Wave technologies for intensifying oil and gas extraction for fields at a late stage of development

Abstract

One of the promising areas of research in the field of increasing oil recovery from reservoirs is the study of the influence of elastic vibrations on the productive reservoir. Research on the influence of elastic vibrations on stagnant oil zones in an oil reservoir in order to increase the oil recovery factor is at an early stage. The purpose of this work is to evaluate the effectiveness of using one of the wave methods to increase oil recovery. theoretical and experimental studies of the influence of elastic vibrations on changes in the parameters of the bottomhole zones of the formation and, as a consequence, increasing the productivity of oil wells and the oil recovery factor in oil fields. The work will analyze the wave method of influencing reservoir systems, such as acoustic, and evaluate the effectiveness of this method on changing the characteristics of the reservoir system. The work will conduct various studies on the practical application of wave methods. The effect of the wave method on the components and viscosity of heavy crude oil will also be studied. The proposed wave action creates the opportunity to exploit fields at later stages of development, which are characterized by a high content of asphaltenes, resins and paraffins. The results of the wave impact confirmed the effectiveness of this technology, which made it possible to double the turnaround time.
