| 摘 要： | 在测井二次解释和地层精细对比的基础上,本文建立了岩芯-测井相模式并编制了单砂层平面沉积微相图。依据孔隙度、渗透率和有效厚度参数,采用H·K/φ作为主控物因数划分出了Ⅰ、Ⅱ、Ⅲ和Ⅳ共4类流动单元并以"相控"法确定了平面流动单元类型分布。流动单元Ⅰ和Ⅱ类为高效渗流单元,即水淹单元,Ⅲ和Ⅳ类流动单元为低效渗流单元,即潜在剩余油存在单元,并由此确定了河间和河道内部剩余油分布区,为油田高含水阶段利用常规资料精细分析剩余油分布提供了新思路。

| Abstract: | On the basis of secondary log interpretation and stratigraphic correlation,this study established core-logging facies model and mapped planar sedimentary microfacies of single sand layer. According to porosity,permeability and effective thickness parameters,and using H·K/φ as the main controlled parameter,four flow units(Ⅰ,Ⅱ,Ⅲ and Ⅳ)were identified and their planar distributions were mapped by "Facies Control". Types ⅠandⅡ are efficient flow units,i.e. water-flooded units,whereas types Ⅲ and Ⅳ are inefficient flow units,i.e. potential remaining oil occurrence units. Based on flow units,remaining oil distribution area in channel and interchannel is determined. From this study,a new method is provided by accurate conventional data analysis of remaining oil distribution on high water cut stage of oil field. |
