FIELD: oil and gas industry, particularly well survey, namely acoustic borehole logging.
SUBSTANCE: method involves lowering electroacoustic transducer unit in borehole; initiating elastic vibrations in well by means of elastic wave source and recording the elastic vibrations by receivers; installing deflectors from both sides of electroacoustic transducer unit and performing acoustic borehole logging. Reflected surface acoustic waves are recorded by electroacoustic transducer unit movement along borehole along with reflectors.
EFFECT: increased accuracy of surface acoustic wave characteristics determination.
