| 摘 要： | 含油饱和度是油田勘探开发中的重要油层物理参数之一，目前油田现场岩屑常规录井方法只能定性给出岩屑的含油级别，无法给出岩屑含油饱和度的定量结果. 提出了利用核磁共振技术进行现场岩屑含油饱和度快速定量分析. 在室内实验基础上，采用添加弛豫试剂的方法进行了岩屑含油饱和度的核磁共振定量分析，研究摸索了一套利用核磁共振技术进行现场岩屑含油饱和度分析的方法，给出了弛豫试剂的优选方案，同时给出了核磁共振岩屑含油饱和度的测量精度.

| Abstract: | Oil saturation is an important physical parameter of petroleum used in petroleum exploration and development At present, the conventional method can only give the grade of oil saturation in the logging measurement of rock cuttings and can't determine oil saturation quantitatively In this paper, we present a method by which oil saturation in rock cuttings can be determined fast and quantitatively using nuclear magnetic resonance on the well site Relaxation additives were applied in determining oil saturation in cuttings under laboratory settings, and optimized The precision of oil saturation measurement in cuttings by nuclear magnetic resonance was also demonstrated |
