Description
Technical field
The invention belongs to oil field environment-protection technical fields, and in particular to a kind of sulphur removal-sterilization-inhibition one inorganic agent and its system
Preparation Method.
Background technique
There are a large amount of microorganisms in oil field, will cause the corrosion and damage of equipment, the blocking of pipeline and water injection well；Make oil reservoir
Void permeabilities decline, interferes water flood recovery；Even can degrade other oil field chemicals and weaken its medicament use effect
Rate, it is therefore desirable to launch fungicide to guarantee the progress of oilfield construction.
In the secondary oil recovery of oil field, a large amount of water is needed, for protection environment, Modern oil field returns after mostly using water flood treatment
The mode of note, since salinity general in reinjected water is all very high, part acid can remain in the earth formation, in oil field in part acidic liquid
The vital movement of microorganism can generate the part organic matter harmful to steel, reinjected water is dealt with improperly and will lead to water oxygen level
Rise, since subsurface temperature is higher, factors above all easily causes to corrode to Oilfield Water Injection Pipelines, will lead to oil field tubulars when serious
Line perforation.These all cause huge economic loss to oil field production run.Therefore, it is typically necessary and is added before produced-water reinjection
Corrosion inhibiting and descaling agent is pre-processed.
Sulfide is generally existing in oilfield sewage, and burn into proliferation of sulphate reducing bacteria and water is therefore brought to mention surely
The problems such as fixed difficult.Therefore, it generally requires that sulfur elimination progress sulphur removal is added in oilfield sewage.Often, oxidisability class desulfurization
Agent has preferable sulphur removal, antibacterial and corrosion inhibition, is frequently utilized for oilfield sewage sulphur removal.
But the above fungicide, corrosion inhibiter and desulfurizing agent be added itself oil field can be generated certain secondary pollution and
Toxicity increases oil field production and operation load.
Summary of the invention
Based on problem above, one purpose of the invention is to provide one kind and is free of the substances such as alkali, oxidant, non-corrosive
Sulphur removal-sterilization-inhibition one inorganic agent, have the characteristics that sulfur removal effectiveness it is high, selectivity it is good, take drugs and it is biodegradable.
The technical solution of the present invention is as follows:
The present invention provides a kind of sulphur removal-sterilization-inhibition one inorganic agent, including following weight percent composition:
Diallyl sulfide and Allifridin 20-30%,
Organic amine: polyethylene polyamine, diethylene diamine and triethylene tetramine 40-50%,
Formaldehyde 5-10%,
Cationic polyacrylamide and dimethylformamide 5-10%,
Alcohol 5-8%,
Surplus is water.
Sulphur removal-sterilization according to the present invention-inhibition one inorganic agent, based on cation polypropylene is added in the inorganic agent
The effect of amide adsorption-flocculation, the molecular weight of the cationic polyacrylamide are 300-500 ten thousand.
Sulphur removal-sterilization according to the present invention-inhibition one inorganic agent, sulphur removal, bactericidal effect based on the inorganic agent, with
And the considerations of each component cooperation homogeneity, the diallyl sulfide is diallyl trisulfide and/or diallyl two
Sulphur compound.More preferably, the diallyl sulfide is the diallyl trisulfide and two allyls of molar ratio 2-3:1
Base disulfide.
Sulphur removal-sterilization according to the present invention-inhibition one inorganic agent is removed after inorganic agent processing petroleum waste water
The more excellent setting of flocculating setting effect after sulphur, further includes hydrophobically modified chitosan 8-10%.More preferably, described hydrophobic to change
Property chitosan and cationic polyacrylamide weight ratio be 4-5:1.
Sulphur removal-sterilization according to the present invention-inhibition one inorganic agent, the alcohol are in methanol, ethyl alcohol, propyl alcohol or ethylene glycol
One or more.
The present invention provides sulphur removal-sterilization-inhibition one inorganic agent preparation method, comprising the following steps:
(1) organic amine is added into reaction kettle, after stirring is warming up to 65-68 DEG C, formaldehyde is slowly added dropwise into reaction kettle,
It is added dropwise to complete rear temperature control reaction, after reaction, under the vacuum condition of -0.5~-0.05MPa, 75-80 DEG C of temperature decompression is de-
Water, after obtain aminated compounds；
(2) after step (1), alcohol and water is added, is uniformly mixed；
(3) after step (2), diallyl sulfide and Allifridin is added in cooling, and mixing is equal
It is even；
(4) after step (3), cationic polyacrylamide and dimethylformamide is added, is uniformly mixed, that is, completes system
It is standby；
When including hydrophobically modified chitosan in component, it is added in step (4), and is uniformly mixed.
Preparation method according to the present invention must be appeared in court column chemical combination based on the polyamines and formaldehyde are carried out sound response
The purpose of object, in step (1), temperature control reaction temperature is 70-75 DEG C, and the reaction time is 2-3 hours.
Preparation method according to the present invention mixes the purpose of homogeneity based on each component during the preparation process, according to
Step each component and the aminated compounds sufficiently dissolve, and ingredient is uniformly mixed, stable components, in step (3), cooling mixing temperature
Degree is 60-70 DEG C.
The invention has the benefit that
Sulphur removal-sterilization of the invention-inhibition one inorganic agent, by polyamines+more sulphur compound system, in conjunction with other auxiliary agents
(cationic polyacrylamide and dimethylformamide) can achieve sulfur removal effectiveness height, and corrosion mitigating effect is good, the medicament and hydrogen sulfide
Product stability after reaction is good, and product small toxicity, can safety dumping；And its product can also react generation absorption with hydrogen sulfide
The stronger reactant of ability, to play good corrosion inhibition；The diallyl sulfide and diallyl thiosulfonic acid
Ester can play stable bactericidal effect, will not generate secondary pollution to petroleum；The addition of the cationic polyacrylamide can
So that the sediment after sulphur removal is settled through adsorption-flocculation, so that sewage is become clear, sulfur removal effectiveness is improved, dimethylformamide is further
Consolidate sulfur limitation effect, and keep inorganic agent each component mixing uniform, give full play to the sulphur removal of the complex treatment agent, inhibition and
Bactericidal effect.
Sulphur removal-sterilization of the invention-inhibition one inorganic agent can be not only used for disposing polluted water in oil, it may also be used for natural
Gas disposal when being used for natural gas processing, has (1) purification wide: can purification of acidic gas, mercaptan and thioether etc.；(2) degree of purification
High: purified hydrogen sulfide in natural gas content can be reduced to 6.0mg/L or less；(3) uptake is big: the absorption to sour gas
The advantages that can reach 1:120.
The preparation method is based on each component property, it is determined that specific preparation process and step mix each component equal
One, stablize, play the sterilization, sulphur removal and corrosion mitigating effect of the inorganic agent preferably, one inorganic agent sulphur removal effect obtained
Rate is high, and corrosion mitigating effect is good, and bactericidal effect is significant, meanwhile, small toxicity does not have apparent secondary pollution to petroleum.
