Processes of vibroimpact treatment of wells

Abstract

The article presents the results of statistical processing of patent and scientific and technical information published in Russia, Great Britain, China, USA, EU countries, Japan on the problem of vibration shock treatment of injection wells, which is used to clean the bottom-hole formation zone from mechanical impurities, corrosion products, asphalt resin paraffin oil components. It was revealed that about 90% of the information is presented in journal articles, conference materials and patents. To a lesser extent, information is presented in books and dissertation research. There are practically no educational and methodological publications. The publication activity is devoted to the oscillatory movement of rock particles in a productive formation, the effect on rheological properties, the reduction of hydraulic resistance, the destruction of oil-water emulsions, the effect on the deposition of salts and paraffins.
