摘要(Abstract)：
理论上,油相和水相在没有表面活性物质的作用下,是不会发生乳化作用的,但在实验中发现大庆原油与水在一定程度上都发生了乳化作用。实验采用4种不同的水源分别与原油混合振荡发生了乳化作用,从各种水源与油的界面张力、原油黏度以及原油的组分和各种水源的矿化度等方面进行了研究和探讨。这些研究对于进一步认识原油与水的乳化作用、涉及的相态变化以及认识和了解驱油机理具有重要的理论和实际意义。
Theoretically,oil phase and water phase won't be emulsified without interface active agent,but the crude oil in Daqing oilfield had been found emulsified with water to a certain extent in experiments.Four kinds of water are mixed and shocked with crude oil respectively to emulsify in the experiments.The emulsification degree varies for different kinds of water.The interface tension of crude oil with the four kinds of water,viscosity and components of crude oil and salinity of water have been discussed and studied.The researches and discussion lead to a further cognition to emulsification and phase change,which has academic and practical significance in our realization of the oil displacement mechanism.
