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 discussed the method and principle of using NMR logging to evaluate the degree of reservoir damage and proposed to disclose the degree of reservoir pollution by comparing the surface core mercury intrusion, physical property measurement (or porosity logging) and nuclear magnetic resonance logging results Nuclear magnetic resonance logging technology to evaluate the extent of damage to the reservoir method and the application of a well in the Tarim Oilfield case analysis, the results of core flow and the sensitivity of the experimental results are consistent.
