摘要: 利用薄板模型,对6种不同裂缝分布的水驱油过程进行了物理模拟。通过对不同裂缝分布下水驱油效果的分析比较,得出了不同裂缝形态水驱油的规律。指出裂缝方向与渗流方向的关系对驱替效果的影响最大;裂缝的长度以及长度的配置对驱替效果也有影响,但居于第二位。

Abstract: The water-oil displacement procedures of 6 types of different fractural distributions were physically modeled using slice models,obtaining the patterns of water-oil displacement in different fractural geometric configurations compared with their analytical effects. It shows that the relation between fractural orientation and percolating direction is of the maximum influences in the displacement effects; the lengths of fractures and the configurations in length are in the second important effects on the water-oil displacement.

Key words: recovery factor, physical modeling, fractured reservoir, parallel fracture
