Restoration of intake capacity of injection well by vibrations

Abstract

Abstract Nowadays deterioration of productivity and intake capacity of wells cause different problems in exploitation of oil and gas fields. It happens because of some irreversible physicochemical processes in the bottomhole formation zone: swelling of clay materials, colmation, formation of stable emulsions, confluence of salts, iron oxides etc. Various methods and technologies are used to solve these problems. However, they have disadvantages, for example, material and energy intensity, short-lived equipment, technological complexity. The method of pulse action by various vibrations seems to be the most effective solution. Vibrations are mechanisms that create controlled fluctuations of the working body influencing a recycled material and a reservoir. Now they are widely used in different industries.
