SYSTEM (Options) and a method for detecting acoustic signals coming from the well

摘要

FIELD: oil and gas industry.;SUBSTANCE: detection system of acoustic signals includes delivery pipe string for supply of heated fluid medium that generates acoustic signal, acoustic detector and acoustic signal analyser. Acoustic detector detects acoustic signal, and acoustic signal analyser interprets the detected acoustic signal. At that, delivery pipe string includes the first oscillatory device providing the supply of fluid medium flow to the well shaft in oscillating mode, and the above acoustic signal is created with pressure oscillations in fluid medium.;EFFECT: receiving the information on the system state.;15 cl, 10 dwg
