Economic efficiency of the application of artificial air cooling for normalization of thermal conditions in oil mines

Abstract

This work substantiates a technical solution for improving the working conditions for the thermal factor in oil extraction by the thermoshaft method using the mine refrigeration technology. A review of manufacturers and technical characteristics of refrigeration technology in Russia, CIS countries, and Western Europe was conducted. For the selected set, the economic eciency of the project was assessed, and a conclusion was made about the feasibility of implementing this project solution. It was shown that the use of a water-cooling machine in the mine air conditioning system would reduce the air temperature in the oil production gallery to the required values and allow abandoning the long-term construction of a surface stationary refrigeration station. The normalization of the thermal regime reduces the costs of bene ts and compensation for work in harmful labor conditions and improves the quality of service of production wells by operators. The project for the introduction of air conditioning has a high level of pro tability, and its payo will occur in the second year of operation.
