| 摘 要： | 利用核磁共振成像技术、图像处理技术进行了岩心分析方法研究。阐述了核磁共振成像原理及图像处理软件功能。通过岩心测试分析计算方法研究,建立了核磁共振成像测试分析计算岩心内部结构,岩心孔隙度参数和孔隙度分布图像、渗透率分布图像,可动流体百分数图像,油水识别图像方法。表明:核磁共振图像不仅能够给出岩心总孔隙度,渗透率物性参数,而且能够给出岩心孔隙度,渗透率分布信息。根据可动流体百分数图像,可观察到可动流体在岩心中的分布情况。核磁共振成像油水识别方法,给出了油水在岩心中的分布情况,并可计算油、水饱和度。建立的岩心磁共振成像分析研究方法,可应用于油田储层评价,开发试验以及提高采收率研究。

| Abstract: | Study of method in core analysis by MRI and Image processing technology.Principle of NMR imaging and Image processing function are described.Through the study of testing rock and math method,and established the methodsto analysis formation structure,porosity and porosity distribution image,permeability and permeability distribution image,movable fluid percentage image,identification of water and oil image.The results indicated that testing rock by using MRI technology not only determine porosity and permeability parameter,but observe porosity and permeability distribution image also.Movable fluid in rock is observed by movable fluid percentage image.The method of identification of water and oil give distribution of water and oil in rock,oil and water saturation is calculated.Method in core analysis by MRI can apply to reservoir evaluation,development, experiment,enhance recovery ratio research in oil field. |
