Definitions
- the present invention belongs to the field of corrosion inhibitors and to the methods for inhibiting corrosion m pipes, pumps and other metallic materials that can be in contact with highly acidic solutions used in the stimulation of oil wells and the like.
- Hydrocarbons (petroleum, natural gas, etc) are obtained from an underground geological formation (in other words, a deposit) by drilling a well that penetrates the geological formation containing said hydrocarbons.
- a deposit is an underground rocky body that is sufficiently porous and permeable to store and transmit fluids.
- the recovery of hydrocarbons varies due to factors related to the heterogeneity of the deposit (type of rocky body forming it), the type of fluid produced, the drainage mechanisms, etc.
- Hydrocarbon producers normally carry out stimulation techniques with acid to increase the overall permeability of the deposit, creating conducting routes from the deposit to the well and passing through the area surrounding the well which has been damaged during the drilling and foundation .
- the stimulation techniques include: (1) injecting chemical products into the well to react with and to dissolve the area surrounding the well which has been damaged; (2) injecting chemical products through the well and into the geological formation to react with and to dissolve small portions of rock to create small conducting channels (conducting wormholes) through which the hydrocarbon will flow (so that rather than eliminating the damaged areas, the hydrocarbon is re-directed through said areas);
- acids or acid-based liquids are used for this purpose due to their ability to dissolve minerals and pollutants introduced in the well during drilling or recovery operations.
- the most common agents used in well stimulation with acids are mineral acids such as hydrochloric (HCl) and/or hydrofluoric acid (HF), generally in the form of 15% by weight acid solutions.
- a problem inherent to stimulation with acids is the corrosion of the pump equipment and of the pipes of the well caused by contact with the acid, although the petroleum and natural gas or the water entrained therewith also contain corrosive components, for example, CO 2 or H 2 S and salts, leading to severe corrosion of the metallic surfaces. Furthermore, the working liquids used in this field, for example, the sludge for the sweeping of the drillings, contribute to corrosion.
- the so-called corrosion inhibitors are used for protection against corrosion, and are added to the liquids which come into contact with metallic surfaces. Corrosion inhibitors either form a film on the metallic surface or reduce the corrosion process by means of physical and chemical reactions on metallic surfaces.
- Additives for very acidic solutions which, on one hand, are not only effective as corrosion inhibitors but also do not increase the environmental risks of the process, have been sought for some time.
- Innumerable compositions containing amines, quaternary ammonium compounds, acetylene alcohols and/or ethoxylated phenol type surfactants are described in the state of the art. Said compounds are considered to be to be hazardous for the environment.
- patent US-A-3589860 describes the use of cinnamaldehyde or derivatives thereof as a corrosion inhibitor for equipment used in chemical processes and for petroleum extraction equipment in contact with acid media.
- Patent US-A-4734259 describes a composition and a method for inhibiting corrosive aqueous fluid attack on metals by means of a composition including an ⁇ , ⁇ - unsaturated aldehyde and a surfactant. Cinnamaldehyde and derivatives thereof are included among the preferred ⁇ , ⁇ - unsaturated aldehydes. Alkylaryl sulphonates, quaternary ammonium compounds and alkyl and alkylaryl polyether alcohols are among the preferred surfactants.
- Patent US-A-5120471 describes a composition for inhibiting steel corrosion containing more than 9% of chromium in the presence of at least one mineral acid, said composition comprising: a) an organic inhibitor selected from the group consisting of phenylacetone, phenylacetone with a quaternary ammonium salt of a heterocyclic aromatic compound, and cinnamaldehyde with a quaternary ammonium salt of a heterocyclic aromatic compound; and b) a compound soluble in acid of antimony or bismuth type.
- Patent US-A-5854180 describes a composition for inhibiting corrosion caused by hydrochloride acid solutions used for acidifying petroleum wells, in which said composition comprises a) 10-30% by weight of cinnamaldehyde or substituted cinnamaldehyde; b) 20-50% by weight of ethylene glycol; c) 5-20% by weight of C 8 -Ci2 ethoxylated alcohols; d) 1-15% by weight of a composition containing 10-40% by weight of isopropanol and of a reaction product of a ketone with 3-9 carbon atoms, urea, thiourea or alkyl- substituted thiourea, benzaldehyde or formaldehyde and hydrochloric acid.

- water an aliphatic aldehyde with 1-10 carbon atoms
- aromatic aldehyde with 7-20 carbon atoms.
- Preferred aliphatic aldehydes are glyoxalic acid and glyoxal.
- a preferred aromatic aldehyde is cinnamaldehyde.
- compositions from the state of the art have reached a certain degree of effectiveness against corrosion, they are questionable from an environmental point of view in some cases.
- cinnamaldehyde and/or substituted cinnamaldehyde are quite expensive, it is necessary to develop corrosion inhibitors for acids that provide an efficient technical performance that overcome the environmental and financial drawbacks set forth.
- cinnamaldehyde and/or substituted cinnamaldehyde with urea provides a corrosion inhibiting composition reducing the attack of several aqueous fluids, such as aqueous acids, against ferrous metals, such as iron and steel, as well as against non- ferrous metals, such as aluminium, zinc and copper.
