摘　　要：讨论了应用核磁共振测井评价储层伤害程度的方法和原理,提出了通过对比地面岩心压汞、物性测量(或孔隙度测井)与核磁共振测井结果来揭示储层污染程度,或者通过核磁共振测井的时间推移技术来评价储层伤害程度的方法,并应用塔里木油田的一口井进行了实例分析、结果与岩心敏感性流动实验结果相吻合。This paper discusses a method of using nuclear magnetic resonance log (NMR) in formation damage e-valuation. It detects the formation damage condition by comparing the NMR log data to surface core mercury injection test and petrophysical properties (or porosity log), or by the time delaying method. This method is used for site formation damage evaluation in a well of Tarim Basin, and the result is in correspondence with the core flow test.
