尚店油田东部沙四段储层非均质性研究

Reservoir Heterogeneity Study of the Fourth Member of Shahejie Formation in East Part of ShangDian Oilfield

综合利用岩心观察、粒度分析、岩石薄片鉴定、扫描电镜分析及测井资料综合解释成果,对尚店油田东部沙四段储层非均质性进行了系统研究。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。在此基础上建立了滨浅湖沉积环境下不同沉积微相的储层非均质性模式,为油田开发方案的编制和调整打下基础。

Reservoir heterogeneity of the Fourth member of Shahejie Formation was studied by using log data and digital pressing achievement, size analyses, cast sections and SEM By analyses, the main reason of poor reservoir heterogeneity is the change of depositional environment, On this base we build a mode of reservoir heterogeneity of Shore-lake and Shallow-lake sul-facies. The results is helpful to the research of reservoir and adjusting production of oilfield development.
