发明名称 METHOD FOR ACOUSTIC-EMISSION CONTROL AND DIAGNOSTICS OF RESERVOIRS FOR STORAGE OF LIQUEFIED GAS
摘要 FIELD: technology for acoustic-emission control and diagnostics of reservoirs for storage of liquefied gas. ^ SUBSTANCE: in accordance to method, acoustics properties of reservoir are studied, speed of expansion of stress waves, fading degree, type of oscillations, noise level are determined, primary transformers are positioned, using received data, reservoir is loaded, acoustic emission signals are registered before moment of arrival at primary transformer of first false impulse of acoustic emission, acoustic emission signals are processed, while for duration of processing equipment, registering acoustic emission signals, is blocked, and registration is renewed until full fading of oscillations caused by impulse of acoustic emission, on basis of which technical condition of reservoir is evaluated. Time of arrival of first false impulse of acoustic emission at primary transformer and time left until full fading of oscillations in reservoir are determined mathematically on basis of result of research of acoustic properties of reservoir. ^ EFFECT: increased productiveness and precision when detecting defects during control and diagnostics of technical condition of reservoirs for storage of liquefied gas.
