Concretely, starting from a short sequence primal masks possessing Hermite interpolation properties, a necessary and sufficient conditions such that primal masks satisfies the preassigned order of sum rules are established, then a dual masks with short support, symmetry and any preassigned order of sum rules is constructed, it follows that two multiscaling functions are obtained and then multiwavelets and dual multiwavelets are derived. From which, a general design framework is obtained for constructing biorthogonal multiwavelets system with multiplicity 2r associated with Hermite interpolation functions.

This word, first found in English in 1766, came from French cabriolet, of the same meaning, which in turn was derived from cabriole,"caper," because the vehicle moves along with a springing motion. Cab, the shortened form, was applied to other vehicles as well, including eventually public conveyances.

这一单词最早于1766年在英语中发现，来源于具有同一种意思的法语cabriolet ，它依次来源于cabride，因为这种车辆移动时有跳跃的运动；缩写形式cab 还可以适用于其它的车辆，包括最终的公共运输工具；被安装了自动计费器的车辆，开始是马拉的，后来装上马达，被称作taxameter cab 1899年）、 taximeter cab (1907年）和 taxicab 1901年）。

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。
