Resumen:
The geological storage of carbon dioxide (CO2) can become a solution to limit the effects of greenhouse gases if the integrity of long-term storage is ensured. The different types of geological storage (Aquariums, abandoned reservoirs, saline cavities, veins of coal) require cemented injection wells. The hardened cement paste is in contact with the rock formation (Reservoir and cover) and the fluids of the geological formation and the injected gases. The interface rock-cement will be submitted throughout the injection process and to the accumulation of the injected gas (CO2) in is useful life. In the region of the injection well, the system rock-cement is a critical point to ensure long-term integrity of this type of storage to prevent the escape of injected gases to higher aquifers.In view of this problem, this article studies through the use of polymers and nanotechnology, the critical alteration matrix of the rock-cement interface at the level of the reservoir rock cover and the cementing of the injection well contact and the consequence of its degradation in a storage context of CO2.
