Design of a downhole acoustic emitter for impact on the productive formation and enhanced oil recovery

Abstract

In this paper deals with the issues of designing a downhole acoustic emitter designed to influence the productive formation in order to intensify oil production. The paper analyses acoustic technologies used in the oil industry, focusing on their impact on physical and chemical processes in the reservoir, such as reducing oil viscosity, improving rock permeability and increasing hydrocarbon production. A new method of impact using acoustic waves generated by a modernized emitter based on the jet-driven Helmholtz oscillator is developed. The experimental study of pressure oscillation generation on the emitter model is presented, and the economic efficiency and prospects of application of this technology in conditions of various geological formations are estimated. The work is of practical importance for optimization of methods of oil production intensification and development of new technologies to increase the degree of hydrocarbon recovery from the fields.
