| Abstract: | This article introduces the liner cementation technology and its application in Wenchuan earthquake scientific drilling project. According to the conditions of complex formation in this drilling project, liner cementation technology which is suitable for broken formation and small annulus between borehole and casing string, has been developed. The key points of this technology include liner string design and installation and cementing slurry design and construction. This tech- nology has been successfully used in 4 liner cementation operations. |
