Flexible cementing compositions and methods for high-temperature wells |
摘要 |
A well cementing composition comprises an hydraulic cement and flexible, acrylonitrile-butadiene copolymer particulate material. A method of cementing a well comprises mixing the composition with sufficient water, and optionally, other additives to form a pumpable slurry, and pumping the slurry into the well and allowing it to set.
