Description
Technical Field
The invention relates to the technical field of oilfield sewage treatment, in particular to a cleaning agent and a preparation method and application thereof.
Background
In the process of exploration and development of oil fields, high-pressure water is generally injected into a stratum to perform displacement so as to extract crude oil from an oil well, and after a period of water injection, the injected water is extracted along with the crude oil. In order to obtain qualified oil and gas products, water is required to be separated from oil and gas, and the separated water is called oily sewage. The sewage contains crude oil, metal ions and other impurities which pollute the environment, so the sewage can be discharged or recycled after being purified.
At present, the filtration method is one of the most main purification treatment methods for oily sewage, and the filter material in the filter can be used for removing particle impurities and crude oil in the oily sewage, so that the oil and water are separated, and the purpose of purification is achieved. In the process of filtering treatment, crude oil and suspended matters in the oily sewage are retained, and meanwhile, adsorption is formed on the filter material until hardening is formed, and the hardening of the surface of the filter material is further aggravated by deposition of metal ions, particularly calcium and magnesium ions, in the sewage, so that the filtering efficiency of the filter material is seriously reduced.
In order to solve the problems of impurities adsorbed on the surface of the filter material and hardening of the filter material, the filter needs to be cleaned regularly, generally, the filter material is cleaned through water backwashing, and then the impurities and hardened blocks adsorbed on the surface of the filter material are cleaned. However, it is difficult to remove impurities and hardened lumps adsorbed on the surface of the filter material by water backwashing alone, so there are some related cleaning agent studies reported. The application number is CN200810117488.0, and the invention name is 'Sewage filter cleaning agent and preparation method thereof', which discloses a cleaning agent, comprising the following components: citric acid, hydrochloric acid, hydroxy-1, 1-ethylenediphosphonic acid sulfonic acid, alkylphenol polyoxyethylene (14) ether, and water, and it is reported that cleaning of crude oil and mechanical impurities deposited on the filter material of the filter can be achieved by a backwashing method.
Although the existing cleaning agent can remove crude oil and mechanical impurities deposited on the surface of the filter material, metal ions and crude oil adsorbed on the surface of the filter material are not cleaned, so that the filtering efficiency of the filter material is still seriously reduced.

wherein the nonionic surfactant is selected from fluorine modified polyoxyethylene alcohol ethers.
According to the cleaning agent provided by the invention, the fluorine-modified polyoxyethylene alcohol ether, the chelating agent, the organic acid, the auxiliary agent and the water are reasonably configured, so that the components have synergistic effects, the obtained cleaning agent has a good cleaning effect on impurities such as crude oil, calcium ions and the like on the surface of a filter material, and the cleaning agent is particularly suitable for cleaning the filter material made of walnut shells and fiber balls. Therefore, the cleaning agent disclosed by the invention can not only remove the hardened lumps formed by the impurities and the filter material, but also remarkably reduce the residual quantity of the impurities adsorbed on the surface of the filter material, so that the higher filtering efficiency of the cleaning agent is still kept.
In the invention, the fluorine modified polyoxyethylene alcohol ether means that fluorine atoms partially or completely replace hydrogen atoms on carbon chains in the polyoxyethylene alcohol ether, and the addition of a proper amount of the fluorine modified polyoxyethylene alcohol ether can enable the obtained cleaning agent to have excellent emulsification and osmosis effects, so that the cleaning agent can quickly permeate into plate agglomerates to quickly disperse the plate agglomerates and separate the plate agglomerates from the surface of a filter material, thereby exposing impurities on the surface of the filter material and impurities in the plate agglomerates. And the cleaning agent has good cleaning effect through the synergistic effect with other components in the cleaning agent, and the residual quantity of impurities adsorbed on the surface of the filter material is remarkably reduced while the plate falling block is removed.

In addition, after the plate lumps are eliminated, the chelating agent can further react with metal ions deposited on the surface of the filter material, so that the residual quantity of impurities on the surface of the filter material is reduced.
In some embodiments of the invention, the chelating agent may be an organic acid sodium salt. In the specific implementation process of the invention, the organic acid sodium salt can be one or two selected from ethylenediamine tetraacetic acid sodium salt and nitrilotriacetic acid sodium salt.
Particularly, when the sodium ethylene diamine tetraacetate is selected from sodium ethylene diamine tetraacetate, disodium ethylene diamine tetraacetate and trisodium ethylene diamine tetraacetate, the cleaning effect of the cleaning agent can be obviously improved.
