【摘要】 针对水驱油藏油水两相的情况,论述了以生产测井资料为基础、结合裸眼井测并资料确定产层剩余油饱和度的方法.该方法的特点是,根据产水率与油水相对渗透率、含水饱和度三者之间存在的密切关系,建立以油水相对渗透率比值为桥梁的剩余油饱和度解释模型;采用回归分析方法建立一系列的计算关系式.对现场实际测量资料进行了处理,结果表明,该方法确定的剩余油饱和度与常规测井解释结果具有良好的一致性.更多还原

【Abstract】 For water- drive reservoirs with oil and water fluids,a method is presented to determine remaining oil saturation of production beds by combining production logging and openhole logging data. The characteristic of this method is that, the ratio of oil relative permeability to water relative permeability is used as a bridge to develop an interpretation model of remaining oil saturation, according to the relationship between oil/water relative permeability and water cut and water saturation 0 And some regression equations are obtained by regression analysis0 The method is examined with well logging measurements from an oil field 0 The result shows that remaining oil saturation obtained from this method is well agreed with that from conventional log interpretation.更多还原
