| 摘 要： | 炸药震源是陆上地震勘探使用最广泛的激发方式。针对虚反射界面对其激发出的子波所产生的影响，从频率和振幅2个方面进行了分析。经过野外实地试验，确定利用虚反射调查和激发子波监测的定量分析技术可较准确地选择激发井的深度。尤其在深层地震勘探中，将激发深度选择在虚反射界面1／4波长处，可获得能量较强的激发子波，有利于提高深层的反射能量，改善地震剖面的整体品质。

| Abstract: | Dynamite is the main source in the onshore seismic acquisition at present. It's important to determine the optimal hole depth to obtain better seismic records for various exploration targets. This article present a method of determining hole depth scientifically by means of analyze dynamite source wavelets, the phantom reflection effected on wavelet blazed, analyzed by frequency and amplitude and got great progress in the deep layer seismic exploration in east China. Especially the depth chose the 1/4 of wavelength in the deep prospecting. It is propitious to improve the reflection energy and seismic section quality and received the stronger wavelet. The author also argued that we should use different hole depths according to the various geologic requirements and weathering layers. |
