摘　　要：油田注水管线内壁的固着菌对水质的稳定性具有较大影响,为了能真实反映油田注水系统中固着菌的生长状况及对系统的影响,研制了适合油田注水系统的固着菌取样器,并优化筛选了渗透剥离能力强的固着菌杀菌剂,在胜利油田胜利采油厂宁海站进行了应用试验。试验结果表明:研制的取样器可实现现场固着菌原位取样;在试验周期内材料表面附着了大量固着菌,并存在一定程度的微生物腐蚀;筛选的杀菌剂具有高效生物膜剥离能力,可有效控制管壁固着菌的生长。It is found in the process of oilfield water reinjection that the biological membrane on the pipes has significant impacts on water quality.In order to reflect the influences of biofilm growth on the water injection system,a biological membrane sampler for oilfield water injection system was developed and application tests were carried out at Ninghai Station of Shengli Oil Produciton Plant.The test result showed that the developed sampler could achieve on-site sampling for fixed biofilm.Large amount of bacterium and a certain degree microbiological corrosion were also found on the surface of materials.The chosen bactericide had a high efficient ability of biofilm stripping,which could control the growth of bacterium fixed on the pipes.
