摘　　要：渤海油田稠油储量占比大且具有粘度高、凝固点低、密度大、原油物性差异大等特点,本文针对渤海目标稠油油田开展原油高压物性分析,在室内筛选出了一种适合海上稠油油田的高效水溶性降粘剂SJJNJ-2,并对该体系的降粘性能进行评价,结合目标稠油油田深入分析了温度、体系加量对其降粘效果的影响,实验结果表明:高效水溶性降粘剂SJJNJ-2对渤海目标稠油具有明显的降粘效果,可在50℃、质量浓度0.5%的加量条件下实现降粘率95%以上。Bohai oilfield heavy oil reserves accounted for big and has high viscosity and low freezing point,density,and the characteristics of large difference of physical property of crude oil,the bohai sea target of heavy oil fields,the author of this paper carried out analysis of high pressure physical properties of crude oil,indoors,a kind of suitable for offshore heavy oil field of efficient water soluble viscosity agent SJJNJ-2,and viscosity of the system can evaluate,in-depth analysis of the temperature,combining with the target of heavy oil oilfield system,and the effects of adding amount on the viscosity,the experimental results show that:SJJNJ-2,a highly efficient water-soluble viscosity reducer,has obvious viscosity reduction effect on target heavy oil in Bohai Sea,and can achieve viscosity reduction of more than 95%at 50℃and mass concentration of 0.5%.
