tting more and more important.However,it is no long time to apply signal extraction technique to full waveform acoustic logs,extraction of wave componets cant's be extracted well,it is very difficult to use thier information to determine parameters of formation to analysis the atructure of reservior,and to direct the enggnerray of production. 收起
