一种油田杀菌剂及其制备方法 One kind of oil bactericide and preparation method

技术领域 TECHNICAL 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 bactericide and belongs to the technical field of oilfield chemicals.

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 oil exploration, gathering and injection system, the bacteria of the pipeline and its equipment causing serious biological corrosion, to oil and gas production brought huge losses, and therefore the sterilization process for efficient fungicide application in the field appear 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 production and water injection systems, there are a variety of microorganisms, such as sulfate-reducing bacteria, iron bacteria, saprophytic bacteria, algae, sulfur bacteria, yeasts, fungi, protozoa, where the largest number of the most harmful 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 in the ground or equipment under anoxic environment multiply, metabolites has a strong corrosive, can cause drilling equipment, water pipelines and other metallic materials, severe corrosion, and corrosion products easily with water into the dirt ionic reaction generate dirt, causing the pipes get clogged and reservoir damage; and secrete large amounts of viscous material, attached to the pipe wall is easy to form iron nodulation, clogging pipes, causing water pressure, water injection to reduce the yield and quality of crude oil fell seriously when it will cause a major accident.

[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 the existing fungicide penetration stripping ability is not strong, can not enter the interior of colonies, sterilizing effect; sulfate reducing bacteria, poor KILLING saprophytic bacteria; for transportation of crude oil pipeline corrosion and poor performance , 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 produced water reinjection, effective control of bacterial growth and reproduction, to avoid or reduce the harm caused by bacteria, has a very important practical significance for 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,并且季磷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。 [0005] The organic guanidine antimicrobial agents, non-toxic, tasteless, non-irritating, high temperature, good anti-bacterial, anti-bacterial lasting effect on the human body there is no carcinogenic, teratogenic and caused degeneration; aldehyde organic compound is currently used non-oxidizing biocides, sterilization mechanism which is: aldehyde by inhibiting the synthesis of bacterial cell membrane protein, the internal changes in the protein structure caused by the death of bacteria; cationic surfactants having adsorption capacity, reducing the surface tension of the solution, aggregation in solution , slime has a strong spin-off effect, suppression and killing microbial effect, the mechanism of sterilization: sterilization by cation adsorption and then negatively charged surface of bacteria, changing the bacterial cell wall permeability; quaternary phosphonium salt compound having high, wide, low-dose, low foaming, low toxicity, high sludge separation, has good scale inhibition and dispersion effect on sulfate-reducing bacteria, saprophytes have a good sterilization effect, etc., due to the phosphorus atom large radius than nitrogen atoms, more polarization, such quaternary phosphonium salt is more easily absorbed with negative electron bacteria, so the sterilization rate than quaternary ammonium salts, quaternary phosphonium salts and molecular structure is relatively stable, with the general redox and acid do not base reaction, with pH suitable for a wider range, can be very good to make up for lack of a cationic surfactant affected by environmental pH in the sterilization environment; penetrant can significantly reduce the surface tension of the solution, so that the fungicide can better penetrate into slime or internal colonies, play a 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 field of organic fungicides guanidine, organic aldehydes, quaternary phosphonium salts, cationic surfactants, penetrants and water mixed together has not been reported.
