| 摘要: |
| 旅大5-2油田经过多年开发,东二上段部分井区储层非均质性强、油水流度比大,造成该区块层间动用不平衡。为改善注水井吸液剖面,抑制注入水突进,增加中低渗透层原油储量动用程度,减缓2号块东二上段含水上升速度,对旅大5-2油田2号块东二上段开展弱凝胶调驱技术室内研究及现场实施。结果 表明,弱凝胶调驱收到了较好的效果,为海上油田提高原油采收率提供了新的思路和方法。 |

| Abstract: |
| Strong reservoir heterogeneity and high water-oil mobility ratio of LD5-2 oilfield EdⅡu area for many years led to disequilibrium between layers. In order to improve profile of injection well, control break through of injected water, startup producing reserves of mid-low permeable interval, and decrease the water ratio, laboratory study and field application of weak gel profile control technology were conducted in LD5-2 oilfield EdⅡu area. The results showed that weak gel obtained good effect and provided new ideas and methods for enhancing oil recovery in offshore field. |
| Key words: LD5-2 oilfield weak gel profile control enhanced oil recovery |
