| 摘要: |
| 在多层射孔井段化学堵水时采取笼统提注工艺，当原始油水界面抬高后，油层见水，堵剂不仅在水层成胶，在油层也成胶，因而对油层造成很大的损害。本文针对化学堵水举井（ＬＮ２－３－１６）的具体特点，着重介绍了解除堵释放油层的方法及现场实例。 |

| Abstract: |
| The general squeezing technical process is adopte for chemical water shutoff in multiple perforated zones.When the boundary layer of water-oil rises, water goes into the oil layer and causes gel colloid both in water layer and in oil layer, which make har |
