SEISMIC ACQUISITION ANALYSIS IN THE AREA OF HIGH VELOCITY SHIELDING LAYERS
高速屏蔽层下地震数据的采集

In the seismic exploration,it is difficult for the seismic wave to transmit the shielding layer of high velocity,so it is difficult to acquire efficient seismic data of reflected wave from the stratum below the high velocity shield layer by the conventional methods.According to Snell law and Zoeppritz equation,the paper studies the rule of energy's distribution of elastic wave on the interface,obtain the rule of received energy variation with offset or angle,and also study the relation of the exploding frequency and the resolution.In addition,the paper proposes some advice on seismic acquisition in the area of high velocity shielding layers,which is very useful for practical seismic acquisition.
