宝浪油田储集层的岩石,在仅有束缚水而无自由水的条件下,油相渗流需要一个较高的启动压力梯度;油藏相对渗透率曲线形态类型较多,以直线为主;一般相对渗透率曲线具有束缚水饱和度较高、残余油饱和度较低以及残余油状态相对渗透率较高、两相流动区间较宽的特点;孔喉组合模式以及注入水质,对相对渗透率曲线有重要影响。
The rock of reservoir reservoirs in Baolang oilfield need a higher starting pressure gradient under the condition of only irreducible water and no free water. The relative permeability curves of reservoirs have many morphological types and are dominated by straight lines. The general relative permeability curve has the characteristics of higher irreducible water saturation, lower residual oil saturation, higher residual oil relative permeability and wider two-phase flow interval. The combination of pore-throat and injection water quality has a significant effect on relative permeability Curves have important implications.
