饱和水介质中石油运移解析模型及结果分析

以石油运移通道几何形状比较规则、渗透率分布比较均匀而且运移通道被水饱和为假设条件，建立了石油运移解析模型，用于在不同运移通道性质条件下，评价运移速度、运移量、运移距离随时间的变化关系。分析计算结果发现，在运移过程中，石油的黏度越大，运移量越小、运移距离越短、运移速度越慢，而且速度的递减也越快；压差越大，石油运移的距离越长、运移量越大，同时运移速度也越快，速度递减缓慢。

The analytical model of oil migration in water saturated media and result analysis

On the assumption that the geometrical shape of petroleum migration channel is regular, the distribution of permeability is Well-proportioned and migration channel is water saturated , an analytical model of Petroleum migration is established in order to evaluate the relationship between petroleum migration speed, quantity, distance and time under the situation of different migration channels. It can be obviously concluded from our research that, the higher the oil's viscosity is, the less the oil's migration quantity is; the shorter the migration distance, the slower the speed of petroleum migration and the quicker the decrement of migration speed. At the same time, the bigger the Pressure difference is, the larger the oil's migration quantity is; the longer the migration distance, the faster the speed of petroleum migration and the slower the decrement of migration speed.
