摘　　要：研究了驱油剂对三元复合驱模拟采出液破乳脱水效果的影响规律,单一的碱、表面活性剂和聚合物对脱水率和水色有较大的影响;3种驱油剂之间存在明显的协同作用,对脱水率和脱出水色的影响很大。显微照片验证了含驱油剂的乳液存在多重乳状液。根据破乳机理和三元复合驱采出液的特点,提出了合成新型破乳剂的研究思路。The influence law of the oil displacement agents on demulsification/dehydration of the simulative produced liquid during ASP flooding was studied. Single alkali or surfactant or polymer had a biggish influence and the combinations of alkali, surfactant and polymer had a very big influence on dehydration rate and water color of the simulative produced liquid. There was a synergism among alkali, surfactant and polymer. On the base of the micrograph of the emulsion containing the oil displacement agents, it was ascertained that there were multiple emulsions in the produced liquid. According to the demulsification mechanisms and the characteristics of produced the liquid, some few study routes about the demulsifiers for the produced liquid were suggested.
