Summary The article considers statistical data on accident rate in oil production: types of accidents, accident distribution over constituents of the Russian Federation, number of fatalities, incident distribution over constituents of the Russian Federation. Causes initiating fire and explosion hazardous situations on a drill site are studied. Executed analysis of statistical data clearly demonstrates that accident rate and fatal injuries in the industry still remain at high level, therefore necessity to develop scientifically validated methods for assessment of well hazards from various condition is relevant. In its turn, it will enable to promptly provide preventive measures aimed at assurance of the required industrial safety level. As drill sites belong to hazardous industrial facilities (HIF), when managing industrial safety, at construction design stage, it is necessary to carry out accident risk analysis in order to identify hazards and undesired events. According to the analysis of problem statistics, criteria that influence on occurrence probability of problems initiating fire and explosion hazardous situations, as well as the factors, on which severity of accident consequences depend, are determined. As a result of the work executed a method for calculation of quantitative risk assessment indices that considers well construction conditions is proposed on the basis of the developed well hazard level matrix. The proposed approach can be applied to forecast risk level for any territory when using initial data on accident rate of the specific field or group of fields. |
