| 摘 要： | 利用密闭取心资料对相对渗透率实验得到的分流量关系曲线进行校正,得到油藏条件下的分流量曲线,通过对油藏条件下的分流量曲线进行内插,建立油水同层初期含水率解释图版.油水同层初期含水率解释图版可以根据储层空气渗透率和原始含油饱和度查得储层初期含水率,从而界定开发井射孔井段、预测单井产能等.利用葡西试验区11口井单层射孔资料验证,该方法解释符合率为82%. |

| Abstract: | Fractional flow relationship curve obtained from relative permeability test by using sealed coring data are adjusted, so fractional flow curve under reservoir condition is obtained. Through interpolation of fractional flow curve in reservoir condition, initial water cut interpretation chart of oil/water same layer is established. It can determine initial water cut based on reservoir air permeability and primary saturation, thereby determining perforated interval development well and predicting single well production. Coincidence rate of this method is 82% by certification based on single layer perforation data of 11 wells in the west of Putaohua test area. |
| Keywords: | west of Putaohua Oilfield initial water cut in reservoir low-permeable oil/water same layer relative permeability |
