摘要
文章从氧活化测井基础出发,建立了测井仪器探测模型,应用中子活化和探测函数计算出了不同流速情况下的时间谱,计算的结果与实际测量的时间谱具有良好的一致性,证明该计算方法是可行的。该模拟计算方法可以为氧活化仪器设计和刻度系数的确定提供理论基础。
Based on the principle of oxygen activation logging,the theoretical model is built up and neutron activation and sensing function is derived. Using this function,the time spectrum of activated fluid at various speeds is calculated.The consistency between theoretical and fields results verifies the method.It will be very useful in the tool design and the determination of the calibration.
