The techniques and technology of hydroshock wave impact upon the near-wellbore formation zone during work over in OJSC 'TATNEFT'

摘要

Wave impact on the oil reservoir for enhanced oil recovery and enhanced oil is one of the promising areas that could reduce the rate of decline of world oil production. The paper presents the results of the development and use of technical means and technologies with shock-wave impact on the oil reservoir on a wide range of low and sub infra low frequencies.The description of the valve-ejector devices for UEGOS hydropercussion-wave action, examples of the technology, the results of pilot projects (23 wells.) in JSC "Tatneft" during workover at the stage of the processing of the near-well zone. The prospects for the use of technology are shown - for deep barochemical, interwell formation treatment for hydropercussion wave acid fracturing etc.Equipment and technologies are available for a wide industrial use while repairing wells and pilot projects on hydropercussion-wave treatment of oil reservoirs to enhance oil recovery and identification of new technological capabilities of the method
