摘要

研究了卢克石油-乌赫塔内石油天然气公司（LUKOIL-Ukhtaneftegaz RPC）生产设施的储层水（废水）和地表水（注入储层）的化学成分和对生物-水生生物的毒性。结果表明，高矿化度的地层水对水蚤、单细胞绿藻和鱼苗具有急性毒性，将样品稀释 2-100 倍后即可消除毒性。计算了所研究水样对试验生物的致死稀释比 LDR50 指标和致死浓度 LC50，其范围为 10,780 至 27,910 毫克/升，平均为 21,140 毫克/升。结论是，所研究的地层水样本与 10 毫克/升的标准半数致死浓度有显著的正向差异（3-4 个数量级），不能被归类为对自然环境造成危害的物质。

Experience in Assessing the Toxicity of Formation (Produced) Water of the LUKOIL-Ukhtaneftegaz RPC for the Environment

The chemical composition and toxicity for living organisms-aquatic organisms of reservoir (waste) and surface (for injection into reservoir) waters of production facilities of the LUKOIL-Ukhtaneftegaz RPC were studied. It has been established that highly mineralized formation waters have acute toxicity for daphnia, green unicellular algae and fish fry, which is eliminated by diluting the samples 2–100 times. Indicators of the Lethal Dilution Ratio of LDR50 and lethal concentrations of LC50 of the studied water samples were calculated for test organisms, which ranged from 10,780 to 27,910 mg/l, averaging 21,140 mg/l. It was concluded that the studied samples of formation water, which differ significantly (by 3–4 orders of magnitude) in a positive direction from the standard LC50 concentration of 10 mg/l, cannot be classified as substances that pose a hazard to the natural environment.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
