Abstract
The invention relates to the oil and gas industry and can be used for extracting oil. The inventive device comprises a well arrangement provided with two or more acoustic radiators (1) which are arranged in the lower part thereon and open to the environment by means of windows embodied in the walls of a logging instrument body. Each radiator is provided with two reflectors in the form of cone (12) which are coaxially arranged in an individual manner on both sides of the end of the radiator. The height of the cone is equal to the radius of the reflector, the top thereof having an angle of 90° being oriented towards said reflector. The distance between the ends of the adjacent conical reflectors (12) d ranges from 2 mm to 10 % of the height thereof, the distance from the end of the radiator (1) to the top of the reflector (12) being selected according to the condition of maximum transmission of a mean power to the formation and calculated in accordance with the following formula: A = nμ/8-R, Wherein: n= 1,5,9 μ is an acoustic wavelength R is the internal radius of a well tube. Each acoustical reflector is formed by two identical piezo packages (2) and (3) having a length equal to a quarter length of the acoustic wave in the piezo element material. Said piezo packages are provided with a common fixing base (4) disposed therebetween, the lateral piezo elements of the piezo packages (2) and (3) having an equal polarity. Said invention increases the efficiency factor and the performance of the oil production.
