随着注水规模的不断扩大，注水替油井的增多，在注水过程中出现的问题也越来越多，注水失效的问题逐渐凸显。从油井的静态资料出发，结合酸压曲线、注水指示曲线、生产特征和动态监测资料（压降试井曲线），初步建立地质概念模型，在此基础上，找到影响注水效果变差或失效的节点，从而采取不同的对策进行治理。通过不断的摸索总结，逐步形成了一套注水失效井的治理对策。

With the continuous expansion of the scale of water injection and the increase of oil wells exploited with water injection, more and more problems appear during injecting progress, and injection failure problems have become increasingly outstanding. A geological conceptual model is preliminarily established, with the static data of oil wells, combining with the acid fracturing pressure curves, water injection indicating curves, production characteristics and dynamic monitoring data (pressure drop testing curves). On this base, the node factors that causing injection effect variation or failure are found, and different tactics are adopted to solve that problem. Through continuous exploration and summary, one series of countermeasures for water injection failure wells has been gradually formed.
