UTILIZATION OF THE HEAT ENGINE DRIVING THE COMPRESSOR AND THE EXCESS AIR WHEN DRILLING EXPLORATION WELLS WITH AIR PURGE

Drilling with air purge under specific conditions has several advantages. For the drilling of exploratory wells with a purge air is a used mainly mobile compressor station with internal combustion engine (ICE). However, in this case the energy intensity increases due to the use of drilling rigs of compressor, a drive power which is considerably greater than the pumps used in similar conditions.
Analysis mobile compressor units work shows that a substantial portion of energy losses in the engine driving the compressor, since not all the combustible fuel is converted into useful power. A larger amount of heat is removed from the engine cooling system and is carried away with the exhaust gases.
In this article we discussed the possibility of increasing the efficiency of drilling wells with scavenging air by the use of a utilization installation of heat drive the compressor and excess air.
