脉冲中子氧活化测井技术的优势

Advantages of Neutron Oxygen Activation Logging Technology

通过分析脉冲中子氧活测井技术适用性,结合典型脉冲中子氧活化及同位素测井实例,表明氧活化测井技术具有影响因素少,不受井内液体性质、管柱结构影响,能够精确查找管柱漏失点,验证封隔器是否失效,消除粘污影响,准确给出各层吸入情况等技术优势。

By analyzing the application of pulsed neutron oxygen activation logging technology, combined with the typical cases of the pulsed neutron oxygen activation and isotope logging, it shows that oxygen activation logging has less influence factors, and is not affected by the liquid properties and string structure. It can accurately locate the leakage point of the string structure, verify the failure of the packer, and eliminate the influences of the isotope contamination. At last , it can be used to determine the injection volumes of each interval accurately.
