The study of reservoir interbedded heterogeneity has always stayed on the concept model settled only on the core well analysis data.
储层内部成岩特征的差异或成岩非均质性可以通过识别成岩岩相、分析其垂向序列、编制成岩岩相图等得到合理描述。
Reservoir diagenetic features or diagenetic heterogeneties can be characterized by the recognizing diagenetic lithofacies, and their sequence analysis and mapping.
综合分析认为，引起储层非均质性的主要原因是沉积环境的变化。
