陆相储层岩石核磁共振物理特征rn的实验研究

摘要

The relation of rock petrophysical and nuclear magnetic resonance (NMR) properties were investigated systematically on the continental sedimentary rocks existing significantly in China. Methods translating NMR measurement results to petrophysical parameters that conventionally used in petroleum industry were discussed in detail. Differences between conventional core analysis and NMR measurements were compared. Experimental results were compared as well as with some overseas ones according to Chinese sedimentary rock characteristics. Research results are useful in the application of NMR to petroleum industry in China.%以中国大量存在的陆相沉积岩为对象，系统研究了岩石核磁共振特征与岩石物理性质的关系，详细阐述了将核磁共振测量参数正确地转化为石油工业可直接应用的油层物理参数的方法，对比阐明了核磁共振测量结果与常规岩心分析的异同.针对我国陆相沉积岩核磁共振的特有性质，与国外的一些研究结果进行了对比. 本文研究结果对在中国开展核磁共振石油工业应用具有重要意义.
