By the use of the component sandstone electric conductivity model, the effect of the pore structure characteristic parameter to cementation exponent m and saturation exponent n in the Archie formula were studied. It can be found the cementation exponent m mainly reflects the pore space size and its sizes distribution. The m is bigger, the pore space is bigger, the throat is simpler, and the reservoir is better.
通过致密砂岩电导模型分析研究致密砂岩孔隙结构特征参数对Archie公式中的胶结指数m和饱和度指数n的影响,发现岩石胶结指数m主要是岩石孔隙空间大小及其大小分布的表征,m值越大的岩石其孔隙储集空间越大,孔喉越简单,储集性能越好;反之,m值越小,岩石储集性能越差。

The results were as follows: 1 There were 7 133 trees, belonging to 23 species and 18 genera and 13 families, and their average DBH, crown and height were respectively 27.59 cm, 4.10 m and 6.94 m. In general their average crown was relative small. 2 S, H (Shannon-Wiener index), and D of biodiversity index were small, and there were the obvious difference in those indexes among different streets, which suggested that there were certain monotone of the tree species and structure layer. 3 The dominant species mainly consisted of evergreen trees that were Ficus virens var. sublanveolata, Ficus benjamina, Roystonea regia, Terminalia hainanensis, T.

Based on fuzzy mathematics comprehensive evaluation, the toxicity of heavy metals was taken into account. The fuzzy comprehensive evaluation results by pollutant concentration exceeding standard weighting method, toxic response coefficient heck-stepping index weighting method and heavy metal toxicity sorting weighting method were compared with the potential ecological risk evaluation results. The research results showed that the evaluation results by toxic response coefficient back-stepping index weighting method could reflect the actual results more truly and accurately.
