摘　　要：本文针对辽河兴隆台油田，研究了原油与ＮａＯＨ，Ｎａ２ＣＯ３等碱液间的动界面张力，着重考察了碱、聚合物复合体系对油水间动界面张力的影响。结果表明，原油与碱水间的界面张力随时间的变化为一动态变化过程；聚合物的加入，使原油与碱水间的动界面张力降低；碱浓度越高，原油与碱水间的平衡动界面张力越稳定；生物聚合物对碱水驱动界面张力影响特别敏感（即更有利于降低动界面张力）In view of Xinglongtai oil field, Liaohe, this paper studies the dynamic IFT between crude oil and alkaline liquids, such as NaOH and NaCO 3 and particularly examines the effect of alkalipolymer system on the dynamic IFT between oil and water. The results show that the change of IFT between crude oil and alkaline wate with time is a dynamic one; The adding of polymer decreases the dynamic IFT between crude oil and alkaline water. THe higher the alkaline concentration is, the more stable the dynamic IFT (Eq) between crude oil and alkaline water; The effect of biopolymer on the alkaline water flooding is especially sensitive, which is favourable to the decrease of the dynamic IFT.
