SET OF EQUIPMENT FOR VIBRATION WAVE IMPACT ON HYDROCARBONS CONTAINING FORMATION Russian patent published in 2018 - IPC E21B28/00 E21B43/25 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, and specifically to the filtration pressure waves generation devices for the hydrocarbon containing formation vibration wave treatment, and can be used to intensify the oil and gas production from productive formations. Set of equipment for vibration wave impact on the hydrocarbon-containing formation includes a central short-wave hydrodynamic generator, located in the well at the perforation interval level on the tubing string, through the wellhead interconnected with a discharge line and connected to the distribution unit by the working fluid discharge line, equipped with interconnected with the control module test-measuring elements, information connected to the reservoir parameters control elements, and interconnected to the resonator-converter long-wave hydrodynamic generator. In the discharge line between the distribution unit and the wellhead fittings a bypass is installed. Long-wave hydrodynamic generator is connected to the discharge line parallel to the bypass and is made in the form of in series installed on the distribution unit side check valve, hydro-pneumatic accumulator and a shut-off and control device. Resonator converter is the tubing string. Set contains at least one additional short-wave hydrodynamic generator, equipped with a switching device, located in the adjacent well at the perforation interval level on the tubing string and hydraulically connected to the equipped with a switching device central short-wave hydrodynamic generator.

EFFECT: enabling restoration of the reservoir design filtration properties in the wells continuous operation process with the expansion of the vibration wave impact zone on the well cluster area and simplification of the design, increase in the ease of operation and reducing time costs.
