桥 2 9断块属稀油多油层油藏 ,非均质严重 ,笼统注水 ,水线推进极不均衡 ,绝大多数注入水进入了少数高渗透层 ,动用程度好 ,而中低渗透层动用差 ,甚至未动用 ,这部分油层剩余油多 ,是挖潜的重点。本文分析了桥 2 9断块堵水的重要性和必要性 ,利用经济评价方法和油藏工程方法确定了不同储层不同产液量条件下的堵水经济极限 ,该研究成果应用于实际符合率较高。 Bridge 29 is a thin oil and multi-reservoir reservoir, heterogeneous serious, general water injection, waterline promotion is extremely uneven, the vast majority of water into a few high permeability layer, the use of a good degree, and the use of low permeability Poor, did not even use, this part of the remaining oil reservoir, is the focus of tapping the potential. This paper analyzes the importance and necessity of blockage of block 29 in bridge, and uses the economic evaluation method and reservoir engineering method to determine the economic limit of water blockage under different production fluid rates. The research results are applied to the actual conformity Higher rate.
