摘要
CMR核磁共振测井资料处理与应用的目的是对处理成果进行分析,识别储层,区分可动流体性质,计算地层渗透率,束缚水饱和度及含油气饱和度,并对处理成果进一步分析,总结应用,特别是研究如何开展CMR油气水识别应用。文章探讨如何利用CMR资料识别油气水层和确定储层主要物性参数方法。利用对某实际区域的一口井的CMR资料进行实际处理得到的有效孔隙度,渗透率,束缚水饱和度和T2时间分布等来划分低阻油气层和区分油气水层,其结果均与现场提供的试油录井资料吻合较好,表明CMR资料在储层地质应用方面有独到之处。
The purpose of CMR nuclear magnetic resonance logging is to analyze outcome, identify reservoir, distinguish fluid property, calculate formation permeability ,bound water saturation and hydrocarbon saturation, and further analyze, generalize, apply, particularly research how to develop CMR oil/gas/water recognition and application. This paper mainly researches on how to use CMR information to identify oil/gas/water reservoir and find method of obtaining main physical property constants. Using the effective porosity, permeability, bound water saturation and T2 distribution from true processing CMR data, we can separate low-resistivity reservoir and identify oil/gas/water reservoir. The result of this is greatly in accordance with the field log data, which demonstrates CMR's distinctive position in geology application.
