摘要(Abstract)：
利用核磁共振岩样分析技术对岩心、岩屑测量进行的实验研究结果表明,核磁测量得到的各项测量参数均具有较高的测量精度;利用该技术在多个油田进行的现场应用效果表明,核磁测量得到的结果能够满足工程上快速划分和评价有效储层的精度要求,核磁解释结果与实际生产结果吻合,核磁共振岩样分析技术可以推广应用。
Lab research of NMR rock sample analysis technique applied in core and cuttings measurement show that all measurement parameters obtained from NMR have high accuracy in measurement.Field application in many oilfields shows that NMR measurement result can meet the accuracy standard of quick division in engineering and effective reservoir evaluation,and can match the real production results.So this technique can be popularized in application.
