Methods of integrating analysis, auto-sealing, and swellable-packer elements for a reliable annular seal |
摘要 |
A method of cementing involves introducing a pipe string into a well bore such that an annulus is defined between the pipe string and a wall of the well bore, and introducing a cement composition into the annulus. The cement composition includes cement, water, and an auto-sealing component. An annular structure, coupled to the pipe string, comprises an expandable material. |
