FEATURES OF FLOW UNITS AND THEIR GENETIC CLASSIFICATION
-
摘要: 该文将流动单元定义为具有相同渗流特征的同一储层单元,并认为流动单元具有相对性、层次性和规模性。在分析了流动单元的基本特征后,提出了流动单元的成因分类方案,把流动单元划分为受断层、隔层、夹层、渗透率韵律、层理构造、裂缝及孔隙结构控制的7类流动单元。不同成因的流动单元,反映了储集层非均质性的规模性和层次性,其研究内容和方法不同。Abstract: The flow unit is defined as the same reservoir unit with identical seepage features, and it is considered that the flow unit is relative and in some level and scale. After analysing the basic features of flow units, a genetic classification scheme of flow units was suggested. Flow units were classified as seven types controlled by faults, impermeable strata, intercalated bads, permeability rhythm, stratification tectonics, fissures and pore structure, respectively. The flow unit of different genesis reflects the scale and level of reservoir heterogeneity and has different studying contents and methods.
