Energy-saving technologies in the operation of oil fields

Abstract

The analysis of peculiarities for functioning of the enterprise aimed at the development of an oil field located in the Arctic zone of Russia is presented. The specific energy consumption for oil and oil-containing liquids production, preparation and transportation of a marketable product are identified. Based on the assessment of the facility’s energy systems condition and world experience in the field of energy saving in the operation of oil fields in severe northern conditions, the used and potential energy-saving technologies have been analyzed. A more complete use of the energy of associated petroleum gas, taking into account its significant contribution to air pollution, based on the utilization of exhaust gases heat, will reduce heat pollution and excessive diesel fuel consumption in boiler houses for facility heating. From the point of view of increasing energy efficiency of the heat supply system, it is proposed to increase the heat-shielding performance of facilities, in particular the rotational field camp, the use of modern automated heat points with weather control. According to the study results, when generating electricity with the use of a gas-turbine drive, a non-regenerative cycle is used accompanied by releasing high-temperature exhaust gases. It is proposed to use gas turbine units with a regenerative cycle during the development of oil fields and to consider the possibilities for using a combined cycle. To increase the energy efficiency of pumps responsible for the formation pressure increase and oil transportation systems, it is recommended to implement a variable frequency drive. To reduce inefficient energy consumption, it was proposed to install additional temperature sensors in the electrical heating system for oil pipelines. As well as the possible options for energy consumption reduction through the use of wind generators, cogeneration based on solar energy and heat pumps are described.
