摘要
储集层流动单元是一个横向和垂向上连续的储集带,它作为地下流体渗流的基本单元,综合反映了储集层的岩性、物性及微观孔喉特征。应用FZI(流动层段指标)将五2西克下组划分出四类流动单元,分流动单元建立了孔隙度和渗透率模型,并与未划分建立的解释模型进行对比,发现划分流动单元后建立的解释模型的精度更高。
Reservoir flow unit is a horizontal and vertical continuous reservoir zone. As a basic seepage unit of subsurface fluid, reservoir flow unit can synthetically reflect the characteristics of reservoir lithology, physical property and microscopic pore throat. By using flow zone indicator method(FZI), Kexia formation in Wu 2 Xi is divided into four types of flow units. According to these flow units, porosity and permeability models were established. Compared with the interpretation mode without dividing flow units, the interpretation model of flow units has higher precision
