摘　　要：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。Fault block Qiao 29 is light crude oil and stratied oil reservoir,which is highly heterogeneity.Injection wells were injected in full strata.The waterl ine were pushed non homogeneously,the major injected water got into minor high permeable formation,and made the formation produced adequatedly,But the mid l ow p ermeable formation were produced non adequatedly,even no production,so the kind s of oil reservoir have lots of remaining oil,which is the focal point of product ion in the future.This paper analyzed the significance and necessary of water sh utoff in faull block Qiao 29,which defined the economic limit of water shutoff in different reservoirs or liquid producing capacity on the basis of the ways,s uch as econmic evaluation and reservoir engineering.
