研究了NaOH‐HPAM、乙二胺‐HPAM两种体系与稠油间的界面张力，以及体系的乳化性能、黏度、驱油效率和微观驱替机理。结果表明，在质量分数0.65％的 NaCl溶液中，乙二胺降低油‐水界面张力的能力强于NaOH ，乙二胺‐HPAM体系的黏度远高于NaOH‐HPAM体系。乙二胺与稠油容易形成较稳定的水包油乳状液，而NaO H与稠油形成的乳状液中的油滴会迅速聚并。这主要是由于乙二胺与石油酸形成不同类型表面活性剂和不增加矿化度的结果。由于聚合物的增黏作用，两种体系都能获得较大的波及系数。同时，在油湿情况下，乙二胺‐HPAM 溶液能够渗入稠油形成不连续水滴，不连续水滴中包含大量被乳化的小油滴，出现二重乳化现象，且在后续驱替中产生明显的乳化携带作用。NaOH‐HPAM 溶液也能渗入稠油形成不连续水滴，但由于乳化携带作用差，洗油效率较低。综合对比，乙二胺‐HPAM 和NaOH‐HPAM 相比在提高采收率中有较大优势，且有机碱有较大的应用前景。
研究瞭NaOH‐HPAM、乙二胺‐HPAM兩種體繫與稠油間的界麵張力，以及體繫的乳化性能、黏度、驅油效率和微觀驅替機理。結果錶明，在質量分數0.65％的 NaCl溶液中，乙二胺降低油‐水界麵張力的能力彊于NaOH ，乙二胺‐HPAM體繫的黏度遠高于NaOH‐HPAM體繫。乙二胺與稠油容易形成較穩定的水包油乳狀液，而NaO H與稠油形成的乳狀液中的油滴會迅速聚併。這主要是由于乙二胺與石油痠形成不同類型錶麵活性劑和不增加礦化度的結果。由于聚閤物的增黏作用，兩種體繫都能穫得較大的波及繫數。同時，在油濕情況下，乙二胺‐HPAM 溶液能夠滲入稠油形成不連續水滴，不連續水滴中包含大量被乳化的小油滴，齣現二重乳化現象，且在後續驅替中產生明顯的乳化攜帶作用。NaOH‐HPAM 溶液也能滲入稠油形成不連續水滴，但由于乳化攜帶作用差，洗油效率較低。綜閤對比，乙二胺‐HPAM 和NaOH‐HPAM 相比在提高採收率中有較大優勢，且有機堿有較大的應用前景。

a comparative study of the oil‐water IFT , emulsification properties , viscosity , displacement efficiency and micromodel displacement mechanism was conducted for the systems of ethylenediamine(EDA)‐HPAM and NaOH‐HPAM .The results showed that the ability of EDA to reduce IFT was stronger than that of NaOH in NaCl solution of mass fraction 0.65% .The viscosity of EDA‐HPAM was higher than that of NaOH‐HPAM .EDA can emulsify the heavy oil to create stable O/W emulsion ,while the oil droplets of the emulsion created by NaOH and heavy oil could coalesce together rapidly ,due to the different in‐situ surfactant and no salinity addition created by EDA .The EDA‐HPAM solution could penetrate into oil phase to create discontinuous water droplets containing some small emulsified oil droplets ,and then the subsequent water phase could carry much oil droplets to recovery oil .Although NaOH‐HPAM solution could also penetrate into oil to create discontinuous water droplets , the effectiveness of entrainment was slight and the displacement efficiency was low .Accordingly ,EDA‐HPAM has an advantage in oil recovery over NaOH‐HPAM system .Moreover ,organic alkaline has a good application prospect .
