Abstract
As per item 353 and Appendix № 6 of the Federal norms and rules in the field of industrial safety «Safety rules in the oil and gas industry», the smallest distance between the mouths of pro- duction gas and gas condensate wells is 40 m. According to the
Federal norms and rules in the field of industrial safety «Gene- ral requirements for substantiation of safety of a hazardous pro- duction facility» this substantiation should include the list of activities containing additional safety measures, compensatory deviations from the requirements of the regulatory documents.
To confirm sufficiency of the compensatory measures, the re- sults of studies, calculations, tests, simulation of emergency si- tuations, risk assessment or analysis of operating experience of similar hazardous production facilities are required. At the well pads of oil, gas and gas condensate wells the most hazardous accidents are open uncontrolled blowouts at the wellheads with jet fire occurrence.
The indicators, which are traditional for the quantitative risk as- sessment, in this case cannot adequately characterize the degree of hazard due to lack at the similar facilities of the workplaces, in which permanent stay of the personnel is provided. Therefore, when substantiating the reduction of the distances between the gas and gas condensate wellheads, the criterion of compensatory measures sufficiency may be the time during which the absorbed dose of thermal radiation at the adjacent equipment will reach the threshold value. If this threshold is exceeded, the equipment can be considered destroyed. The main safety measure in case of deviations from the established requirements for the distances between the mouths of the gas and gas condensate wells is the installation of the downhole shut-off valve.
Key words: well, gas production, industrial safety require- ments, quantitative risk assessment, accident, escalation, com- pensatory measures, substantiation of safety, downhole shut-off valve.
