【摘要】 以发光细菌冻干粉为实验生物 ,研究出了中国陆上油田用化学剂和钻井液生物毒性检测新方法 ,其原理是 :根据发光细菌相对发光度随样品毒性总体浓度的增高而呈线性降低的特性 ,测定发光细菌在接触样品 15min后的发光量 ,得出油田化学剂及钻井液的毒性水平。该方法及毒性分级简单易行 ,快速简洁 ,可操作性强。结合中国陆上油田的实际情况 ,给出了划分油田化学剂和钻井液毒性的等级标准 ,并依据该标准对目前中国陆上油田所使用的部分油田化学剂及钻井液的毒性进行了检测与评价 ,从而验证了油田化学剂和钻井液生物毒性检测新方法及毒性分级标准的可行性。更多还原

【Abstract】 Using luminescent bacteria as the testing medium, a new biotoxicity testing method for oilfield chemicals and drilling fluids was worked out. The principle is, based on characteristics of luminescent that the luminosity decreases lineally with the bulk toxicity concentration of the sample, measure the luminosity in 15 min after the luminescent bacteria touching the sample, then decide the toxicity level. This testing method and toxicity grading is simple and convenient. According to actual condition of onshore oilfield,grading standard for oilfield chemicals and drilling fluid is presented. Some oilfield chemicals and drilling fluids were tested based on the standard to verify the feasibility of the new study.更多还原
