When oil mining method is used in the LUKOIL-Komi LLC (Yaregskoye field), there is a problem of deterioration of sanitary and hygienic working conditions of miners in the mine oil, associated with an increase in air temperature in the drilling gallery in the slope block. To combat this negative phenomenon Yareganeft is now implements wells drilled from the surface for outside air supply. Reducing the temperature in the gallery may be provided only a in the case of cooling air supplied to the well. It is known, the air conditioning systems consumes a tremendous amount of power. In addition, during the cold season according to the safety rules the air supplied has to be heated to a temperature above 2 °C. In this case the amount of energy consumed is also significant. All these aspects contribute to the increase of crude oil cost and reservoir cooling reduces production efficiency.
The article provides a method for ventilating the oil mine unit without cooling the air supplied to the drilling gallery. Removing the heated air it is assumed using ventilation hole by the action of natural draught (thermal depression) and reinforcing its action by a deflector and surface fan. Airing outgoing excavations carried a fan of local ventilation, performing sampling of the incoming fresh air to evade the block. The entire process is carried out in an automated mode.
As a result of the comparative analysis based of data on actual measurements in the oil mine NSh-1 Yareganeft it was found that the proposed method of ventilation saves energy and provides the required sanitary and hygienic conditions of work much more effectively than the method implemented at the moment.
