| 摘 要： | 胜利油田草古１潜山稠油油藏缝洞十分发育，导致固井过程中水泥浆严重漏失。本文在分析该油藏地质特征、油藏类型的基础上，改进了固井技术，采用封隔器—分级箍和水泥伞—分级箍的固井工艺很好地解决了该油藏漏失井固井问题，在４５口井的应用中，固井合格率１００％，优质率８９％。

| Abstract: | In casing cementing of Caogu 1 Qianshan reservior, lost circulation is encountered due to growing cracked holes. The analyses of reservior properties lead to improve cementing techniques which apply packerstaged collar and cementing basketstaged collar cementing methods, and lost circulation is controlled. Applications in 45 wells show that all cementings are qualified. |
