| 摘 要： | 在前人烃类物质微渗漏机制研究基础上，建立了烃类物质微渗漏的概念模型，并且推导了烃类物质垂向运移的动力学模型。在动力学模型的基础上，通过数值模拟验证了烃类物质胶体气泡上升机制的合理性，并计算了不同情况下烃类物质垂向运移的平衡时间，进一步验证了烃类物质气泡上升机制满足运移速度快、流量少的特点。

| Abstract: | After thorough review of hydrocarbon microseepage mechanisms, the paper worked out a concept model of hydrocarbon as well as a dynamic model. In light of the dynamic model, we validated the gas-bubble ascent mechanism. At last we computed the equilibrium time of vertical migration for different kinds of hydrocarbon, and validated that the gas-bubble migration mechanism satisfies both of the rapid vertical velocity and relatively low flux that is required by microseepge phenomena. |

| Keywords: | hydrocarbon microseepage vertical migration dynamic model numerical simulation |
