During the completion well testing period of the vertical well section of Ku 1, we tested 2 times and the downhole packer was all imbedded, result in very serious downhole accident.
库1井直井段在完井测试期间, 2次测试井下封隔器均被埋死,造成非常严重的井下事故。
This classification would be useful to qualitatively design of horizontal well, selection of the completion method and treatment methodology of horizontal wells in late period.
可为水平井新井设计、完井方式选择、后期措施工艺选井等提供参考依据。
