摘　　要：以取心井岩心分析资料为基础,优选出流动层带指标、孔隙度、渗透率、泥质含量、粒度中值等参数,采用灰色系统理论,有效地定量判别流动单元。将克拉玛依油田八区克上组砂砾岩划分出4类流动单元,这4类流动单元与剩余油分布关系较为密切,流动单元Ⅰ水淹严重,流动单元Ⅳ、Ⅴ区为低孔、低渗,原始含油性本身较差,而流动单元Ⅱ、Ⅲ是该区油藏下一步挖潜的主要目标。Based on core analysis data from coring wells, the indexes, porosity, permeability, grain-size median are selected for the flow zones. Theory of grey system is used to effectively identify the flow unit. The conglomerate reservoirs in Keshang Formation in Region 8 of Karamay Oilfield are divided into 4 units, these units are closely related with remaining oil distribution, where flow unit 1 is watered out severely, units Ⅳ and Ⅴ are low porosity and low permeability reservoirs with poor oil-bearing property, while units Ⅱ and Ⅲ are the main target zones for tapping the potential in the area.
