脉冲中子氧活化测井方法是一种能测定井下水流速度的方法,它的非接触测量能力可以用于油水井监测中出现的查窜、找漏等工程技术问题。本文通过现场实例的应用分析,对氧活化测井图谱在检测水井封隔器密封性、水井查窜、找漏等工作中的应用提出了一些经验探讨。 The pulse neutron oxygen activation logging method is a method that can determine the velocity of downhole water flow. Its non-contact measurement capability can be used in engineering and technical problems such as channeling and leakage detection in oil and water well monitoring. Based on the application of field examples, this paper puts forward some experiences and discussions on the application of oxygen activated log in detecting the tightness of well packer, well checking, leakage finding and so on.
