摘　　要：PNN测井是一种通过记录发生俘获反应后地层中的剩余热中子数量,进而获取储层剩余油饱和度的测井技术。其测量原理、数据采集和处理方式均有独特之处。通过在青海油田大量的测井实践出发,总结出了一套PNN测井进行水淹层识别的综合解释方法。并在此基础上,充分利用动态监测资料对水淹层进行分级评价以及建立了区块解释标准对其进行量化解释,从而使PNN测井在青海油田剩余油测井评价中发挥出了独特而重要的作用。PNN logging is a technology of remaining number of thermal neutron through records after capture of reaction in stratum and obtaining remaining oil saturation of logs.It's principle,data collection and mode of process were distinctive.From the aspect of logging practices in Qinghai Oilfield,a method of a comprehensive interpretation of water-out reservoirs using PNN logging was summed up,on the basis stated above,water rates obtained from the dynamic data were fully used to evaluate water-out reservoirs and establish block interpretation criterion to explain the quantitative interpretation.Thus the PNN logging plays a unique and important role in remaining oil evaluation in Qinghai Oilfield.
