黏土矿物预测方程的建立及在东营油田的应用

Establishment and application of the prediction equation of clay minerals

  • 摘要: 为了使测井资料更多应用在地质研究实践中,采用测井数据预测黏土矿物的种类和含量,并研究黏土矿物在不同沉积环境下的富集规律和演化特征。以东营凹陷为研究区,在测井参数和黏土矿物之间进行多元回归,得出预测黏土矿物的4个多元回归方程。通过计算东营凹陷9口典型井沙三下顶西和沙四上顶面的黏土矿物,认为黏土矿物的富集符合沉积环境的变化,并且随埋深增加,具有伊蒙混层向伊利石演化的特征。

     

    Abstract: To make logging data more applied in geological study practice, well logging data were used to predict the type and content of clay minerals, and the enrichment regularity and evolution characteristics of clay minerals in different sedimentary environments were studied. By taking Dongying sag as the research area, four multiple regression equations for predicting clay minerals were obtained by means of multiple regression between logging parameters and clay minerals. It is believed that the enrichment of clay minerals conforms to the changes of sedimentary environments and the evolution from illite –smectite mixed layer to illite as the buried depth increased is evident through calculating the clay mineral content of the top surface from the lower part of Sha–3 member to the upper part of Sha–4 member in 9 typical wells of Dongying sag.
