辽东湾地区古近系储层质量分析

通过对大量物性数据的分析与整理，结合薄片鉴定和扫描电镜技术，重点对辽西凹陷、辽西低凸起、辽中凹陷几个地区在层序地层格架内进行储层质量分析。结合辽东湾地区的各种沉积环境，分析储层物性的控制因素，认为物源控制储层的岩石类型；沉积相带控制储集体的展布；成岩作用控制储层物性的好坏。根据碎屑岩储层的评价标准，对辽东湾地区不同层序做出储层评价及预测。依据层序格架、沉积类型和成岩作用综合研究，指出东二段储层的物性好于古近系其他层序的储层物性，辽西低凸起东二段物性较辽西凹陷和辽中凹陷的要好。

Analysis on Reservoir Quality in Paleogene of Liaodong Bay

By analyzing a great quantity of laboratory data, this paper studied the reservoir quality of Liaoxi low-uplift and Liaozhong Depression and Liaoxi Depression .The methods of studies involve stratigraphic analysis and core sample analysis. Thin-section observation is applied to study the main problem. The reservoir quality in different sequence is obvious different. The favorable and high quality reservoir is forecasted according to the results of sequence framework, sedimentary facies and diagenesis of Pal...
