舞阳、襄城凹陷盐湖相地层岩性识别方法研究

Lithologic identification methods for strata of salt lake facies in Wuyang-Xiangcheng depression

针对舞阳、襄城地区盐湖相地层的特点、勘探情况及测井资料现状,采用数理统计、神经网络分析技术等一些近代数学方法,成功地研制了一套定性、定量识别储层岩性的方法,并建立了储层岩性测井参数解释图版和一套适应该地区岩性的测井系列。为全面准确地解释该地区地质情况提供了可靠的手段。

In view of the characteristics of strata of salt lake facies in Wuyang - Xiangcheng depression, the exploration situation and the available logging data, some modem mathematical methodologies, such as mathematical statistics and neural network analysis, are used to successfully develop a set of quantitative and qualitative litholigic identification methods. An interpretation chart for interpreting reservoir lithology with log parameter is established and a logging suite suitable for the lithologies in the study area is presented. These methods can be used to accurately interpret lithologies in the study area.
