摘　　要：针对底水油藏水平井开发过程中,底水一旦锥进入井筒,造成含水迅速上升甚至水淹的问题,通过在完井阶段充填改性疏水陶粒,抑制底水在水平井井筒轴向窜流,延缓油井含水上升速度;对改性疏水陶粒控水机理进行了分析,通过模拟完井充填过程,评价了合成的改性疏水陶粒的选择性阻水性能,室内评价及现场试验均表明改性疏水陶粒具有较好的控水效果。In view of the horizontal wells in bottom water reservoir development process,once the bottom water come into the wellbore,water cut rising rapidly even water problem,through the completion stage filling modification of hydrophobic ceramsite,inhibition of bottom water in horizontal wellbore axial flow,slow water cut rising velocity.Hydrophobic modified ceramsite water control mechanism is analyzed,by simulating completion filling process,the evaluation of the synthesis of modified hydrophobic selectivity of ceramsite block water performance,evaluation of the indoor and field test showed that hydrophobic modified ceramsite has good effect of water control.
