| 摘 要： | 利用火驱技术进行油田开发,保持高温燃烧前缘稳定推进对开发效果至关重要,而在地下多孔介质中维持火驱前缘稳定燃烧的地层燃料,是由不同碳原子数烃类构成的,火驱开发效果的好坏则主要取决于原油中是否有足够的燃料维持燃烧。不同类型油藏由于烃类含量不同,能够为火驱燃烧提供的燃料量差异也较大,从而使最终开发效果的差别也较大。为了分析在火驱过程中不同烃类的燃烧性能,通过一维物理模拟实验研究了不同烃类对燃烧效果的影响。实验结果表明:碳原子数为C_5-C_(16)的烃类是主要的被驱替组分,碳原子数为C_(17)-C_(23)的烃类部分可以充当燃料提供能量,碳原子数为C_(24+)以上的烃类是火驱的主要燃料。

| Abstract: | It was crucial to maintain the stability of high temperature combustion propulsion front for fire flooding process of oilfield development. The stratigraphic fuel for the formation of in-situ combustion was composed of hydrocarbons of different carbon numbers. The good effect of fire flooding process was related to the enough fuel for in-situ combustion. Due to the different hydrocarbons content and fuel supply, the effect of fire flooding process is different for various types of oil reservoirs. The effect of these hydrocarbons on in-situ combustion and the combustion performance of hydrocarbons were explored by one-dimensional physical simulation. The experimental results indicated that the hydrocarbons of C5-C16 was the main displacement components, the hydrocarbons of C17-C23 could act as part of fuel for energy, and the hydrocarbons over C24+ was supposed to be the main fuel of fire flooding. |
