核磁共振录井分析技术在吐哈油田应用效果较差,为此开展一系列基础平行实验,对核磁共振分析参数的准确性、适用性深入分析,针对山前带不同区块、不同岩性的岩屑、岩心样品进行分析、归纳、总结,认为不同扫描次数、样品浸泡后的放置时间等十个主要因素影响核磁共振录井分析的准确性,并针对存在的影响因素,提出了具体的应对方法。 Nuclear magnetic resonance logging technology is not effective in Tuha oilfield, so a series of basic parallel experiments are carried out. The accuracy and applicability of NMR analysis parameters are analyzed in depth. According to the characteristics of different zones and different lithologies Rock fragments and core samples were analyzed, summarized, concluded that ten main factors, such as the number of times of scanning and the placement time of samples after immersion, influenced the accuracy of nuclear magnetic resonance well log analysis. In view of the influencing factors, specific countermeasures were put forward method.
