【Abstract】 Through physical analysis of crude oil in Suizhong 36-1 Oilfield, initial selection is made on polymer viscosity reducing agent monomer accordantly and a series of viscosity reducing agents are synthesized, through result selection and research of all the synthesized viscosity reducing agents. The polymer viscosity reducing agent BST-RT and its formula with good viscosity reducing effect to Suizhong 36-1 Oilfield are determined. The effect of other factors on viscosity reducing efficiency and the effect of the application of the agent on crude oil process of the system are studied with the existence of the polymer viscosity reducing agent. The result indicates that BST-RP viscosity reducing agent has better integral result, of which no bad influence would be caused in oil production and late oil process.更多还原
