摘要
在多层射孔井段化学堵水时采取笼统挤注工艺，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。本文针对化学堵水气举井（LN2—3—16）的具体特点，着重介绍解除堵塞释放油层的方法及现场实例。
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 harm to the oil formation, Focus on the characteristics of a chemical water shutoff and gas-lift well(LN2-3-16),this article intorduces the method and application sample of plugging breaking for oil formation release.
