摘　　要：随着杏三~四区东部Ⅰ块强碱三元复合驱开发的不断深入,区块采出液含剂量的不断增加,聚合物与表面活性剂的存在使乳状液界面膜增厚、强度变大,导致三元-5转油放水站出现油水分离效果差、采出液含泡量大等问题。通过对乳状液宏观及微观特性分析,确定了采出液乳化程度增强的原因;通过对破乳剂的药剂筛选、加药方式优化和消泡剂室内优化实验,确定了现场加药类型、投加方式及加药浓度,保证了三元-5转油放水站集输系统的平稳运行。With the deeply development of alkali ASP flooding in the east blockⅠat Xing 3-4 area, the concentration of produced liquid in the block is increasing. The existing of the polymer and the surfactant make the interfacial film in emulsion thicker and harder, which make the effect of oil-water separation poorer and the number of bubbles more, and so on. In this paper, based on the analysis of the macroscopic and microscopic characteristics of emulsion, the reasons of the enhancement of the emulsification degree are determined. Through the de-emulsifier screening, the adding mode optimization and the defoaming agent indoor optimization experiment, the type of de-emulsifier, dosing method and concentration are ensured to ensure the gathering system of sanyuan-5 oil transfer and drainage station can run smoothly.
