Abstract Small-scale experiments were performed in a custom-made laboratory rig to study the in-situ burning (ISB) behaviour for oils that were chemically confined using herders. The burning efficiency, the global mass burning rate and the regression rate are all reported. Two commercially available herding agents (ThickSlick 6535 and OP40) were used to thicken two crude oils (Alaska North Slope (ANS) and Grane), and their respective artificial water-in-oil emulsions. The burning behaviour during ISB was found to be affected by the oil type and weathering degree. However, no dependencies were observed on the burning behaviour regardless of the herder type. The chemical confinement resulted in quantitative lower burning results (burning efficiency, mass burning rate and regression rate) as compared to physical confinement. Scaling dependencies were also found as a function of the oil amount or oil diameter with contrasting qualitative dependencies between the results from experiments with respectively chemical and physical confinement.

使用化学约束原油在水上进行小规模原位燃烧 (ISB) 实验

摘要 在定制的实验室设备上进行了小规模实验，以研究使用 Herders 进行化学限制的油的原位燃烧 (ISB) 行为。燃烧效率、全局质量燃烧率和回归率都被报告。两种市售的驱赶剂（ThickSlick 6535 和 OP40）用于增稠两种原油（Alaska North Slope (ANS) 和 Grane）及其各自的人工油包水乳液。发现 ISB 期间的燃烧行为受油类型和风化程度的影响。然而，无论牧民类型如何，都没有观察到对燃烧行为的依赖性。与物理限制相比，化学限制导致定量较低的燃烧结果（燃烧效率、质量燃烧率和回归率）。
