Oil Saturation in Rock Cuttings Measured by Nuclear Magnetic Resonance
核磁共振岩屑含油饱和度分析技术的实验研究

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
