Based on the above cases, aiming at the actuality and practical cases of low-resistivity oil/gas reservoir log interpretation and evaluation in this thesis, beginning with analysing the intrinsic characteristics and physical properties of low-resistivity oil/gas reservoirs, all kinds of formation origin and mechanism of low-resistivity oil/gas reservoirs are analysed systematically and a great many of examples are given. Then the low-resistivity oil/gas reservoirs are classified by their formation origin. By setting up all kinds of interpretation models of low-resistivity oil/gas reservoirs, discussing and studying the low-resistivity oil/gas reservoir interpretaion and prediction methods, a set of practicable and systematic well logging interpretation and evaluation methods is obtained.

鉴于此，本文针对低电阻率油气储集层测井解释和评价的现状与实际情况，从认真分析低电阻率油气储集层的基本地质特征和物理性质着手，系统地分析了低电阻率油气储集层的各种成因和机理，并例举了大量实例，在此基础之上，对低电阻率油气储集层进行了科学的成因分类，建立了各种低电阻率油气储集层的解释模型，并对低电阻率油气储集层的测井精细解释与评价预测方法作了深入的探讨和研究，形成了一套较为实用的低电阻率油气储集层测井精细解释与评价方法系统。

我们测定了斑腿蝗科10亚科20种蝗虫和其它蝗科3种蝗虫的16S rDNA序列片段，并从GenBank中下载了斑腿蝗科3种、其它蝗科10种及蚱总科2种的16S rDNA相应序列片段，然后对这共计38种蝗亚目昆虫的16S rDNA序列片段进行了同源性比较，以其中2种蚱作外群构建了蝗总科的分子系统树，得到的结论如下：1斑腿蝗科并非是一单系群。2该科中的切翅蝗亚科、稻蝗亚科、黑蝗亚科、秃蝗亚科、卵翅蝗亚科、蔗蝗亚科均不是单系群，分子系统树的聚类结果与基于形态特征的斑腿蝗科的分类体系有较大的出入。3支持将黑蝗亚科和秃蝗亚科合并为一个亚科——秃蝗亚科。4卵翅蝗、伪稻蝗和稻蝗三者有很近的亲缘关系。
