Abstract
Reduction of harmful effects of industrial emissions into the atmosphere are important issues of the fuel and energy complex. In connection with this problem, injection of flue gases into oil fields for enhanced oil recovery can be considered as an environmentally safe and economically rational way to reduce emissions and beneficial use of greenhouse gases. Flue gases generated at power plants or in other industrial processes associated with combustion of fossil fuels - natural gas, fuel oil, coal, etc. - can be used for injection into the reservoir.
When steam is used in oil production, high oil displacement ratios are achieved, but problems often arise due to high costs of steam production and treatment of produced water. The problem arises when these costs become unprofitable. The problem can be solved by reducing the volume of injected steam by using flue gas.
Purpose of research: study of influence of vapor-gas impact modes on oil displacement efficiency.
Object of research: unconsolidated core samples from well X of PJSC Tatneft.
Research methods: OST 39-195-86. Oil. Method for determination of oil displacement coefficient in laboratory conditions.
Research results: Analysis of oil displacement coefficient under the following exposure modes: oil displacement by steam and steam with flue gases at different ratios of steam and gas. Determination of the optimal ratio of steam and flue gas for effective oil displacement.
