Abstract
The invention discloses a sterilizing corrosion inhibitor and a preparation method and application thereof. The sterilizing corrosion inhibitor comprises the following components in percentage by weight: 10-90% of a compound of formula (I), 10-90% of an organic polar solvent, 0-20% of an auxiliary agent and the balance of water;
Description
Technical Field
The invention relates to the field of petroleum and natural gas, in particular to a sterilization corrosion inhibitor and a preparation method and application thereof.
Background
In general, industrial water systems in the oil and gas field, and in particular industrial water in oil and gas field wells, have many different uses. Any water system, including its equipment and water, is susceptible to microbial contamination and scaling. Any metal surfaces in water systems are susceptible to corrosion, in part, due to microbial contamination and "microbiologically influenced corrosion". I.e. corrosion of the metal surface caused directly or indirectly by corrosion of the metal. And corrosion due to bacteria and their byproducts and metabolites on the metal surface, including in particular bacteria growing on the metal surface in biofilms. Bioerosion or bio-induced corrosion is typically associated with surface pitting, which results in faster corrosion damage than uniform corrosion.
Bioerosion or biologically induced chemical corrosion, typically caused by "sulfate-reducing bacteria" (sulfate-reducing bacteria SRB), is considered one of the major contributors to bioerosion under anaerobic conditions. It comprises a group of bacteria comprising at least 40 genus 137 species producing H 2 S, and bacteria using sulfate as terminal electron acceptor. Many SRBs are considered obligate anaerobes, meaning that they can temporarily tolerate low levels of oxygen, but in the presence of oxygen the cells are unable to normally metabolize and/or replicate. In addition, anaerobic conditions capable of supporting SRB growth can be created throughout the aerobic environment due to the microenvironment created within the bacterial biofilm/corrosion product layer. In addition, the bio-corrosion or bio-induced chemical corrosion also includes bio-corrosion or induced chemical corrosion of saprophytes, iron bacteria, and the like.
In general, SRB-induced bioerosion or SRB metabolization-induced H 2 S、CO 2 The chemical corrosion caused by the use of quaternary ammonium salts such as tetramethyl ammonium salt, tetraethyl ammonium salt, tetrapropyl ammonium salt, tetrabutyl ammonium salt, tetrahexyl ammonium salt and tetraoctyl ammonium salt is sterilized or controlled, but because the ammonium salt is cationic surfactant, a large amount of foam which is difficult to eliminate under the influence of air flow is generated with produced water during the use, and the foam not only can collect and transportThe process causes the influence of air resistance, and also can cause influence on production because the separator is incompletely separated.
Hydrogen sulfide and carbon dioxide are produced when organic matters are decomposed by bacteria in the process of forming petroleum and natural gas, are associated gas of petroleum and natural gas, and are faced with H in the development and production processes of many oil and gas fields at home and abroad 2 S/CO 2 Chemical corrosion and microbial corrosion present serious challenges for safe production.
At present, the filling of bactericides and corrosion inhibitors is a mainstream method for inhibiting corrosion and guaranteeing pipeline safety, wherein the bactericides are used for killing and controlling microorganisms, and the corrosion inhibitors mainly play a role in inhibiting electrochemical corrosion. Patent application CN106719681A discloses an oilfield sterilization corrosion inhibitor and a preparation method thereof, patent application CN110273157A discloses a corrosion inhibitor with sterilization and scale inhibition functions and a preparation method thereof, patent application CN104628097A discloses a composition for the sterilization corrosion inhibitor, and patent application CN109971447A discloses a sterilization corrosion inhibitor for oil well gathering and transportation and sewage treatment systems and a preparation method thereof. Patent application JP2006348079A discloses a diamine alkoxy compound which has bactericidal, low foaming and corrosion inhibiting properties. Patent application RU2255141C1 discloses a bactericidal corrosion inhibitor for oilfield hydrogen sulfide-mineralized aqueous media, which is prepared by reacting a C8-C18 primary fatty amine with a phosphorus-containing acid derivative, particularly a product of phosphoric acid and a polyol. Patent application RU2259393C2 discloses a bactericidal corrosion inhibitor of an industrial detergent composition with anti-corrosive and bactericidal properties, which is prepared by reacting N, N-methyl methane diamine with alkyl and alkenyl chlorides, and can be used in all industrial fields where metal surfaces are attached by organic oil stains including oil gas, lubricating oil, latex contents, asphalt, tar, paraffin and the like. Patent application US9802908B2 discloses that an ethylbenzyl quaternary ammonium salt of amino amide has bactericidal performance and can be used as an oil field cleaning soap clay cleaning agent and a corrosion inhibitor. The techniques can play a certain role in sterilization and corrosion inhibition.
However, the prior art suffers from at least the following problems: 1) Most of the existing bactericidal corrosion inhibitor products are compositions, namely, the corrosion inhibitor is mixed with the bactericide. The product performance is difficult to be improved on the basis of the original corrosion inhibitor and bactericide. 2) Most of the existing sterilizing corrosion inhibitors sold in the market and most applied are based on quaternary ammonium salt, wherein the quaternary ammonium salt is a cationic surfactant, and a large amount of foam which is difficult to eliminate can be generated with produced water under the influence of air flow in the use process, and the foam not only can cause air resistance influence on the gathering and transportation process, but also can cause influence on production because of incomplete separation of a separator.

In terms of sterilization mechanism, effective sterilization molecules generally comprise hydrophilic cationic groups and hydrophobic alkyl chains, the mechanism is mainly that antibacterial polymers are firstly adhered to the surface of bacteria through electrostatic interaction, then substituted alkyl groups on the molecules penetrate cell membranes through hydrophobic interaction to cause bacterial death, and therefore, the effective high-molecular bactericide should comprise three elements: (1) must be in sufficient contact with the cells; (2) sufficient cationic charge must be present to promote adhesion to the microbial cell membrane; (3) a portion of the hydrophobic chains must be available to adsorb and fuse into the porous cell membrane interior. Because the surface of the bacterial cell membrane is negatively charged, the compound shown in the formula (I) is an ionic compound with positive charges, and can be adsorbed on the surface of the bacterial cell membrane through electrostatic interaction, and the hydrophobic group part of the compound penetrates through the cell membrane to enter the cell interior to play a role in sterilization. The imidazole derivative is a broad-spectrum bactericide, but because of poor water solubility and poor practical application, 2-undecylimidazole has weak alkalinity and can react with organic acid to generate ionic compounds with positive charges, the water solubility of the ionic compounds is enhanced, the ionic compounds play a role in adsorbing and sterilizing, and in addition, S, P in the organic acid can enhance the performance in corrosion inhibition.
