FOAMING COMPOSITION WITH WETTABILITY MODIFYING AND CORROSION INHIBITORY PROPERTIES FOR HIGH TEMPERATURE AND ULTRA-HIGH SALINITY

摘要

The present invention relates to a method of obtaining and using foaming compositions with wettability-modifying and corrosion inhibitory properties that control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions by the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir.

1. A foaming composition with wettability-modifying and corrosion inhibitory properties at high temperature and ultra-high salinity conditions, comprising a supramolecular complex as active component resulting from the interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates.
