为研究不同目的层对激发因素的响应特征,在黄土塬区首次探索将检波器放入井中几千米以下的勘探目的层进行地震波特性对比研究。通过井中接收分析所研究目的层在地面常规激发后经过一次衰减后和经过反射二次衰减后的能量、频谱、子波等特性变化规律,更准确掌握不同目的层对不同地震激发参数的响应特征,从而针对不同的勘探目的层科学设计激发参数。
In order to study the response characteristics of different target layers to the excitation factors, the seismic characteristics of the exploration target layers with the geophones placed below several kilometers in the well were investigated for the first time in the Loess Plateau. According to the variation of energy, frequency spectrum and wavelet in the target layer under normal ground excitation and after secondary attenuation by reflection, the response characteristics of different target layers to different seismic excitation parameters are more accurately grasped. So as to design the excitation parameters scientifically for different exploration target layers.
