PNN测井技术及其应用分析

PNN测井是一种利用测量地层中剩余热中子数量随时间变化关系，从中提取地层的宏观俘获截面，计算储层的剩余油饱和度的方法；其采集方式区别于其它脉冲中子测井，也具备独特的数据处理技术。文章介绍了PNN测井原理、解释方法，并结合实例认为：地层的宏观俘获截面是表征地层中子特性的参数，与地层岩性、裸眼井的伽马曲线有很好的对应关系；PNN测井资料解释须参考生产井史、邻井注水动态资料，才能得出准确的结论。

PNN logging technology and application analysis

PNN logging technology is the method that utilize and measure the relation that the quantity of surplus thermal neutron changes over time in the stratum,draw the macroscopic capture section of the stratum from it,calculate the degree of saturation of surplus oil of storing layer.Its gathering way distinguishes between other pulse neutron well logging,also has the unique data technology.This paper introduced the PNN logging principle,the explanation method,and unify the example to believe that the stratum ma...
