HIGH TEMPERATURE WELL CEMENT COMPOSITIONS AND METHODS |
摘要 |
Improved set retarded cement compositions and methods of using such compositions which are substantially non-thinning at high temperatures and which can include fresh or salt water are provided. The compositions are comprised of hydraulic cement, sufficient water to form a pumpable slurry, a set retarder and a delayed viscosifying agent which yields viscosity at high temperatures comprised of a treated depolymerized galactomannan gum.
