利用测井数据的多元分析，开发了一种技术，可以对任何地层序列进行高分辨率的沉积学描述。不同测井曲线的数量及其范围允许确定岩石的许多物理特性。通过引入电相的概念，扩展了岩相的定义，电相是根据任何深度段的所有测井数据构建的。每个测井基准面都被认为是一个描述符，用于在测井层段中建立电相。一旦建立，如果已取心测井层段，则可以将测井相与实际地质相关联。参考文献23篇。
A technique has been developed using multivariate analysis of logging data to give a high-resolution sedimentological description of any sequence of formations. The number of different logs and their range allow determination of many of the physical characteristics of the rock. The definition of a lithofacies has been extended by introducing the concept of an electrofacies, constructed on the basis of all the logging data at any depth interval. Each logging datum is considered a descriptor for purposes of establishing electrofacies in a logged interval. Once established, electrofacies then can be correlated with actual geologic facies, if the logged interval has been cored. 23 refs.
