摘　　要：在前人研究气泡的基础上,把气泡的两阶段形成理论应用于油滴的形成,同时考虑了油自身的特性,包括油的密度,表面张力和粘性。基于动力学平衡关系和合理的假设,利用一定的半经验和半理论的公式,预测油滴从管口脱离后的直径。利用CCD作为工具,在水槽中模拟静止海水中海底管线微孔处连续泄漏出单个油滴的形成过程,得到实验值。把油和气体的计算值与实验值进行比较,吻合良好。Based on the research of gas bubble and application for the formation of oil drops, at the same time, the properties of oil are considered, including density, surface tension force and viscosity. Based on the overall force balance acting on the bubble and reasonable assumptions, a semi-empirical and semi- theoretical model is present to predict oil drop size after its departure from hole. By the way of CCD, the formation of oil drops successive spilled from seabed pipeline is simulated in the aquarium. The predicted and the experiment results have a good agreement.
