克拉玛依油田八区克上组砾岩油藏流动单元研究

Study of Flow Element of Conglomerate Reservoir in Upper Karamay Formation,District 8 in Karamay Oilfield.

针对克拉玛依油田八区克上组砾岩油藏储集层特征,分析了流动单元研究的基本思想和原理,依据相应的聚类分析方法,结合克上组储集层岩性、物性及其微观孔隙结构特征,研究了该区砾岩油藏流动单元类型、特征及流动层带指标(IFZ)的划分界限和计算方法,对该区砾岩油藏各小层流动单元进行了划分和描述。分析和阐明了不同级别流动单元分布、特点与砾岩油藏沉积微相、隔夹层及储集层质量的关系,指出了不同层位砾岩油藏储集层质量及分布富集区域。

This paper analyzed the basic ideas and principle for flow element study in light of the characteristics of conglomerate reservoir in Upper Karamay formation of District8,Karamay oilfield,studied types and features of the flow element,delineation and computed methods of flowing zone index(I FZ ),based on corresponding cluster analysis inte-grated with Upper Karamay reservoir lithology,petrophysical property and microscopic pore structural features,and classified and described the individual small flow element in this conglomerate reservoir.Furthermore,the distribution and characteristics of different ranking flow elements and their relations to depositional microfacies,barriers and in-terbeds as well as reservoir quality were analyzed and explained,providing the qualities of conglomerate reservoirs in different horizons and distributed or enriched areas.
