摘要
针对中原油田油水井套管损坏严重,常规大修修套工艺难以修复套管长距离多处损坏的油水井,应用了φ101.6无接箍套管、套管扶正器,并应用了延迟固井工艺,确保了φ101.6套管间的固井质量,取得了良好的技术经济效益。
In the light of the serious casing failure problems in oil/gas well of Zhongyuan Oilfield, the conventional workover technology can't repair long distance damaged casing in the deep well .So, the research of 101.6 casing delayed cementing technology was carried out. This technique applied 101.6 extreme-line casing, casing centralizer and delayed cementing technology to ensure the cementing quality between 139.5 and 101.6 casing. The field application had obtained good economic benefit.
