现代核磁共振测井技术的发展为提高利用测井资料进行油气层评价解释的精度提供了一种新的有效的手段;对于碳酸盐岩等复杂岩性油气藏,由于其储集空间复杂、非均质性强等因素,用常规测井技术难以进行准确描述。岩心核磁共振基础实验分析研究是核磁测井资料采集、处理解释分析及应用的基础。本文从岩心核磁实验资料入手并结合核磁测井实例探索了核磁技术在碳酸盐岩的应用,并很好地解决了在储层评价及储层参数研究中存在的难点:含烃饱和度的计算、确定孔隙度下限值和区分束缚孔隙流体和可动孔隙流体,在复杂多样的碳酸盐岩储层中效果不错。
The development of modern NMR logging technology provides a new and effective method for improving the accuracy of logging data interpretation and interpretation. For complex lithologic reservoirs such as carbonate rock, due to the complexity of reservoir space, Heterogeneity and other factors, using conventional logging technology is difficult to accurately describe. The core NMR experimental analysis is the basis of NMR data acquisition, processing, interpretation and application. This paper starts with the core NMR data and explores the application of nuclear magnetic resonance technology in carbonate rock combining with NMR logging examples. It also solves the difficulties in reservoir evaluation and reservoir parameter research: hydrocarbon saturation Calculating and determining the lower limit of porosity and distinguishing between bound pore fluid and movable pore fluid are good results in a variety of carbonate reservoirs.
