| titleOfInvention | HIGH ANTI-CORROSIVE PROTECTION MILK FOR THE CEMENTATION OF HYDROCARBON PRODUCTION WELLS OR WATER INJECTION WELLS AND PROCEDURE FOR CEMENTING THE WELLS USING SUCH MILK |
| abstract | High corrosion protection grout for cementing hydrocarbon production wells or water injection wells, which is used under extreme conditions of temperature and pressure, and procedure for cementing the wells using said slurry. The slurry is a typical slurry further comprising at least one inorganic corrosion inhibitor in a proportion between 0.5 and 4% by weight with respect to the weight of the cement, preferably said inhibiting agent is sodium nitrite, calcium nitrite or a combination thereof. The slurry herein may further comprise other additives such as relievers, dispersants, filter reducers, accelerators and retarders of frague, latex or combinations thereof. Methods for cementing hydrocarbon producing wells or water injection wells are also described, wherein the cement slurry is prepared by adding an inorganic anticorrosive agent such as sodium nitrite to the slurry or mixing them with the remaining dry compounds prior to the addition of water. |
