| 摘 要： | 鄂尔多斯盆地上古生界是天然气的重点储集地层,成岩强度定量化是地层成岩作用研究的基础.粘土矿物是地层成岩信息的载体,根据蒙皂石-伊利石系列粘土矿物在成岩过程中间层比与结晶指数的相应变化,其在成岩演变过程中自身具有可度量性,可作为碎屑岩地层成岩强度的标尺.由此建立的地层成岩定量化系统为进一步揭示地层成岩演化规律提供依据.

| Abstract: | The establishment of the quantified system on the diagenesis intensity of the clastic strata in Upper Paleozoic of Ordos Basin aimes to provide a kind of quantification investigation project for the diagenseis in this region.It has been proved that the diagenetic grade of clay mineral can be quantified by analyzing interlaying ratio and crystallizing index.By making the diagenetic grade of clay mineral as measures and weights of diagenesis intensity and defining absolute diagenesis index,people can quantitatively research the evolutionary distribution rule and the space-time matching relation of diagenesis intensity of the clastic strata being in different horizon or region and having different lithology during geology history in Upper Paleozoic of Ordos Basin. |

| Keywords: | diagenesis intensity diagenesis index interlaying ratio crystallinity |
