Підвищення екологічної безпеки видобування вуглеводнів шляхом вивчення сумісності супутньо-пластових вод при поверненні в надра

Abstract

This paper describes the possibilities of assessing the associated formation waters of oil and gas condensate deposits compatibility to prevent emergencies when returning to the subsoil. The possible options for mixing the return waters with the waters of the intake formation, the optimal conditions for the preparation of associated formation waters to improve the environmental safety of the return process have been evaluated. A decrease in the concentration of iron (II) as a result of ozonization of water, the presence of which contributes to clogging, the deterioration of the carrier bed intake and, as a result, the accidents, has been confirmed. It is proposed to use test methods for assessing the iron (II) and iodine content in order to be able to quickly respond to possible developments in order to improve environmental safety at the return points of formation water. Ecological safety is the basis of the process of hydrocarbon production at all stages of the technological cycle of hydrocarbon production, including the return of the associated formation waters to the subsoil.
