Abstract
The invention relates to bactericide for oil fields, in particular to poly-guanidine SFT bactericide. The poly-guanidine SFT bactericide solves the technical problems of sterilizing and removing impurities in re-injection water in oilfields and waste water in oil refineries, and comprises the following raw material by weight in parts: 10-15 parts of hydrochloric polyhexamethylene guanidine, 2-4 parts of geramine, 5-7 parts of polyhexamethylene biguanidine, 1-3 parts of chlorine hydride guanidine, 2-4 parts of ferric sulfate and 20-30 parts of water. The poly-guanidine SFT bactericide can be adopted as the bactericide and water treatment agent of the re-injection water in the oilfields and the waste water in the oil refineries, not only has excellent anti-bacterial effect and sterilization effect, but also has a certain flocculate action, has no bubbles while being mixed with water, does not need de-foaming agent, and has good effects to accumulating oil, displacing oil and treating waste water.
Description
Technical field
The present invention relates to a kind of oil field bactericide, be specially a kind of poly-guanidine SFT bactericide.
Background technology
Oil field recharged waste water bacterial content is generally higher, generally comprise sulfate reducing bacteria, saprophytic bacteria, iron bacteria etc.The raised growth of bacterium and breeding, not only, to the reservoir obstruction that causes damage, affect development effectiveness, causes oil recovery factor to decline, and water injection well pressure is increased, and water injecting consumption rises.Meanwhile, the corrosion of aggravation surface line, equipment and pit shaft, finally causes Development Response of Oilfield variation, and production cost rises, and overall efficiency declines, and then seriously restricts the sustainable development in oil field.In order to overcome this problem, we take to add in re-injection water the mode of bactericide to carry out sterilization processing.The bactericide that tradition is used is all the compositions such as chloride, phosphorus, formaldehyde, and these materials itself are combustion-supporting, and high poison, have strong impulse smell, corrosion skin, and meeting combustible can burn, blast, volatile, tool is not long-lasting, and transportation is very inconvenient.Usage amount is large, and careless manipulation can cause permanent damage to water table, makes descendants thoroughly lose valuable backing water source, and this material of while is stimulation applications personnel's skin seriously, eyes, and mucous membrane, Long Term Contact is also easily carcinogenic.As sulfate reducing bacteria, not only can engulf oil, and can make all polymer degrade, make polymer displacement of reservoir oil decrease in efficiency, cost increases.Having is exactly widely used formaldehyde again, and not only necessary use every day, and concentration must surpass a certain amount of, otherwise not only can not kill bacterium, becomes on the contrary bacterium nourishing agent.On long terms, usage amount is large, and cost is high, and can cause serious environmental pollution.In oil field waste, except containing a large amount of bacteriums, also there is a large amount of suspensions, colloid, emulsification oil droplet, when adding bactericide in general wastewater treatment process, also need to add flocculant.
Poly-guanidine is also a kind of bactericide, take and gather the bactericide that guanidine is raw material and have at present number of patent application as 201010202497.7 disclosed oilfield reinjection water sterilizing agents, in this technical scheme, disclose with fourth diamino, guanidine sulfate, polyhexamethylene guanide, polyolefin guanidine is the bactericide that raw material is made, and can effectively solve the problem that in the backwater of oil field, various varied bacteria growings pollute.< < Liaoning chemical industry > > 1999.11. " Bactericides for Oilfield Water present situation and development trend " literary composition, highlighted the conventional several bactericide of oil field water, the problem of sterilization mechanism and existence.But in fact bactericide is used seldom separately, be all generally composite use, to reach best bactericidal effect.Particularly in oil field reinjection water or oil refinery waste water processing, using, in this type of water, except containing various bacteriums, also contain the organisms such as algae, primary small animal, also have various suspensions, is also to affect the disadvantage factor that plant equipment runs well.Although novel poly-guanidine bactericide can effectively be killed various bacteriums, this detects in laboratory is can reach sterilization effect completely, but the general more complicated of environment of considering the microorganism existence of down-hole, single poly-guanidine series bactericidal agent sometimes can not produce a desired effect completely.
Summary of the invention
The present invention provides a kind of poly-guanidine SFT bactericide in order to solve the technical problems such as sterilization removal of impurities of oil field reinjection water and oil refinery waste water.
The present invention is realized by following technical scheme, a kind of oilfield reinjection water sterilizing agent, raw material by following weight ratio example forms, Polyhaxemethylenguanidine Hydrochloride 10-15 part, clean youngster go out 2-4 part, PHMB 5-7 part, hydrogen chloride guanidine 1-3 part, iron sulfate 2-4 part, water 20-30 part.
Preparation method is, first water and iron sulfate and clean youngster being gone out and added in proportion in reactor, is to stir 10 hours under 100-110 ℃ of condition in temperature, after having reacted, is cooled to normal temperature, again Polyhaxemethylenguanidine Hydrochloride, PHMB, hydrogen chloride guanidine are added, be then uniformly mixed.
On the basis of technique scheme, the oilfield reinjection water sterilizing agent with best-of-breed technology effect, raw material by following weight ratio example forms, 12 parts of Polyhaxemethylenguanidine Hydrochlorides, clean youngster go out 3 parts, 6 parts of PHMBs, 2 parts of hydrogen chloride guanidines, 3 parts, iron sulfate, 25 parts, water.
This invention can be used as bactericide and the water treatment agent of oil field reinjection water and oil refinery waste water, not only has excellent restraining and sterilizing bacteria effect, but also has certain flocculation, mix non-foaming with water, without using defoamer, to the poly-oily displacement of reservoir oil, waste water treatment has suitable effect.Can make in oilfield exploitation re-injection water treatment procedure, needn't re-use defoamer, make water injection technology program simplification, the destruction of the bactericide Use out of range of avoiding using the materials such as described chloride, phosphorus, formaldehyde at present to water table, and this bactericide is to the fungi in oil field reinjection water, heterotrophic bacteria, algae, particularly saprophytic bacteria, sulfate reducing bacteria, iron bacteria have special efficacy.And this bactericide has no irritating odor, the skin nonirritant to directory operator, while stable chemical performance, sterilizing time is long-acting, does not burn, do not explode, transportation storage safe.Particularly this bactericide is compound cationic polyelectrolyte, anion and organic matter nonionic class material are had to good adsorption-condensation effect, grease particle in adsorbed water, plays polymerization displacement of reservoir oil effect well, can be applied to the processing of oil refinery waste water.
