Description
技术领域
本发明属于石油工业用化学品技术领域,尤其涉及一种防止硫酸盐还原菌(SRB)腐蚀的抑制剂配方及其制备方法。在油井防止硫酸盐还原菌的过程中,在0.05~0.1%加量的情况下,使***中硫酸盐还原菌的含量小于25个/ml。
背景技术
硫酸盐还原菌(SRB)是一种以有机物为营养物质的厌氧型细菌,广泛存在于土壤、海水、河水、地下管道、油气井等处。硫酸盐还原菌(SRB)可将水中的硫酸盐还原为硫化氢,使局部区域的pH值下降到4以下,是低碳钢、低合金钢镍合金、奥氏体不锈钢、铜合金钢产生严重的点蚀,并形成黑色的硫化铁沉淀物。另外,对水泥的腐蚀也相当严重,会引起玻璃钢设备表面疏松和孔蚀。它不仅会造成管线腐蚀穿孔,而且会促进其它细菌的生长繁殖,产生大量的粘泥,堵塞管线,给工业生产带来严重损失。微生物的生命活动产生的硫化物和硫化氢等恶化了环境,同时也危害人类的健康。微生物腐蚀在金属和建筑材料的腐蚀破坏中占20%左右。美国生产油井中发生的腐蚀77%以上是由SRB造成的,美国每年因微生物直接造成的损失达300~500亿美元。我国油田也存在由硫酸盐还原菌(SRB)引起的腐蚀问题,例如***每年用于硫酸盐还原菌(SRB)杀菌剂方面的费用高达6千万元(人民币)。
硫酸盐还原菌(SRB)腐蚀的危害不仅在于其对设备的腐蚀,而更重要的是其引起的腐蚀的突发性,给工业生产带来严重的影响,使得人们越来越重视研究它的防治方法。其中,投加杀菌剂是目前最常用的方法,但由于硫酸盐还原菌(SRB)常与其他微生物共存于微生物产生的多糖胶中而被保护起来,杀菌剂不易穿透,以及其处于硫化氢的还原性环境中,使得一般的氧化型杀菌剂很难起到有效的杀菌效果;生物膜的存在,使杀菌效率降低、甚至失效,以至于产生耐药菌。并且杀菌剂的大量使用,也给环境治理带来新的负荷。同时价格高,从而影响了生产***的正常运行。
发明内容
本发明的目的是:提供一种防止硫酸盐还原菌腐蚀的抑制剂的配方及其制备方法。在油井防止硫酸盐还原菌的过程中,在0.05~0.1%加量的情况下,使原油生产***中的硫酸盐还原菌的含量小于25个/ml。

利用本发明自2007年起分别在华北油田的30多口SRB腐蚀严重的油井上试用,在0.05~0.1%加量的情况下,很好在抑制了SRB的腐蚀。
典型井例:晋95-7腐蚀严重,07年共作业3次(分别在1月份、7月份、10月份)。11月份我们根据现场观察发现伴生水呈黑色,含大量粉末,是典型的硫酸盐还原菌(SRB)腐蚀特征。11月取样分析细菌含量,结果是硫酸盐还原菌10000个/ml,不含腐生菌(TGB)。
高浓度的细菌活动破坏了杆管表面的保护膜,另外SRB的铁腐蚀产物是FeS,FeS颗粒极细,有很强的吸附能力,FeS颗粒不断吸附长大,逐渐沉积在泵筒里,堆积到一定程度造成光杆下不去,在车城油田频繁出现的这种情况主要就是硫酸盐还原菌(SRB)腐蚀的结果。
如何控制硫酸盐还原菌(SRB)含量是我们要解决的问题,在没有过多方案可以选择的情况下,我们做了硫酸盐还原菌(SRB)抑制剂的对污水的室内试验,试验结果表明,硫酸盐还原菌(SRB)抑制剂能有效抑制SRB繁殖,腐蚀率明显下降。
硫酸盐还原菌(SRB)抑制剂室内试验数据
使用浓度mg/l | 空白 | 20 | 40 | 60 | 80 | 100 |
SRB浓度mg/l | 10000 | 100 | 100 | 100 | 0 | 0 |
腐蚀率mm/a | 0.1664 | 0.0852 | 0.0780 | 0.0748 | 0.0736 | 0.0729 |
11月27日对晋95-7井进行了洗井,11月30日首次在晋95-7井加入200KgSRB抑制剂,12月16日第2次加入150Kg,连续观察产出水中的细菌含量和腐蚀率,从监测结果看细菌含量稳定在100个/ml,腐蚀率在0.09mm/a以内,污水变清,黑色悬浮物明显减少,说明SRB腐蚀产物FeS含量下降,腐蚀得到抑制。
现场试验情况
取样日期 | 11.30 | 12.03 | 12.13 | 12.18 | 12.26 |
SRB浓度mg/l | 10000 | 100 | 100 | 100 | 100 |
腐蚀率mm/a | 0.1664 | 0.0952 | 0.0948 | 0.0745 | 0.0402 |
从现场试验效果看,用SRB抑制剂控制硫酸盐还原菌(SRB)含量,从而抑制腐蚀是可行的。
