| Abstract: | At present, the casing failure problem is common in some old oil fields in China, and it has a serious impact on stable production of the oil fields. In this paper, in order to redevelop and utilize the casing failure wells, research and application of the cementing technology with small diameter expansion tube were carried out. The process adopted ~ 107.95/116.72 mm expansion tube to implement side tracking for the old wells, and used fine cementing process to ensure cementing quality, production of the old wells rose significantly after the side tracking. The practice result has proved that the process has good use effect and economic benefits. |
