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 and use bactericide, be specially a kind of guanidine SFT bactericide that gathers.
Background technology
Oil field return water bacterial content is generally higher, generally comprise sulfate reducing bacteria, saprophytic bacteria, iron bacteria etc.Raised growth of bacterium and breeding not only to the reservoir obstruction that causes damage, influence development effectiveness, cause oil recovery factor to descend, and water injection well pressure is increased, and water injecting consumption rises.Simultaneously, the corrosion of aggravation surface line, equipment and pit shaft finally causes the oil field development deleterious, and production cost rises, and overall efficiency descends, and then seriously restricts the sustainable development in oil field.In order to overcome this problem, the mode that we take to add bactericide in the re-injection water is carried out sterilization processing.The bactericide that tradition is used all is compositions such as chloride, phosphorus, formaldehyde, and these materials itself are combustion-supporting, and high poison, have strong impulse property smell, corrosion skin, and meeting combustible can burn, blast, volatile, tool is not long-lasting, and transportation is very inconvenient.Usage amount is big, and careless manipulation can cause permanent damage to underground water layer, makes the descendants thoroughly lose valuable reserve water source, and this material of while is stimulation applications personnel's skin seriously, eyes, and mucous membrane, long-term contact is also carcinogenic easily.Like sulfate reducing bacteria, not only can engulf oil, and all polymer are degraded, make the polymer displacement of reservoir oil decrease in efficiency, cost increases.Having is exactly widely used formaldehyde again, not only must every day use, and concentration must surpass a certain amount of, otherwise not only can killing bacteria, become the bacterium nourishing agent on the contrary.On long terms, usage amount is big, and cost is high, and can cause serious environmental pollution.Except that containing a large amount of bacteriums, also there are a large amount of suspensions, colloid, emulsification oil droplet in the oil field waste, also need add flocculant when adding bactericide in the general wastewater treatment process.
Gathering guanidine also is a kind of bactericide; To gather guanidine is that number of patent application is arranged at present is 201010202497.7 disclosed oilfield reinjection water sterilizing agents for the bactericide of raw material; In this technical scheme, disclose with fourth diamino, guanidine sulfate, polyhexamethylene guanide; Polyolefin guanidine is the bactericide that raw material is processed, and can effectively solve various varied bacteria growing pollution problems in the backwater of oil field." Liaoning chemical industry " 1999.11. " Bactericides for Oilfield Water present situation and development trend " literary composition has highlighted oil-field brine some kinds of bactericide commonly used, the problem of sterilization mechanism and existence.But in fact bactericide uses seldom separately, generally all is composite use, to reach best bactericidal effect.Particularly in oil field reinjection water or oil refinery waste water processing, using, except containing various bacteriums, also contain organisms such as algae, primary small animal in this type of water, also have various suspensions, also is to influence the disadvantage factor that plant equipment runs well.Though novel gather guanidine bactericide and can effectively kill various bacteriums; This detects in the laboratory is can reach sterilization effect fully; But consider the general more complicated of microorganism survival environment of down-hole, single gather the guanidine series bactericidal agent and sometimes can not produce a desired effect fully.
Summary of the invention
The present invention is for technical problems such as the sterilization removal of impurities that solves oil field reinjection water and oil refinery waste water and a kind of guanidine SFT bactericide that gathers is provided.
The present invention is realized by following technical scheme; A kind of oilfield reinjection water sterilizing agent; Raw material by following weight ratio example is formed, Polyhaxemethylenguanidine Hydrochloride 10-15 part, clean youngster go out 2-4 part, polyamine propyl group biguanides 5-7 part, hydrogen chloride guanidine 1-3 part, iron sulfate 2-4 part, water 20-30 part.
The preparation method is, water and iron sulfate and clean youngster are gone out adds in the agitated reactor earlier in proportion, is stirring 10 hours under the 100-110 ℃ of condition in temperature; Reaction is cooled to normal temperature after accomplishing; With polyhexamethylene guanide, polyolefin guanidine adds again, mixes then to get final product.
On the basis of technique scheme; Oilfield reinjection water sterilizing agent with best-of-breed technology effect; Raw material by following weight ratio example is formed, 12 parts of Polyhaxemethylenguanidine Hydrochlorides, clean youngster go out 3 parts, 6 parts of polyamine propyl group biguanides, 2 parts of hydrogen chloride guanidines, 3 parts in iron sulfate, 25 parts in water.
This invention can be used as the 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; Need not to use antifoaming agent, to gathering the oily displacement of reservoir oil, waste water treatment has suitable effect.Can make in the oilfield exploitation re-injection water treatment procedure; Needn't re-use antifoaming agent; Make the water injection technology program simplification; The bactericide excess that avoids the use of materials such as at present described chloride, phosphorus, formaldehyde is used the destruction to underground water layer, and this bactericide is to the fungi in the oil field reinjection water, heterotrophic bacteria, algae, particularly saprophytic bacteria, and sulfate reducing bacteria, iron bacteria have special efficacy.And this bactericide has no irritating odor, to the skin nonirritant of directory operator, and the while stable chemical performance, sterilizing time is long-acting, does not burn, and does not explode the transportation storage safe.Particularly this bactericide is compound cationic polyelectrolyte; Anion and organic matter nonionic class material there is good adsorption-condensation effect; Grease particle in the adsorbed water plays polymerization displacement of reservoir oil effect well, can be applied to the processing of oil refinery waste water.
