脉冲中子氧活化测井的非接触测量能力,使它在常规生产测井仪难以有效解决的某些特殊问题上,独具优势。本文简述了脉冲中子氧活化测井仪的测量原理,通过对现场实例的应用分析,表明氧活化测井对检测水井封隔器密封性、油、套管漏失等工程问题中发挥重要的作用。
The non-contact measurement capability of pulsed neutron oxygen activated logging makes it unique on certain special issues that conventional production logging tools can not effectively address. In this paper, the principle of pulse neutron oxygen activation logging tools is briefly described. By analyzing the application of the field examples, it is shown that oxygen activation logging plays an important role in detecting sealing problems of well packer, oil and casing leakage, effect.
