite viscosity reducer.
