摘　　要：脉冲中子-中子(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,进而来获取储层剩余油饱和度的测井技术。它的测量原理、数据采集和处理方式与常规中子寿命测井相比均有独特之处。通过其在青海油田大量的测井实践以及资料解释方法的研究,认为该项测井技术可在水淹层评价,寻找潜力层和未动用层,有效识别气层,识别低阻油层,低孔低渗储层评价,复杂岩性识别等地质应用方面发挥出重要作用。Pulse Neutron-Neutron(PNN) logging is a through records remaining number of heat after capture reaction with stratum and obtain Remaining oil saturation of logs technology.Compared to Neutron-lifetime logging,It's principle、data collection and mode of processing is distinctive.We do a lot of logs practice and research on interpretation method in QingHai oilfield.The application of the technology in QingHai Oil Field showed that it had a series functions in geological application,such as flooded area determination,remaining oil layers seek,gas layer recognition,low resistivity recognition,low porosity and low permeability recognition,complication lithology distinguish,etc.
