The life safety issues currently in the Russian Federation and throughout the civilized world are one of the highest priority, as the life and health of citizens is the most important property of any state. In this regard, the security of both population and territory is one of the main tasks of the state. It requires the government to study the causes of accidents and disasters, to develop and improve the prevention of technogenic emergencies and deal with their forecasting. Emergency prevention, early intervention to reduce their risk, are events whose purpose is the preservation of home values of any state life and health of people. The study of the causes of emergency situations, the consideration of the past experience helps in the prevention of accidents in production, recovers the emergence and recurrence of disasters. On the basis of these tasks is a lot of different measures to prevent technogenic emergency situations of various character. The authors analyzed the effectiveness of these measures and determined the dependence of their number in our country in recent years, with the help of correlation analysis. Installed the dependence, equations of regression lines to predict and shows the effectiveness of the measures. The decrease in the values of emergencies is the life of the citizens of the country. Therefore preventive measures along with national research in this area will help to keep the main richness of the state life and health of, statistics, analysis.
APPLYING THE ELEMENTS OF THEORY OF DETERMINISTIC CHAOS FOR THE PROBLEM OF TECHNICAL DIAGNOSIS OF ESP
ESP units are widely used in oil and gas industry and that’s why attention to effective control of well stock with ESP is paid in terms of real-time technical condition evaluation of down-hole equipment.
Complex design and probability of failures of ESP are reasons for focusing on, but there are ways to prevent escalation to failure or reduce potential damage of equipment. Quality and efficiency of decisions on the technical condition of operating ESP is primarily depends on qualification of technical specialists of oil production. Fluctuations of electrical parameters during ESP operating are defined as stochastic process. There is huge amount of technological data indicating operating mode of ESP that could increase probability of incorrect technical condition evaluation of the equipment and a wrong decision on the operating mode.
Pasteurizing data it is a determination of operation parameters which adequately describe investigated object and processes in it that is the primary task under the realization of technical diagnosis.
This paper proposes the way of applying diagnostic criteria for ESP technical condition evaluation based on analysis of stochastic fluctuation operating parameters in timescale form. Proposed criteria provide preliminary data cleaning to reduce the time of technical condition evaluation of ESP unit.
