It is suggested that the emulsify is formed when the oil on the water is stretched and stacked repeatedly by the wave, during which the water is mixed with the oil and entrain into the oil; particle asphaltene forms machinery protection film between oil and water, which stabilizes the water in the oil; the asphaltene film is formed through the accumulation when the water cohere; the resin of high viscosity can intensify the film.

通过对文献资料数据和不同观点进行分析及油水运动特点的实验观察，对溢油乳化物形成机制提出新的见解认为：乳化物是原油在波浪作用下反复拉伸和堆积中发生油水混合、水被夹带入油中而形成；颗粒态沥青质在水滴外形成机械保护膜将其稳定，它是水滴凝聚受阻时在油水界面积累而成，胶质的高粘性强化保护膜起到辅助作用。
