  Washed by 50 PV water, blocking rate over 85%. Water-plugging efficiency was 95.12%, oil-plugging efficiency was 20.45% and the breakthrough pressure of core was 112.2MPa/m, which can modify the water profile well.

  堵剂经50PV的水冲洗后,封堵率保持在85%以上,耐冲刷能力较强;堵水率为95.12%,堵油率为20.45%,具有较好的油水选择性;最大突破压力梯度为112.2MPa/m,封堵强度大,较好地改善了地层的吸水剖面。
