Downhole acoustic device for treating the bottomhole regions of oil and gas reservoirs

摘要

This invention relates to the oil and gas industry and can be used for intensifying the production of well fluids. The present downhole acoustic apparatus comprises an upper head for attachment to a logging cable or coiled tubing, an acoustic emitter and a lower guiding head. The emitter consists of a body with piezoelectric transducers, comprised of piezoceramic discs, arranged perpendicular to the axis of the body. Emitter bodies are formed in the shape of cylinders from a metal with a milled surface and are connected to each other by means of a rubber-plastic filler. This provides an increase in the acoustic power of radiation in a radial direction and makes it possible to treat horizontal and lateral wells.
