十屋断陷登娄库组成岩作用定量化研究

Quantitative Researches of Diagenesis in the Denglouku Formation of the Shiwu Fault

为了预测十屋断陷登娄库组碎屑岩成岩阶段横向展布,本文将传统的成岩作用研究和数值模拟技术相结合,选取对成岩作用反应敏感、成岩阶段划分常用的成岩指标古地温、镜质组反射率、甾烷异构化指数、伊/蒙混层中蒙皂石含量和石英加大含量这5项参数,分别在时空领域内进行单项成岩作用数值模拟,构建成岩作用数值模拟综合模型,进而预测十屋断陷登娄库组成岩阶段横向展布。

In order to predict the distribution of the diagenetic stages in the Denglouku formation of the Shiwu fault.We combine the clastic diagenetic theory with numerical modeling and select digital modeling of diagenetic parameters that are sensitive to diagenesis and apply to divide diagenetic stages commonly,e.g.paleotemperature,vitrinite reflectance,sterane isomerization rate,smectite and authigenetic quartz concentrations,and establish an integrated model for digital diagenesis in space-time.The lateral distribution of diagenetic stages are predicted by quantitative characterization of diagenesis for the Denglouku formation of the Shiwu fault.
