摘要
在多元泡沫复合驱油实验研究的基础上,通过对渗流机理、渗流规律的分析,根据质量传输流体力学、化学动力学、物质平衡原理和对泡沫上浮运动等机理的深入研究,建立了多元泡沫化学剂复合驱油渗流数学模型.结合对泡沫流动机理和物理化学性质的实验研究,给出了相应的数学描述模型方程.数值模拟结果表明,该模型能较好地反映了渗流物理实质.
According to the main multi-component foam drive mechanism and various physicochemical phenomena taking place in the EOR method, such as phase change, rheological property of foam phase, and foam vertical shallow, a series of mathematical models for describing the parameters of multi-component foam drive were established on the basis of foam drive mechanism and experimental results. The foam flowing rules in porous media were described in these models. The mathematical description of this complicated flow for multi-component foam drive was resolved. Numerical simulation results proved that the models could reveal the physical essence of porous flow.
