Abstract

Un cemento para uso en pozos donde está presente sulfuro de hidrógeno que comprende partículas de elastómero. En el caso de falla de la matriz de cemento o falla de enlace entre la interfaz de cemento/revestimiento o la interfaz de cemento/pared de pozo de sondeo, las partículas de elastómero se dilatan cuando entran en contacto con sulfuro de hidrógeno. La dilatación sella huecos en la matriz de cemento o a lo largo de las interfaces de enlace, restableciendo así el aislamiento zonal.A cement for use in wells where hydrogen sulfide is present comprising elastomer particles. In the case of cement matrix failure or link failure between the cement / cladding interface or the cement / borehole interface, the elastomer particles expand when they come into contact with hydrogen sulphide. The expansion seals gaps in the cement matrix or along the link interfaces, thus restoring the zonal isolation.
