| titleOfInvention |
foaming composition with wetting capacity modification and corrosion inhibiting properties for high temperatures and ultra-high salinity conditions, and use of foaming compositions with wetting capacity modification and corrosion inhibiting properties |
| abstract |
The present invention relates to the obtainment and use of foaming compositions with wetting capacity modifying and corrosion inhibiting properties at high temperatures and ultra-high salinity in naturally fractured carbonate reservoirs, they favorably alter the wetting capacity of the rock in intensified crude oil recovery processes and control the uniform corrosion problems that occur in production equipment under conditions of high temperature and ultra-high salinity; through the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultains or alkyl hydroxysultains with sodium alkyl hydroxysulphonates and sodium alkenyl sulphonates (1). the foaming compositions with wetting capacity modification and corrosion inhibiting properties are characterized by being tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and by the fact that for their application in the reservoir, sea water and/or the congenital water characteristic of the reservoir can be used as a means of transport. |
