摘　　要：针对胜利孤东油田的实际情况，通过相态试验、动态界面张力测定、吸附与模型驱油试验，研究了Ｔｗｅｅｎ８０／碱／部分水解聚丙烯酰胺复合驱油体系的性能，提出了复合驱油体系配方：０．３％Ｔｗｅｅｎ８０＋１％碱（Ｎａ２ＣＯ３∶ＮａＨＣＯ３＝１∶１）＋０．１％ＰＨＰＡＭ（３５３０Ｓ）。研究结果表明，本文提出的复合驱油体系能与胜利孤东油田原油形成中相乳状液，动态界面张力为１０－４ｍＮ／ｍ数量级，是一种较好的驱油体系。A new alkaline/surfactant/polymer flooding solution for Gudong pilot test is formulated on the basis of experimentally determined optimum composition variables and consists of 1. 0% Na2CO3 +NaCO3(1 : 1 ),0. 3%Tween-80, 0. 1% Pfizer's 3530s,and 0.4 % NaCl. The characteristics of the experimental ASP-solution are as follows:the transient interfacial tension between the solution and the crude (acid value～3mg KOH per gram oil) - 10-4mN/m,the adsorption of Tween-80 from the solution- 4. 35 mg/g oily sand,the total alkaline consumption -7. 08 mg/g oily sand. In laboratory core tests with the ASp-solution over 45% residual oil after water flooding is recovered.
