A method is proposed for remote detection of leaks of productive hydrocarbons from underground main pipelines. The method involves impact on the soil adjacent to the tubing route by the acoustic field of the ultrasonic wave, at which its intensive degassing takes place accompanied by gas evolution from the surface of the earth. In parallel with the process of exposure, a chromatographic analysis of the composition of the released gas is carried out. It is described a device that realizes this method of detecting leaks of productive hydrocarbons associated with local tub damage. The technical solution of the device assumes the presence of an ultrasonic magnetostrictive radiator with power consumption ~ kW and an acoustic waveguide, with which the ultrasonic wave is directed to the earth's surface. A description is given of an ultrasonic radiator based on a magnetostrictor with a toroidal core, made in the form of an assembly of permangled plates. A small-size chromatograph of a batch production can be used in the apparatus complex. Dimensions and weight of the whole equipment complex allows its placement on a Gazel type vehicle. The results of field tests of the proposed method and the equipment that implements it are given. By their results, one can judge the effectiveness of the proposed method and the hardware complex.
