The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.

So supported by well core experimentation, the *** analyzed the logging response feature and mechanism of thin bed, and point out that many factors can affect the logging response of the reservoir, the main factor which mostly influence the logging response is the thickness of thin layer, and the content of carbonite have a great influence on the response of 3-porosity logging.we make use of core experimentation, combined with logging material, firstly the *** do the lithology correction and thinckness correction for resistivity curves, and based on the content of mud that derived from the core experimentation, the *** present the thickness correction model of gamma-ray logging and self-potential logging, and choose the appropriate ways to compute the carbonate content and using the value of mixed frame in order to correct the influence from the carbonite, based on this, the *** gives a effective methods to correct the thickness influence for 3-porosity logging.

本文首先以岩心实验结果为依据，对研究区薄层的测井响应特征和机理进行了分析，指出多种地质因素影响着储层的测井响应特征，而层厚是影响测井响应最主要的因素，且碳酸岩含量对三孔隙度测井的影响很大。利用岩心实验分析资料，结合测井资料，首先对电阻率测井曲线进行了岩性的校正和层厚校正；利用岩心分析泥质含量，研究了自然伽马和自然电位的层厚校正方法，并建立了层厚校正模型；在有效计算储层碳酸岩含量和混合骨架参数值的基础上，研究了针对碳酸岩含量对测井曲线的影响进行校正的方法，进而提出了一套对三孔隙度测井曲线的薄层层厚影响的校正模型。
