摘要
脉冲中子-中子(PNN)测井是利用直接测量热中子通量进而计算剩余油饱和度的测井技术。该项技术通过测量地层中热中子数量随不同时间的变化关系,用特有的处理手段和解释方法求取含油饱和度等多种地层参数。介绍了该项测试技术的测试原理及仪器的技术参数。通过在大港油田70多口井次的应用实例.阐述了该测试技术对含油饱和度的测试、寻找潜力层、低电阻率油层的识别等方法及应用,为油田的后期开发及剩余油开采提供了一种监测手段。
Pulsed neutron neutron (PNN) logging measures formation parameters of oil saturation and porosity, through relation of thermal neutron population changing with time in the formation by its own unique processing and interpreting methods. The PNN tool, which imported by Dagang Oilfield in June 2004 is the first imported one in China, has been run for more than 70 well-times, and provides one of the monitoring measures for production of maturing developed oilfield and its remaining oil. Introduced are the principle of the PNN logging and specifications of the tool, as well as applications in oil saturation evaluation, water flooded zone identification, low resistivity reservoir identification and potential zone search in Dagang oilfield.
