[Energy requirements of workers engaged in the underground repair of oil wells in the Azerbaijan SSR].

The energy requirement of workers engaged in the underground repair of oil wells has been evaluated. The energy expenditure during the 8-hour shift with the use of manual and mechanized labor was determined on the basis of the 7-day chronometric charts of their labor activity. The power consumption of 32 descending-lifting and preparative-conclusive operations was evaluated by the indirect calorimetry. Energy expenditure in the time off was studied by the questionnaire method during a week. It was established that, as it was calculated for standard body mass (70 kg), the daily energy expenditure of an operator comprised 3190 kcal (fluctuations depended on the use of mechanization means, 3125-3398 kcal), of his assistant--3487 kcal (3434-3644 kcal), machine driver of the tractor-elevator--3013 kcal (2965-3100 kcal). On the basis of the data obtained the work of the operator and machine driver has been referred to the III, and that of the operator's assistant to the IV occupational group with respect to the intensity of their labor.
