Abstract
The invention provides a sewage filter cleaning agent. The cleaning agent is used in oil fields to remove crude oil and impurities deposited on filter screens. The cleaning agent comprises the following components in weight percentage: a. 5 to 10 percent of citric acid; b. 3 to 5 percent of hydrochloric acid; c. 0.05 to 0.2 percent of hydroxide radical-1, 1-ethidene diphosphonic acid sulfonic acid; d. 4 to 6 percent of alkyl phenol polyoxyethylene(14) ether; and d. the remaining being water. The cleaning agent has the advantages that the cleaning agent can remove the majority of crude oil and impurities deposited on filter materials, and the filtering efficiency of the sewage filter which is cleaned is improved by 20 percent, the oil content of the sewage which is filtered is less than 4mg/l, and the oil content of the mechanical impurity is less than 10mg/l.
Description
Technical field
The present invention relates to the oilfield chemical technology field, particularly a kind of sewage filter cleaning agent is a kind of strainer back flushing that is used for, and removes the crude oil and the impurity that are deposited on the filter screen, makes the filter screen cleaning, the clean-out system that the sewage quality that filters out is up to standard.
Background technology
Oil-field development enters the middle and later periods, separates large amount of sewage from crude oil, and after sewage need reach the re-injection standard through processing, the additional producing energy in stratum was gone in re-injection again.In the process of oilfield treatments sewage,, need regularly strainer to be carried out back flushing for improving filtration efficiency.But at present backwash filter is used remains sewage, and backwash effect is undesirable.The strainer that cleaned still is stained with substantial oil, causes filtration efficiency low, and the sewage quality after the filter can not reach the water filling standard-required.
Summary of the invention
The objective of the invention is: a kind of sewage filter cleaning agent and preparation method thereof is provided, be exclusively used in and remove crude oil and the mechanical impurity that is deposited on the filter screen, thereby make the cleaning filtration that cleaned, reduce adhering to crude oil, improve filtration efficiency, make filtering sewage can reach the re-injection standard.
