An attempt is made to reveal the main reasons for the inefficiency of environmental protection measures to eliminate the consequences of environmental pollution as a result of accidental oil spills during the operation of oil and gas fields in the Middle Ob region. In recent years, the growing reliability of oilfield equipment has resulted in the trend to reduced formation of new oil-contaminated sites and the higher pace of restoration of old previously uncultivated sites. However, this trend does not reflect the true state-of-art, since the application of standard reclamation technologies does not fully take into account the characteristics of a particular site, as a result of which the undertaken nature-protection measures are ineffective. This is manifested in a longer time needed for natural environment restoration, and as a rule, it leads to secondary contamination of the adjacent territory. The main stages of eliminating the consequences of accidental oil spills and their ingress on dry valleys and water bodies are discussed. Proceeding from the main reclamation stages, the author presents his viewpoint on improving the effectiveness of environmental measures during reclamation, taking into account the physical and geographical conditions of the region and the characteristics of the pollution site.

Keywords: environment, emergency spill of petroleum products, oil-contaminated lands, hydraulic lock, reclamation
