戈壁地区不同震源激发效果的对比分析

Comparative analysis of the different shooting methods' effect in Gobi region

摘要: 以新疆哈密地区某煤田的三维地震勘探为例，选择同一区域、相同观测系统，分别采用炸药震源和可控震源激发，对其原始单炮记录和成果剖面进行了对比分析。结果发现：戈壁地区地震激发时炸药震源和可控震源在控制资料质量方面各有优势；原始单炮记录上，炸药震源原始单炮高频信号的频带较宽，而可控震源压制环境噪声效果更好；时间剖面上，可控震源的浅层反射波层次丰富、分辨率高于炸药震源，对尖灭点以及断层的显示更为清晰。

Abstract: In the case of 3-D seismic exploration of Hami region, the records and profiles of single shoot in the same area and observing system shows:both explosive source and vibrator have their own advantages in terms of data quality control, and according to the geological conditions of the region, playing their respective advantages is the best way of data collection.
