НЕФТЯНАЯ ПРОВИНЦИЯ

Abstract

​

This paper presents the results of the laboratory study of nitrogen injection into a reservoir to increase oil recovery and considers the effects of this technology on the process of on-site oil treatment. Nitrogen injection was simulated in laboratory PVT unit. Then dehydration experiments with treated water/oil emulsion were conducted under standard conditions at different temperatures and demulsifier dosages.

Key words:

​

enhanced oil recovery methods, nitrogen injection technology, gas injection, oil treatment, oil dehydration, demulsification, effect on treatment
