Description

一种油田杀菌剂及其制备方法 Oil field bactericide and preparation method

技术领域 FIELD

[0001] 本发明涉及一种油田杀菌剂及其制备方法,属于油田化学品技术领域。 [0001] The present invention relates to a method for preparing oil and bactericide, it belongs to the technical field of chemicals oil.

背景技术 Background technique

[0002] 在油田开采、集输及注水系统中,细菌对管线及其设备造成了严重的生物腐蚀,给油气生产带来了巨大的损失,因此杀菌工艺方法与高效杀菌剂在油田的应用显得尤为重要。 [0002] In the oil exploration, and water gathering system, apparatus and pipelines bacteria causing serious biological corrosion, oil and gas production due to the great loss, and therefore the sterilization process for efficient fungicide application appears in the field Particularly important.

[0003] 在油田生产和注水系统中,存在着多种微生物,如硫酸盐还原菌、铁细菌、腐生菌、 藻类、硫细菌、酵母菌、霉菌、原生动物等,其中数量最多,危害最大的是硫酸盐还原菌、铁细菌和腐生菌。 [0003] In the oil field production and injection systems, there are a variety of microorganisms, such as sulfate reducing bacteria, iron bacteria, saprophytic bacteria, algae, sulfur bacteria, yeasts, molds, protozoa, most numerous, the most harmful are the sulfate reducing bacteria, iron bacteria and saprophytes. 这些细菌在地下或设备中缺氧环境下大量繁殖,产生的代谢产物具有较强的腐蚀性,可引起钻采设备、注水管线及其它金属材料严重腐蚀,而腐蚀产物易与水中成垢离子反应生成污垢,造成管道堵塞和储层伤害;并且分泌大量粘性物质,附着在管道内壁上易形成铁质结瘤,堵塞管道,引起注水压力增大,注水量减小,原油产量与质量下降,严重时会造成重大事故。 These bacteria multiply in the ground or the apparatus anoxic environment, the metabolite produced a strong corrosive drilling equipment can cause serious corrosion of materials and other metal injection line, the corrosion products into the water and easily scale plasma reactor generation of dirt, causing clogging of the pipeline and reservoir damage; and secrete large amounts of viscous material, attached to the pipe wall is easy to form nodules of iron, plug the pipe, causing an increase injection pressure, injection rate decreases, and decrease the quality of crude oil production, serious cause a major accident when.

[0004] 而现有的杀菌剂,穿透剥离能力不强,不能进入菌落内部,进行杀菌作用;对硫酸还原菌、腐生菌的杀灭效果较差;对输送原油管路缓蚀性能不佳,仍有待进一步提高,且大多数市售杀菌剂会对环境造成二次污染。 [0004] and conventional fungicide, peeling penetration is not strong, can not enter the interior of the colonies, for sterilization; of sulfate reducing bacteria, saprophytic bacteria killing effect is poor; poor corrosion performance for transporting crude oil pipeline , it remains to be further improved, and most commercially available fungicides cause secondary pollution on the environment. 因此,开发一种新的杀菌剂,在采出水回注前进行预处理,有效控制细菌的生长和繁殖,避免或减少细菌造成的危害,对油田生产具有非常重要的现实意义。 Therefore, the development of a new fungicide, pretreatment before the produced water re-injection, effectively control the growth and reproduction of bacteria, avoid or reduce the harm caused by bacteria, has a very important practical significance to oil production.

[0005] 有机胍类抗菌剂无毒、无味、无刺激性,耐高温,抗菌性好,抗菌效果持久,对人体不存在致癌性、致变性和致畸性;有机醛类化合物是目前常用的非氧化型杀菌剂,其杀菌机理是:醛基通过抑制细菌细胞膜中蛋白质的合成,使蛋白质内部结构改变而造成细菌死亡; 阳离子表面活性剂具有表面吸附能力,降低溶液表面张力,在溶液中聚集,对粘泥有很强的剥离作用,抑制和杀灭微生物的效果,其杀菌机理是:通过阳离子吸附再带负电的细菌表面,改变细菌细胞壁的通透性而杀菌;季磷盐类化合物具有高效、广谱、低药量、低发泡、低毒、强污泥剥离、有较好的阻垢分散作用、对硫酸还原菌、腐生菌有很好的灭菌效果等优点, 由于磷原子半径比氮原子大,极化作用更强,使得季磷盐更容易吸附带负电子的细菌,因此杀菌率优于季铵盐,并且季 [0005] The organic antimicrobial agent guanidine odorless, non-irritating, high temperature resistance, antibacterial property is good, long-lasting antibacterial effect, the absence of carcinogenic to humans, denaturing and teratogenicity; aldehyde organic compound is commonly used in non-oxidizing biocides, sterilization mechanism which is: aldehyde by inhibiting the synthesis of protein in the bacterial membrane, the internal structure of the protein changes caused by the death of bacteria; cationic surfactants having a surface adsorption capacity, reducing the surface Zhang Li the solution, aggregation in solution , slime have a strong peeling action, the effect of inhibiting and killing microorganisms, bactericidal mechanism is: and then sterilized by cations adsorbed negatively charged bacterial surface, change the permeability of the bacterial cell wall; quaternary phosphonium salts of the compounds having high, wide, low-dose, low foaming, low toxicity, high sludge separation, the scale dispersant has good effect on sulfate reducing bacteria, saprophytes advantageous good sterilizing effects, due to the phosphorus atom larger than the radius of a nitrogen atom, more polarization, such that a quaternary phosphonium salt is more easily absorbed bacterial negatively charged electrons, thus sterilizing rate than quaternary ammonium salts, and quaternary 盐分子结构比较稳定,与一般氧化还原剂和酸碱都不反应,具有更广的pH适用范围,能很好的弥补阳离子表面活性剂在杀菌环境中受环境pH影响的不足;渗透剂能够大幅降低溶液的表面张力,使杀菌剂能更好的渗透进入粘泥或菌落内部,起到很好的杀菌效果。 Salt is relatively stable molecular structure, it does not react with the general acid-base and redox agent, having a pH of broader scope, can well compensate for the lack cationic surfactants are affected by the pH of the environment in the sterilization environment; penetrants can be greatly reduce the surface Zhang Li of the solution, the sterilizer can penetrate better into the internal colonies or slime, play a very good bactericidal effect.

[0006]目前,将有机胍类、有机醛类、季磷盐类、阳离子表面活性剂、渗透剂和水复配而成的油田杀菌剂还未见报道。 [0006] Currently, the organic guanidine, organic aldehydes, quaternary phosphonium salts, cationic surfactants, penetrants and water fungicide compound from oil has not been reported.
