| 摘 要： | 研究了胜油田的油藏岩石用大量水冲刷前后岩石渗透率、毛细管压力及油水相对渗透率曲线的变化。试验结果表明，岩石水洗前后气体渗透率增加、孔隙半径增大的居多；气体渗透率减小、平均孔隙半径减小者也有之，另外还有气体渗透率、平均孔隙半径变化不大的情况。总之，油水相对渗透率变化情况比较复杂。

| Abstract: | The changes of permeability,capillary pressure curve and relative permeability curve of flooding sandstone in Shengtuo oilfield are studied. The result shows that the permeability and macropore ratio in flooding sandstone increase greatly. and the permeability and mean pore size in flooding sandstone decrease.The change of relative permeability curve is complex. |
