A composition for Dissolving Calcium Carbonate and magnesium, calcium sulfate, Iron oxides, sulfides and metal fouling related Operations, in acidizing of injection Wells and other in Secondary Oil Recovery

摘要

The composition is especially suitable to be applied in Operations and also dissolution of calcareous deposits in the clearance of Industrial piping, Heat exchangers, boilers and Steam Generators, as well as Operations inyectore acid Stimulation of Wells S of water, and in transactions related to the secondary Recovery of OilIts function is to dissolve deposits of insoluble salts of calcium, Magnesium, Strontium and Barium, providing Corrosion Protection for metals exposed and avoiding the re precipitation of dissolved salts, to a change in pH, supersaturation, by Contamination with Salm Ueras.Includes the use of fosfonoderivados (such as urea, corrosion retardant acid), to prevent redeposition of salts of calcium, Magnesium, Strontium and Barium (for dilution or acid consumption, Raising the pH), in conjunction with urea adducts and inorganic acids, tale S as hydrochloride, urea, mono and di urea sulfate, phosphate, and nitrate.The Development of inorganic acids with urea adducts, May understand hidrocloruros mono and di urea, sulfates, Phosphates and Nitrates, CHLORIDES, in conjunction with ureic phosphonate Derivatives.Also, the urea derived phosphonate,May be a ATMP (trimethylen amino acid phosphonic acid (HEDP); a hidroxietilen difosfu00f3nico (dtpmp); a dietilentriamino Pentametilen phosphonic acid); a hempa (hexametilendiamino tertametilen phosphonic acid (PBTC); or a fu00f3sfono tricarboxu00edlico acid butane); or a hdtmp ( Hexamethylenediamine tetrametilen phosphonic acid (EDTMP); or a phosphonic acid tetrametilen: ethylenediamine).
