Abstract:In order to study the change of seismic wave energy and frequency in layered near-surface,we carry out physical simulation tests.Based on this simulation,certain frequency components have tuned amplification effects when the near-surface consists of rock inter-beds,and if seismic frequency components have tuned amplification strong seismic energy will be recorded in good near-surface conditions.In order to study the influence of bare limestone on seismic energy,we conduct some field tests.The following observations are obtained:A.The main explosive stress energy concentrates in several thousand MHz which attenuates rapidly,while low-frequency energy is recorded; B.Low-frequency mixed with stress wave forms seismic wavelet.Seismic wavelet energy is rather weak due to limestone thickness and density,so recorded seismic wave energy is weak in carbonate areas; C.In limestone near-surface areas,reflection quality is very poor with the distortion of amplitude,frequency and phase,which makes more difficult in carbonate exploration.Our research results might be a reference for hydrocarbon exploration and development in carbonate areas.
