technological solution for the prevention and disposal of TRNE

Problem description

The formation of persistent TRNE in the fields entails economic losses associated with its ballast pumping, and the presence and accumulation of the industrial layer in the apparatus of the oil treatment unit (OPF) and reservoirs leads to a failure in the preparation of oil to the required quality group. All this leads to more serious risks and economic costs for retraining

Purpose and description of task (project)

In the process of transport production and oil preparation in the field, the process of formation of oil emulsions occurs caused by transient dynamic processes in pipelines and the transport system, chemical processes in all technological cycles of the oil field, including those caused by conflicts of residual doses of chemical reagents in various technological cycles, transient thermodynamic preparation processes oil, and changing parameters and composition of produced oil. The emulsion that appears at different cycles due to the peculiarity of the oil composition and the content of resins and asphaltenes in it, as well as the high salinity of formation water, in combination with mechanized production and other dynamic processes of the oil field, forms TRNE at the final cycle of oil preparation in reservoirs. TRNE negatively affects the efficiency of the oil production and treatment process, and also creates additional disposal costs and environmental payments. In the course of research work, it is necessary to determine the main factors influencing the occurrence of TRNE, select or develop technologies that prevent the formation of TRNE, and develop technologies for the destruction and further processing and disposal of TRNE with a reduction in the negative impact on the environment. Determining the reasons for the formation of TRNE and developing recommendations for its destruction and recycling technologies.
