结合油田测井地层对比的实践,阐述了利用测井地层学进行等时地层划分与对比的原理和方法;概括了组合特征、相对稳定的和易变的特征、完整地层序列等测井地层学内涵;总结了地层划分对比的4个关键步骤：区分相对稳定的和易变的测井特征;建立完整地层序列;分区建立标准剖面;分区展开进行地层划分对比.

By combined with the practice of oil field logging stratigraphic, the principal and method of special logging-stratigraphy are described. Some logging stratigraphic connotations are generalized, including the characteristics of combinations, the characteristics of relative stability and easy change, and complete stratigraphic sequence, etc. The four key steps of stratigraphic division and correlation are also summarized as follows:(1) distinguishing the logging characteristics of relative stability and easy-changed formations; (2) establishing a complete stratigraphic sequence; (3) developing the standard section in areas; (4) dividing formations in areas and contrasting the formations. The logging stratigraphic correlation is refined by using the method; and it is not only promoting the prosperity of the stratigraphy research, but also beneficial to the production and research work of oilfield.
