在模拟辽河兴隆台油田地层条件下研究了聚合物对碱/原油动界面张力的影响,和碱/聚合物长期相互作用后与原油间平衡界面张力的变化。使用了不同类型的碱(NaOH和Na_2CO_3)和聚合物(不同水解度的HPAM和Xanthan).本工作发现:聚合物能降低碱/原油动界面张力最低值和稳态值,碱/聚合物溶液老化后与原油间平衡界面张力降低。
Under the conditions of simulating the Xinglongtai oilfield in Liaohe, the influence of the polymer on the dynamic tension of the alkali / crude oil interface and the change of the equilibrium interfacial tension with the crude oil after long-term alkali / polymer interaction were studied. Different types of bases (NaOH and Na 2 CO 3) and polymers (HPAM and Xanthan with different degrees of hydrolysis) were used.This work found that the polymer can reduce the minimum and steady-state value of alkali / After aging, the balance of interfacial tension with crude oil decreases.
