高分辨率层序地层学在储层宏观非均质性研究中的应用——以松辽盆地朝阳沟油田朝1—朝气3区块扶余油层为例

运用高分辨率层序地层学原理和方法，在朝阳沟油田朝1—朝气3区块扶余油层识别出41个短期、7个中期基准面旋回及2个长期基准面半旋回。通过不同级次基准面旋回成因的沉积动力学分析和表征储层宏观非均质性的各项岩心化验、统计学数据定量分析，指出随着长期基准面的上升，各短期基准面旋回层内非均质性变强、各中期基准面旋回层间非均质性变弱、各短期基准面旋回平面非均质变强；随着长期基准面的下降，各变化趋势正好相反。指出基准面旋回及其伴随的可容纳空间变化所引起的沉积环境的变化是储层宏观非均质特征差异的决定因素。

Application of High-Resolution Sequence Stratigraphy in the Study of the Reservoir Macro-heterogeneity:Taking the Fuyu oil layer of Chao 1-Chaoqi 3 blocks in Chaoyanggou oil reservoir of Songliao Basin as an example

In application to high-resolution sequence stratigraphy principles and methods,forty one short-term base-level cycles and seven middle-term base-level cycles and two long-term base-level semi-cycles in Fuyu oil layer of Chao 1 Chao gas 3 blocks of Chaoyanggou oil field are identified.By the sedimentary dynamics analysis of genesis of multiage base-level cycles,quantitative analysis of the core testing and statistical data which characterize the macroscopic heterogeneity of the reservoir,we point out that wi...
