在生物学、药物学和食品科学中，共焦距显微镜和低温扫描电子显微镜是常用的技术手段。尽管这些技术很少应用在石油工业，但我们发现其样品与生命科学的样品有许多相似的地方。低温扫描电子显微镜（cryo－SEM）和共焦距激光扫描显微镜（CLSM）非常适合于解释决定乳状液和悬浮液特性的基本相互作用。由于环境和经济的原因，油包水和水包油乳状液在石油加工、分解和分离过程中都是很重要的。无论分散相是否被固体颗粒所稳定。在确定乳状液的稳定性或组分的分离难度方面，颗粒的表面特性、分散相的粒度分布都是很重要的参数。在决定化学和物理分离方法是否有效的过程中，显微镜是重要的第一步。
In biology, pharmacology and food science, confocal and cryogenic scanning electron microscopy are common techniques. Although these technologies are seldom used in the oil industry, we find many similarities between their samples and those of life sciences. Cryo-SEM and CLSM are well suited to explain the fundamental interactions that determine the properties of emulsions and suspensions. For environmental and economic reasons, water-in-oil and oil-in-water emulsions are important in the petroleum processing, decomposition and separation processes. Whether the dispersed phase is stabilized by solid particles. The surface properties of the particles and the particle size distribution of the dispersed phases are all important parameters in determining the stability of the emulsion or the difficulty in separating the components. Microscopy is an important first step in determining whether the chemical and physical separation methods are effective.
