O型孔隙中水驱油为微通道二相流动, 本文对孔隙半径与孔隙通道内径比为1:1的模型基于压力型流动利用Fluent软件进行了水驱油过程的数值仿真计算表明: O型孔隙水驱油过程是一个由非稳态至稳态的流动过程, 整个流场流动良好, 没有发现脱流以及漩涡等不良流动现象; 水驱油过程可以分为水相分离、水相相遇以及末尾稳流3个阶段; 随着时间的推移流场中高压区和低压区逐渐减少, 中压区所占有的范围逐渐在增大, 压力变化可作为流场稳定性评价标准. 为实际生产及后续研究提供良好的科学依据与理论基础.

O type pore water displacing oil flow is a micro channel two phase flow. Model with 1:1 pore radius and pore channels were calculated by FLUENT software based on pressure flow style for water displacing oil process of numerical simulation in this paper. The results show that the O type pore water drive oil process is a by unsteady state to the steady state flow process, the whole flow field flow phenomenon is good, no off flow and vortex and other adverse flow phenome-na; water flooding process can be the separation of water and water meet and at the end of the current three stages; reduces gradually along with the time flow in high pressure and low pressure area, occupied by the medium range gradually in-creased, the changes in pressure can be as a standard to evaluate the stability of flow field. This research can provide a good scientific basis and theoretical basis for the actual production and follow-up research.
