| 摘 要： | 广西十万大山地区,地表地质特征不一,多为灰岩出露区或火成岩风化剥蚀区,岩石的硬度、密度及脆性都较大,其速度也较高,该区水源缺乏,激发和接收的介质耦合条件很差,造成了数据采集时激发和接收都很困难。针对上述情况,在该地区应用新型震源(爆炸地震锤)、变观观测系统和多种压噪方法进行资料采集工作,取得了较好的效果。

| Abstract: | The surface geology in Shiwan mountainous region varies due to the different surface conditions. The geology is characterized by limestone outcrops and weathering igneous rocks. The rocks are high in hardness, density, fragility, as well as velocity. The lack of water source and poor coupling aggravate the difficulties in shooting and receiving during seismic data acquisition. Desired results were yielded by adoption of new energy source, flexible geometry, and a combination of noise attenuation methods in data acquisition. |
