| 摘 要： | 油水相对渗透率可以精确刻划出油、水二相流体在孔喉中的流动情况,通过阿尔奇方程准确求取储层的含水饱和度,建立适合镇泾油田的束缚水饱和度计算模型,并运用"岩心刻度测井"的方法,通过回归法,用实测油、水相对渗透率曲线求取琼斯方程中的区域参数,最终建立适合本区的油水相对渗透率经验公式。结果表明,用测井数据可以进行油、水相对渗透率的计算,并且完全满足评价储集层的产液情况。由此建立的油水相对渗透率解释模型,可以进行镇泾油田长6储层的油、水层的划分,并对油、水分异不彻底的储层进行测井评价,有着重要的参考价值。

| Abstract: | Produced fluid types can be depicted precisely by relative permeability in pore throat.First,we should get water saturation accurately by Archie equation and build calculating model of irreducible water saturation adapting to Zhenjing oil field,then get area parameter of Jones equation from experimental oil and water relative permeability curves by calibrating well logging to the cores,build relative permeability experienced equation adapting to this field.It is showed that well logging data can be used to calculate oil and water relative permeability that can satisfy produced fluid types of evaluating reservoir.The oil and water relative permeability model built by the above methods can classifies oil and water layers,and are of important reference values for reservoir well logging evaluation in which the separation of oil and water is poor. |
