| 摘 要： | 在考虑启动压力梯度的基础上,建立了低渗透油层中一维两相驱替的数学模型,并进行了数值求解。结果表明:在低渗透油藏开发中,启动压力梯度的存在,造成地层压力的增加和平均含水饱和度的降低,不同的驱替方向,对低渗透油田有不同的开发效果,启动压力梯度是一个影响低渗透油田开发特征的重要因素。

| Abstract: | A mathematical model of one dimension displacement was established in the base of taking into account the starting pressure gradient, and then a solution of equation was solved. The results indicated that in the lowermeability reservoirs, the presence of the starting pressure gradient cause to the increase of the formation pressure and the decrease of the average water saturation. Different direction of the oil displacement broughtthe different effect in the low-permeability reservoirs development. |

| Keywords: | low-permeability displacement apparent viscosity starting pressure gradient |
