摘　　要：简单介绍了中子测量与地层含氢指数及地层孔隙度的关系,介绍了地层含气对中子测量的影响以及泥浆侵入对中子在含气地层响应特征的影响。分析了中子测井仪器长短源距探测器受泥浆侵入影响的差异,给出了通过对中子仪器长短源距计数率校正消除泥浆侵入影响的方法。通过实际资料验证,取得了比较好的结果。The relationship between hydrogen index, neutron logging and formation porosity had been introduced simply. The influence of gas and mud filtrate invasion on neutron logging in gas-bearing stratum has been studied. By studying the different effects of mud filtrate invasion to far receiver and short receiver of neutron logging tools, the methods for mud filtrate invasion correcting to neutron logging have been developed, and good result has been given.
