摘要： 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。

Abstract: The percolation to oil in reservoir rock of Baolang oilfield couldn't start with till a relatively high pressure gradient was formed in it, in the case o{ existence of inreducible water only(no free water). It shows Imnany shapes of relative permeability curves, in which the straight line is comrron. In general, these curves are characterized bv high ineducilhle water saluratiol, low remaiming oil saturation with high relative perimeability and wider two-phase region. It is also shown tlrat the fects of pore-throat combilnation patterns and injected water quality on the relalive penmeability ('urves are (o11sirable.
